For the LQFP100 and BGA100 packages, only FSMC Bank1 and Bank2 are available. Bank1 can only support a multiplexed NOR/PSRAM memory using the NE1 Chip Select. Bank2 can only support a 16- or 8-bit NAND Flash memory using the NCE2 Chip Select. The interrupt line cannot be used since Port G is not available in this package. 2. The SPI2 and SPI3 interfaces give the flexibility to work in an exclusive way in either the SPI mode or the I2S audio mode. DS5792 Rev 13 11/143 135

Description STM32F103xC, STM32F103xD, STM32F103xE 2.2 Full compatibility throughout the family The STM32F103xC/D/E is a complete family whose members are fully pin-to-pin, software and feature compatible. In the reference manual, the STM32F103x4 and STM32F103x6 are identified as low-density devices, the STM32F103x8 and STM32F103xB are referred to as medium-density devices and the STM32F103xC, STM32F103xD and STM32F103xE are referred to as high-density devices. Low-density and high-density devices are an extension of the STM32F103x8/B medium- density devices, they are specified in the STM32F103x4/6 and STM32F103xC/D/E datasheets, respectively. Low-density devices feature lower Flash memory and RAM capacities, less timers and peripherals. High-density devices have higher Flash memory and RAM capacities, and additional peripherals like SDIO, FSMC, I2S and DAC while remaining fully compatible with the other members of the family. The STM32F103x4, STM32F103x6, STM32F103xC, STM32F103xD and STM32F103xE are a drop-in replacement for the STM32F103x8/B devices, allowing the user to try different memory densities and providing a greater degree of freedom during the development cycle. Moreover, the STM32F103xx performance line family is fully compatible with all existing STM32F101xx access line and STM32F102xx USB access line devices. Table 3.

STM32F103xC, STM32F103xD, STM32F103xE Description 2.3 Overview 2.3.1 Arm® Cortex®-M3 core with embedded Flash and SRAM The Arm Cortex®-M3 processor is the latest generation of Arm processors for embedded systems. It has been developed to provide a low-cost platform that meets the needs of MCU implementation, with a reduced pin count and low-power consumption, while delivering outstanding computational performance and an advanced system response to interrupts. The Arm Cortex®-M3 32-bit RISC processor features exceptional code-efficiency, delivering the high-performance expected from an Arm core in the memory size usually associated with 8- and 16-bit devices. With its embedded Arm core, STM32F103xC, STM32F103xD and STM32F103xE performance line family is compatible with all Arm tools and software. Figure1 shows the general block diagram of the device family. 2.3.2 Embedded Flash memory Up to 512 Kbytes of embedded Flash is available for storing programs and data. 2.3.3 CRC (cyclic redundancy check) calculation unit The CRC (cyclic redundancy check) calculation unit is used to get a CRC code from a 32-bit data word and a fixed generator polynomial. Among other applications, CRC-based techniques are used to verify data transmission or storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a means of verifying the Flash memory integrity. The CRC calculation unit helps compute a signature of the software during runtime, to be compared with a reference signature generated at link- time and stored at a given memory location. 2.3.4 Embedded SRAM Up to 64 Kbytes of embedded SRAM accessed (read/write) at CPU clock speed with 0 wait states. 2.3.5 FSMC (flexible static memory controller) The FSMC is embedded in the STM32F103xC, STM32F103xD and STM32F103xE performance line family. It has four Chip Select outputs supporting the following modes: PC Card/Compact Flash, SRAM, PSRAM, NOR and NAND. Functionality overview: • The three FSMC interrupt lines are ORed in order to be connected to the NVIC • Write FIFO • Code execution from external memory except for NAND Flash and PC Card • The targeted frequency, f , is HCLK/2, so external access is at 36 MHz when HCLK CLK is at 72MHz and external access is at 24 MHz when HCLK is at 48 MHz DS5792 Rev 13 15/143 135

