dsPIC30F3014/4013 Data Sheet High-Performance, 16-bit Digital Signal Controllers  2010 Microchip Technology Inc. DS70138G

Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving.

If an ISR of a certain priority uses the PUSH.S and POP.S instructions for fast context saving, then a higher priority ISR should not include the same instruc- tions. Users must save the key registers in software during a lower priority interrupt if the higher priority ISR uses fast context saving. DS70138G-page 64  2010 Microchip Technology Inc.

If entry into Sleep mode occurs while a transmission is in progress, then the transmission is aborted. The UxTX pin is driven to logic ‘1’. Similarly, if entry into Sleep mode occurs while a reception is in progress, then the reception is aborted. The UxSTA, UxMODE, transmit and receive registers and buffers, and the UxBRG register are not affected by Sleep mode. If the WAKE bit (UxMODE<7>) is set before the device enters Sleep mode, a falling edge on the UxRX pin generates a receive interrupt. The Receive Interrupt Select mode bit (URXISEL) has no effect for this func- tion. If the receive interrupt is enabled, this wakes the device up from Sleep. The UARTEN bit must be set in order to generate a wake-up interrupt. DS70138G-page 108  2010 Microchip Technology Inc.

Write data is always in entering or leaving Sleep mode. right-justified (integer) format. The A/D module can operate during Sleep mode if the A/D clock source is set to RC (ADRC = 1). When the RC clock source is selected, the A/D module waits one instruction cycle before starting the conversion. This allows the SLEEP instruction to be executed which eliminates all digital switching noise from the conver- sion. (When the conversion sequence is complete, the DONE bit is set.)

A simplified diagram of the • Watchdog Timer (WDT) oscillator system is shown in Figure20-1. • Low-Voltage Detect • Power-Saving modes (Sleep and Idle) • Code Protection • Unit ID Locations • In-Circuit Serial Programming (ICSP) dsPIC30F devices have a Watchdog Timer which is permanently enabled via the Configuration bits or can be software controlled. It runs off its own RC oscillator for added reliability. There are two timers that offer necessary delays on power-up. One is the Oscillator Start-up Timer (OST), intended to keep the chip in Reset until the crystal oscillator is stable. The other is the Power-up Timer (PWRT) which provides a delay on power-up only, designed to keep the part in Reset while the power supply stabilizes. With these two timers on- chip, most applications need no external Reset circuitry. Sleep mode is designed to offer a very low-current Power-Down mode. The user can wake-up from Sleep through external Reset, Watchdog Timer wake-up, or through an interrupt. Several oscillator options are also made available to allow the part to fit a wide variety of applications. In the Idle mode, the clock sources are still active but the CPU is shut off. The RC oscillator option saves system cost while the LP crystal option saves power.  2010 Microchip Technology Inc. DS70138G-page 141

dsPIC30F3014/4013 23.0 ELECTRICAL CHARACTERISTICS This section provides an overview of dsPIC30F electrical characteristics. Additional information will be provided in future revisions of this document as it becomes available. For detailed information about the dsPIC30F architecture and core, refer to the “dsPIC30F Family Reference Manual” (DS70046). Absolute maximum ratings for the dsPIC30F family are listed below. Exposure to these maximum rating conditions for extended periods may affect device reliability. Functional operation of the device at these or any other conditions above the parameters indicated in the operation listings of this specification is not implied. Absolute Maximum Ratings(†) Ambient temperature under bias.............................................................................................................-40°C to +125°C Storage temperature.............................................................................................................................. -65°C to +150°C Voltage on any pin with respect to VSS (except VDD and MCLR) (Note 1).....................................-0.3V to (VDD + 0.3V) Voltage on VDD with respect to VSS ......................................................................................................... -0.3V to +5.5V Voltage on MCLR with respect to VSS .......................................................................................................0V to +13.25V Maximum current out of VSS pin...........................................................................................................................300 mA Maximum current into VDD pin (Note 2)................................................................................................................250 mA Input clamp current, IIK (VI < 0 or VI > VDD)..........................................................................................................±20 mA Output clamp current, IOK (VO < 0 or VO > VDD)...................................................................................................±20 mA Maximum output current sunk by any I/O pin..........................................................................................................25 mA Maximum output current sourced by any I/O pin....................................................................................................25 mA Maximum current sunk by all ports.......................................................................................................................200 mA Maximum current sourced by all ports (Note 2)....................................................................................................200 mA Note1: Voltage spikes below Vss at the MCLR/VPP pin, inducing currents greater than 80 mA, may cause latch-up. Thus, a series resistor of 50-100W should be used when applying a “low” level to the MCLR/VPP pin, rather than pulling this pin directly to Vss. 2: Maximum allowable current is a function of device maximum power dissipation. See Table23-4 †NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operation listings of this specification is not implied.

Parameters are for design guidance only and are not tested. 2: These parameters are characterized but not tested in manufacturing. 3: Limited by the PLL output frequency range. 4: Limited by the PLL input frequency range. 5: Instruction cycle period (TCY) equals four times the input oscillator time base period. All specified values are based on characterization data for that particular oscillator type under standard operating conditions with the device executing code. Exceeding these specified limits may result in an unstable oscillator operation and/or higher than expected current consumption. All devices are tested to operate at “min.” values with an external clock applied to the OSC1/CLKI pin. When an external clock input is used, the “Max.” cycle time limit is “DC” (no