Description STM32F103xC, STM32F103xD, STM32F103xE 2.3.6 LCD parallel interface The FSMC can be configured to interface seamlessly with most graphic LCD controllers. It supports the Intel 8080 and Motorola 6800 modes, and is flexible enough to adapt to specific LCD interfaces. This LCD parallel interface capability makes it easy to build cost- effective graphic applications using LCD modules with embedded controllers or high- performance solutions using external controllers with dedicated acceleration. 2.3.7 Nested vectored interrupt controller (NVIC) The STM32F103xC, STM32F103xD and STM32F103xE performance line embeds a nested vectored interrupt controller able to handle up to 60 maskable interrupt channels (not including the 16 interrupt lines of Cortex®-M3) and 16 priority levels. • Closely coupled NVIC gives low latency interrupt processing • Interrupt entry vector table address passed directly to the core • Closely coupled NVIC core interface • Allows early processing of interrupts • Processing of late arriving higher priority interrupts • Support for tail-chaining • Processor state automatically saved • Interrupt entry restored on interrupt exit with no instruction overhead This hardware block provides flexible interrupt management features with minimal interrupt latency. 2.3.8 External interrupt/event controller (EXTI) The external interrupt/event controller consists of 19 edge detector lines used to generate interrupt/event requests. Each line can be independently configured to select the trigger event (rising edge, falling edge, both) and can be masked independently. A pending register maintains the status of the interrupt requests. The EXTI can detect an external line with a pulse width shorter than the Internal APB2 clock period. Up to 112 GPIOs can be connected to the 16 external interrupt lines. 2.3.9 Clocks and startup System clock selection is performed on startup, however the internal RC 8 MHz oscillator is selected as default CPU clock on reset. An external 4-16 MHz clock can be selected, in which case it is monitored for failure. If failure is detected, the system automatically switches back to the internal RC oscillator. A software interrupt is generated if enabled. Similarly, full interrupt management of the PLL clock entry is available when necessary (for example with failure of an indirectly used external oscillator). Several prescalers allow the configuration of the AHB frequency, the high speed APB (APB2) and the low speed APB (APB1) domains. The maximum frequency of the AHB and the high speed APB domains is 72 MHz. The maximum allowed frequency of the low speed APB domain is 36 MHz. See Figure2 for details on the clock tree. 16/143 DS5792 Rev 13

STM32F103xC, STM32F103xD, STM32F103xE Description 2.3.10 Boot modes At startup, boot pins are used to select one of three boot options: • Boot from user Flash: you have an option to boot from any of two memory banks. By default, boot from Flash memory bank 1 is selected. You can choose to boot from Flash memory bank 2 by setting a bit in the option bytes. • Boot from system memory • Boot from embedded SRAM The boot loader is located in system memory. It is used to reprogram the Flash memory by using USART1. 2.3.11 Power supply schemes • V = 2.0 to 3.6 V: external power supply for I/Os and the internal regulator. DD Provided externally through V pins. DD • V , V = 2.0 to 3.6 V: external analog power supplies for ADC, DAC, Reset SSA DDA blocks, RCs and PLL (minimum voltage to be applied to VDDA is 2.4 V when the ADC or DAC is used). V and V must be connected to V and V , respectively. DDA SSA DD SS • V = 1.8 to 3.6 V: power supply for RTC, external clock 32 kHz oscillator and backup BAT registers (through power switch) when V is not present. DD For more details on how to connect power pins, refer to Figure12: Power supply scheme. 2.3.12 Power supply supervisor The device has an integrated power-on reset (POR)/power-down reset (PDR) circuitry. It is always active, and ensures proper operation starting from/down to 2 V. The device remains in reset mode when V is below a specified threshold, V , without the need for an DD POR/PDR external reset circuit. The device features an embedded programmable voltage detector (PVD) that monitors the V /V power supply and compares it to the V threshold. An interrupt can be DD DDA PVD generated when V /V drops below the V threshold and/or when V /V is DD DDA PVD DD DDA higher than the V threshold. The interrupt service routine can then generate a warning PVD message and/or put the MCU into a safe state. The PVD is enabled by software. Refer to Table12: Embedded reset and power control block characteristics for the values of V and V . POR/PDR PVD 2.3.13 Voltage regulator The regulator has three operation modes: main (MR), low-power (LPR) and power down. • MR is used in the nominal regulation mode (Run) • LPR is used in the Stop modes. • Power down is used in Standby mode: the regulator output is in high impedance: the kernel circuitry is powered down, inducing zero consumption (but the contents of the registers and SRAM are lost) This regulator is always enabled after reset. It is disabled in Standby mode. DS5792 Rev 13 17/143 135

Description STM32F103xC, STM32F103xD, STM32F103xE 2.3.14 Low-power modes The STM32F103xC, STM32F103xD and STM32F103xE performance line supports three low-power modes to achieve the best compromise between low-power consumption, short startup time and available wakeup sources: • Sleep mode In Sleep mode, only the CPU is stopped. All peripherals continue to operate and can wake up the CPU when an interrupt/event occurs. • Stop mode Stop mode achieves the lowest power consumption while retaining the content of SRAM and registers. All clocks in the 1.8 V domain are stopped, the PLL, the HSI RC and the HSE crystal oscillators are disabled. The voltage regulator can also be put either in normal or in low-power mode. The device can be woken up from Stop mode by any of the EXTI line. The EXTI line source can be one of the 16 external lines, the PVD output, the RTC alarm or the USB wakeup. • Standby mode The Standby mode is used to achieve the lowest power consumption. The internal voltage regulator is switched off so that the entire 1.8 V domain is powered off. The PLL, the HSI RC and the HSE crystal oscillators are also switched off. After entering Standby mode, SRAM and register contents are lost except for registers in the Backup domain and Standby circuitry. The device exits Standby mode when an external reset (NRST pin), an IWDG reset, a rising edge on the WKUP pin, or an RTC alarm occurs. Note: The RTC, the IWDG, and the corresponding clock sources are not stopped by entering Stop or Standby mode. 2.3.15 DMA The flexible 12-channel general-purpose DMAs (7 channels for DMA1 and 5 channels for DMA2) are able to manage memory-to-memory, peripheral-to-memory and memory-to- peripheral transfers. The two DMA controllers support circular buffer management, removing the need for user code intervention when the controller reaches the end of the buffer. Each channel is connected to dedicated hardware DMA requests, with support for software trigger on each channel. Configuration is made by software and transfer sizes between source and destination are independent. The DMA can be used with the main peripherals: SPI, I2C, USART, general-purpose, basic and advanced-control timers TIMx, DAC, I2S, SDIO and ADC. 2.3.16 RTC (real-time clock) and backup registers The RTC and the backup registers are supplied through a switch that takes power either on V supply when present or through the V pin. The backup registers are forty-two 16-bit DD BAT registers used to store 84 bytes of user application data when V power is not present. DD They are not reset by a system or power reset, and they are not reset when the device wakes up from the Standby mode. The real-time clock provides a set of continuously running counters which can be used with suitable software to provide a clock calendar function, and provides an alarm interrupt and a 18/143 DS5792 Rev 13

STM32F103xC, STM32F103xD, STM32F103xE Description periodic interrupt. It is clocked by a 32.768 kHz external crystal, resonator or oscillator, the internal low-power RC oscillator or the high-speed external clock divided by 128. The internal low-speed RC has a typical frequency of 40 kHz. The RTC can be calibrated using an external 512 Hz output to compensate for any natural quartz deviation. The RTC features a 32-bit programmable counter for long term measurement using the Compare register to generate an alarm. A 20-bit prescaler is used for the time base clock and is by default configured to generate a time base of 1 second from a clock at 32.768 kHz. 2.3.17 Timers and watchdogs The high-density STM32F103xC/D/E performance line devices include up to two advanced- control timers, up to four general-purpose timers, two basic timers, two watchdog timers and a SysTick timer. Table4 compares the features of the advanced-control, general-purpose and basic timers. Table 4.

Description STM32F103xC, STM32F103xD, STM32F103xE Advanced-control timers (TIM1 and TIM8) The two advanced-control timers (TIM1 and TIM8) can each be seen as a three-phase PWM multiplexed on 6 channels. They have complementary PWM outputs with programmable inserted dead-times. They can also be seen as a complete general-purpose timer. The 4 independent channels can be used for: • Input capture • Output compare • PWM generation (edge or center-aligned modes) • One-pulse mode output If configured as a standard 16-bit timer, it has the same features as the TIMx timer. If configured as the 16-bit PWM generator, it has full modulation capability (0-100%). In debug mode, the advanced-control timer counter can be frozen and the PWM outputs disabled to turn off any power switch driven by these outputs. Many features are shared with those of the general-purpose TIM timers which have the same architecture. The advanced-control timer can therefore work together with the TIM timers via the Timer Link feature for synchronization or event chaining. General-purpose timers (TIMx) There are up to 4 synchronizable general-purpose timers (TIM2, TIM3, TIM4 and TIM5) embedded in the STM32F103xC, STM32F103xD and STM32F103xE performance line devices. These timers are based on a 16-bit auto-reload up/down counter, a 16-bit prescaler and feature 4 independent channels each for input capture/output compare, PWM or one- pulse mode output. This gives up to 16 input captures / output compares / PWMs on the largest packages. The general-purpose timers can work together with the advanced-control timer via the Timer Link feature for synchronization or event chaining. Their counter can be frozen in debug mode. Any of the general-purpose timers can be used to generate PWM outputs. They all have independent DMA request generation. These timers are capable of handling quadrature (incremental) encoder signals and the digital outputs from 1 to 3 hall-effect sensors. Basic timers TIM6 and TIM7 These timers are mainly used for DAC trigger generation. They can also be used as a generic 16-bit time base. Independent watchdog The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is clocked from an independent 40 kHz internal RC and as it operates independently from the main clock, it can operate in Stop and Standby modes. It can be used either as a watchdog to reset the device when a problem occurs, or as a free running timer for application timeout management. It is hardware or software configurable through the option bytes. The counter can be frozen in debug mode. Window watchdog The window watchdog is based on a 7-bit downcounter that can be set as free running. It can be used as a watchdog to reset the device when a problem occurs. It is clocked from 20/143 DS5792 Rev 13

STM32F103xC, STM32F103xD, STM32F103xE Description the main clock. It has an early warning interrupt capability and the counter can be frozen in debug mode. SysTick timer This timer is dedicated to real-time operating systems, but could also be used as a standard down counter. It features: • A 24-bit down counter • Autoreload capability • Maskable system interrupt generation when the counter reaches 0. • Programmable clock source 2.3.18 I²C bus Up to two I²C bus interfaces can operate in multimaster and slave modes. They can support standard and fast modes. They support 7/10-bit addressing mode and 7-bit dual addressing mode (as slave). A hardware CRC generation/verification is embedded. They can be served by DMA and they support SMBus 2.0/PMBus. 2.3.19 Universal synchronous/asynchronous receiver transmitters (USARTs) The STM32F103xC, STM32F103xD and STM32F103xE performance line embeds three universal synchronous/asynchronous receiver transmitters (USART1, USART2 and USART3) and two universal asynchronous receiver transmitters (UART4 and UART5). These five interfaces provide asynchronous communication, IrDA SIR ENDEC support, multiprocessor communication mode, single-wire half-duplex communication mode and have LIN Master/Slave capability. The USART1 interface is able to communicate at speeds of up to 4.5 Mbit/s. The other available interfaces communicate at up to 2.25 Mbit/s. USART1, USART2 and USART3 also provide hardware management of the CTS and RTS signals, Smart Card mode (ISO 7816 compliant) and SPI-like communication capability. All interfaces can be served by the DMA controller except for UART5. 2.3.20 Serial peripheral interface (SPI) Up to three SPIs are able to communicate up to 18 Mbits/s in slave and master modes in full-duplex and simplex communication modes. The 3-bit prescaler gives 8 master mode frequencies and the frame is configurable to 8 bits or 16 bits. The hardware CRC generation/verification supports basic SD Card/MMC modes. All SPIs can be served by the DMA controller. 2.3.21 Inter-integrated sound (I2S) Two standard I2S interfaces (multiplexed with SPI2 and SPI3) are available, that can be operated in master or slave mode. These interfaces can be configured to operate with 16/32 bit resolution, as input or output channels. Audio sampling frequencies from 8 kHz up to 48kHz are supported. When either or both of the I2S interfaces is/are configured in master DS5792 Rev 13 21/143 135

Description STM32F103xC, STM32F103xD, STM32F103xE mode, the master clock can be output to the external DAC/CODEC at 256 times the sampling frequency. 2.3.22 SDIO An SD/SDIO/MMC host interface is available, that supports MultiMediaCard System Specification Version 4.2 in three different databus modes: 1-bit (default), 4-bit and 8-bit. The interface allows data transfer at up to 48 MHz in 8-bit mode, and is compliant with SD Memory Card Specifications Version 2.0. The SDIO Card Specification Version 2.0 is also supported with two different databus modes: 1-bit (default) and 4-bit. The current version supports only one SD/SDIO/MMC4.2 card at any one time and a stack of MMC4.1 or previous. In addition to SD/SDIO/MMC, this interface is also fully compliant with the CE-ATA digital protocol Rev1.1. 2.3.23 Controller area network (CAN) The CAN is compliant with specifications 2.0A and B (active) with a bit rate up to 1 Mbit/s. It can receive and transmit standard frames with 11-bit identifiers as well as extended frames with 29-bit identifiers. It has three transmit mailboxes, two receive FIFOs with 3 stages and 14 scalable filter banks. 2.3.24 Universal serial bus (USB) The STM32F103xC, STM32F103xD and STM32F103xE performance line embed a USB device peripheral compatible with the USB full-speed 12 Mbs. The USB interface implements a full-speed (12 Mbit/s) function interface. It has software-configurable endpoint setting and suspend/resume support. The dedicated 48 MHz clock is generated from the internal main PLL (the clock source must use a HSE crystal oscillator). 2.3.25 GPIOs (general-purpose inputs/outputs) Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as input (with or without pull-up or pull-down) or as peripheral alternate function. Most of the GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current- capable. The I/Os alternate function configuration can be locked if needed following a specific sequence in order to avoid spurious writing to the I/Os registers. 2.3.26 ADC (analog to digital converter) Three 12-bit analog-to-digital converters are embedded into STM32F103xC, STM32F103xD and STM32F103xE performance line devices and each ADC shares up to 21 external channels, performing conversions in single-shot or scan modes. In scan mode, automatic conversion is performed on a selected group of analog inputs. Additional logic functions embedded in the ADC interface allow: • Simultaneous sample and hold • Interleaved sample and hold • Single shunt 22/143 DS5792 Rev 13

STM32F103xC, STM32F103xD, STM32F103xE Description The ADC can be served by the DMA controller. An analog watchdog feature allows very precise monitoring of the converted voltage of one, some or all selected channels. An interrupt is generated when the converted voltage is outside the programmed thresholds. The events generated by the general-purpose timers (TIMx) and the advanced-control timers (TIM1 and TIM8) can be internally connected to the ADC start trigger and injection trigger, respectively, to allow the application to synchronize A/D conversion and timers. 2.3.27 DAC (digital-to-analog converter) The two 12-bit buffered DAC channels can be used to convert two digital signals into two analog voltage signal outputs. The chosen design structure is composed of integrated resistor strings and an amplifier in inverting configuration. This dual digital Interface supports the following features: • two DAC converters: one for each output channel • 8-bit or 12-bit monotonic output • left or right data alignment in 12-bit mode • synchronized update capability • noise-wave generation • triangular-wave generation • dual DAC channel independent or simultaneous conversions • DMA capability for each channel • external triggers for conversion • input voltage reference V REF+ Eight DAC trigger inputs are used in the STM32F103xC, STM32F103xD and STM32F103xE performance line family. The DAC channels are triggered through the timer update outputs that are also connected to different DMA channels. DS5792 Rev 13 23/143 135

Description STM32F103xC, STM32F103xD, STM32F103xE 2.3.28 Temperature sensor The temperature sensor has to generate a voltage that varies linearly with temperature. The conversion range is between 2 V < V < 3.6 V. The temperature sensor is internally DDA connected to the ADC1_IN16 input channel which is used to convert the sensor output voltage into a digital value. 2.3.29 Serial wire JTAG debug port (SWJ-DP) The Arm SWJ-DP Interface is embedded, and is a combined JTAG and serial wire debug port that enables either a serial wire debug or a JTAG probe to be connected to the target. The JTAG TMS and TCK pins are shared respectively with SWDIO and SWCLK and a specific sequence on the TMS pin is used to switch between JTAG-DP and SW-DP. 2.3.30 Embedded Trace Macrocell™ The Arm® Embedded Trace Macrocell provides a greater visibility of the instruction and data flow inside the CPU core by streaming compressed data at a very high rate from the STM32F10xxx through a small number of ETM pins to an external hardware trace port analyzer (TPA) device. The TPA is connected to a host computer using USB, Ethernet, or any other high-speed channel. Real-time instruction and data flow activity can be recorded and then formatted for display on the host computer running debugger software.

I = input, O = output, S = supply. 2. FT = 5 V tolerant. 3. Function availability depends on the chosen device. 4. If several peripherals share the same I/O pin, to avoid conflict between these alternate functions only one peripheral should be enabled at a time through the peripheral clock enable bit (in the corresponding RCC peripheral clock enable register). 36/143 DS5792 Rev 13

STM32F103xC, STM32F103xD, STM32F103xE Pinouts and pin descriptions 5. PC13, PC14 and PC15 are supplied through the power switch. Since the switch only sinks a limited amount of current (3 mA), the use of GPIOs PC13 to PC15 in output mode is limited: the speed should not exceed 2 MHz with a maximum load of 30 pF and these IOs must not be used as a current source (e.g. to drive an LED). 6. Main function after the first backup domain power-up. Later on, it depends on the contents of the Backup registers even after reset (because these registers are not reset by the main reset). For details on how to manage these IOs, refer to the Battery backup domain and BKP register description sections in the STM32F10xxx reference manual, available from the STMicroelectronics website: www.st.com. 7. In the WCLSP64 package, the PC3 I/O pin is not bonded and it must be configured by software to output mode (Push-pull) and writing 0 to the data register in order to avoid an extra consumption during low-power modes. 8. Unlike in the LQFP64 package, there is no PC3 in the WLCSP package. The V functionality is provided instead. REF+ 9. This alternate function can be remapped by software to some other port pins (if available on the used package). For more details, refer to the Alternate function I/O and debug configuration section in the STM32F10xxx reference manual, available from the STMicroelectronics website: www.st.com. 10. For the WCLSP64/LQFP64 package, the pins number 5 and 6 are configured as OSC_IN/OSC_OUT after reset, however the functionality of PD0 and PD1 can be remapped by software on these pins. For the LQFP100/BGA100 and LQFP144/BGA144 packages, PD0 and PD1 are available by default, so there is no need for remapping. For more details, refer to Alternate function I/O and debug configuration section in the STM32F10xxx reference manual. 11. For devices delivered in LQFP64 packages, the FSMC function is not available. DS5792 Rev 13 37/143 135

STM32F103xC, STM32F103xD, STM32F103xE Electrical characteristics 5 Electrical characteristics 5.1 Parameter conditions Unless otherwise specified, all voltages are referenced to V . SS 5.1.1 Minimum and maximum values Unless otherwise specified the minimum and maximum values are guaranteed in the worst conditions of ambient temperature, supply voltage and frequencies by tests in production on 100% of the devices with an ambient temperature at T = 25 °C and T = T max (given by A A A the selected temperature range). Data based on characterization results, design simulation and/or technology characteristics are indicated in the table footnotes and are not tested in production. Based on characterization, the minimum and maximum values refer to sample tests and represent the mean value plus or minus three times the standard deviation (mean±3Σ). 5.1.2 Typical values Unless otherwise specified, typical data are based on T = 25 °C, V = 3.3 V (for the A DD 2V≤V ≤3.6V voltage range). They are given only as design guidelines and are not DD tested.

Typically, it is stray between 2 pF and 7 pF. Caution: To avoid exceeding the maximum value of C and C (15 pF) it is strongly recommended L1 L2 to use a resonator with a load capacitance C ≤ 7 pF. Never use a resonator with a load L capacitance of 12.5 pF. Example: if you choose a resonator with a load capacitance of C = 6 pF, and C = 2 pF, L stray then C = C = 8 pF.

Electrical characteristics STM32F103xC, STM32F103xD, STM32F103xE 5.3.11 EMC characteristics Susceptibility tests are performed on a sample basis during device characterization. Functional EMS (electromagnetic susceptibility) While a simple application is executed on the device (toggling 2 LEDs through I/O ports). the device is stressed by two electromagnetic events until a failure occurs. The failure is indicated by the LEDs: • Electrostatic discharge (ESD) (positive and negative) is applied to all device pins until a functional disturbance occurs. This test is compliant with the IEC 61000-4-2 standard. • FTB: A Burst of Fast Transient voltage (positive and negative) is applied to V and DD V through a 100 pF capacitor, until a functional disturbance occurs. This test is SS compliant with the IEC 61000-4-4 standard. A device reset allows normal operations to be resumed. The test results are given in Table41. They are based on the EMS levels and classes defined in application note AN1709. Table 41. EMS characteristics Level/ Symbol Parameter Conditions Class V = 3.3 V, LQFP144, T = +25 °C, Voltage limits to be applied on any I/O pin to DD A V f = 72 MHz 2B FESD induce a functional disturbance HCLK conforms to IEC 61000-4-2 V = 3.3 V, LQFP144, T = +25 Fast transient voltage burst limits to be DD A °C, V applied through 100 pF on V and V 4A EFTB DD SS f = 72 MHz pins to induce a functional disturbance HCLK conforms to IEC 61000-4-4 Designing hardened software to avoid noise problems EMC characterization and optimization are performed at component level with a typical application environment and simplified MCU software. It should be noted that good EMC performance is highly dependent on the user application and the software in particular. Therefore it is recommended that the user applies EMC software optimization and prequalification tests in relation with the EMC level requested for his application. Software recommendations The software flowchart must include the management of runaway conditions such as: • Corrupted program counter • Unexpected reset • Critical Data corruption (control registers...) Prequalification trials Most of the common failures (unexpected reset and program counter corruption) can be reproduced by manually forcing a low state on the NRST pin or the Oscillator pins for 1 second. 86/143 DS5792 Rev 13

STM32F103xC, STM32F103xD, STM32F103xE Electrical characteristics To complete these trials, ESD stress can be applied directly on the device, over the range of specification values. When unexpected behavior is detected, the software can be hardened to prevent unrecoverable errors occurring (see application note AN1015). Electromagnetic Interference (EMI) The electromagnetic field emitted by the device are monitored while a simple application is executed (toggling 2 LEDs through the I/O ports). This emission test is compliant with IEC61967-2 standard which specifies the test board and the pin loading. Table 42.

Electrostatic discharge (ESD) Electrostatic discharges (a positive then a negative pulse separated by 1 second) are applied to the pins of each sample according to each pin combination. The sample size depends on the number of supply pins in the device (3 parts × (n+1) supply pins). This test conforms to the JESD22-A114/C101 standard. Table 43.

Guaranteed by characterization results. Static latch-up Two complementary static tests are required on six parts to assess the latch-up performance: • A supply overvoltage is applied to each power supply pin • A current injection is applied to each input, output and configurable I/O pin These tests are compliant with EIA/JESD 78A IC latch-up standard.

Electrical sensitivities Symbol Parameter Conditions Class LU Static latch-up class T = +105 °C conforming to JESD78A II level A A 5.3.13 I/O current injection characteristics As a general rule, current injection to the I/O pins, due to external voltage below V or SS above V (for standard, 3 V-capable I/O pins) should be avoided during normal product DD operation. However, in order to give an indication of the robustness of the microcontroller in cases when abnormal injection accidentally happens, susceptibility tests are performed on a sample basis during device characterization. Functional susceptibilty to I/O current injection While a simple application is executed on the device, the device is stressed by injecting current into the I/O pins programmed in floating input mode. While current is injected into the I/O pin, one at a time, the device is checked for functional failures. The failure is indicated by an out of range parameter: ADC error above a certain limit (>5 LSB TUE), out of spec current injection on adjacent pins or other functional failure (for example reset, oscillator frequency deviation). The test results are given in Table45 Table 45.

Refer to Table59 for the values of R , R and C . AIN ADC ADC 2. C represents the capacitance of the PCB (dependent on soldering and PCB layout quality) plus the parasitic pad capacitance (roughly 7pF). A high C value will downgrade conversion accuracy. To remedy parasitic this, f should be reduced. ADC General PCB design guidelines Power supply decoupling should be performed as shown in Figure59 or Figure60, depending on whether V is connected to V or not.

Package information STM32F103xC, STM32F103xD, STM32F103xE 6.7 Thermal characteristics The maximum chip junction temperature (T max) must never exceed the values given in J Table10: General operating conditions on page44. The maximum chip-junction temperature, T max, in degrees Celsius, may be calculated J using the following equation: T max = T max + (P max x Θ ) J A D JA Where: • T max is the maximum ambient temperature in °C, A • Θ is the package junction-to-ambient thermal resistance, in °C/W, JA • P max is the sum of P max and P max (P max = P max + P max), D INT I/O D INT I/O • P max is the product of I andV , expressed in Watts. This is the maximum chip INT DD DD internal power. P max represents the maximum power dissipation on output pins where: I/O PI/O max = Σ (VOL × IOL) + Σ((VDD – VOH) × IOH), taking into account the actual VOL / IOL and VOH / IOH of the I/Os at low and high level in the application.

STM32F103xC, STM32F103xD, STM32F103xE Package information 6.7.2 Selecting the product temperature range When ordering the microcontroller, the temperature range is specified in the ordering information scheme shown in Table75: Ordering information scheme. Each temperature range suffix corresponds to a specific guaranteed ambient temperature at maximum dissipation and, to a specific maximum junction temperature. As applications do not commonly use the STM32F103xC, STM32F103xD and STM32F103xE at maximum dissipation, it is useful to calculate the exact power consumption and junction temperature to determine which temperature range will be best suited to the application. The following examples show how to calculate the temperature range needed for a given application. Example 1: High-performance application Assuming the following application conditions: Maximum ambient temperature T = 82 °C (measured according to JESD51-2), Amax I = 50 mA, V = 3.5 V, maximum 20 I/Os used at the same time in output at low DDmax DD level with I = 8 mA, V = 0.4 V and maximum 8 I/Os used at the same time in output OL OL at low level with I = 20 mA, V = 1.3 V OL OL P 50 mA × 3.5 V= 175 mW INTmax = P × 8 mA × 0.4 V + 8 × 20 mA × 1.3 V = 272 mW IOmax = 20 This gives: P = 175 mW and P = 272 mW: INTmax IOmax P 175 272 = 447 mW Dmax = + Thus: P = 447 mW Dmax Using the values obtained in Table74 T is calculated as follows: Jmax – For LQFP100, 46 °C/W T = 82 °C + (46 °C/W × 447 mW) = 82 °C + 20.6 °C = 102.6 °C Jmax This is within the range of the suffix 6 version parts (–40 < T < 105 °C). J In this case, parts must be ordered at least with the temperature range suffix 6 (see Table75: Ordering information scheme). Example 2: High-temperature application Using the same rules, it is possible to address applications that run at high ambient temperatures with a low dissipation, as long as junction temperature T remains within the J specified range. Assuming the following application conditions: Maximum ambient temperature T = 115 °C (measured according to JESD51-2), Amax I = 20 mA, V = 3.5 V, maximum 20 I/Os used at the same time in output at low DDmax DD level with I = 8 mA, V = 0.4 V OL OL P 20 mA × 3.5 V= 70 mW INTmax = P × 8 mA × 0.4 V = 64 mW IOmax = 20 This gives: P = 70 mW and P = 64 mW: INTmax IOmax P 70 64 = 134 mW Dmax = + Thus: P = 134 mW Dmax DS5792 Rev 13 133/143 135

Package information STM32F103xC, STM32F103xD, STM32F103xE Using the values obtained in Table74 T is calculated as follows: Jmax – For LQFP100, 46 °C/W T = 115 °C + (46 °C/W × 134 mW) = 115 °C + 6.2 °C = 121.2 °C Jmax This is within the range of the suffix 7 version parts (–40 < T < 125 °C). J In this case, parts must be ordered at least with the temperature range suffix 7 (see Table75: Ordering information scheme). Figure 79.
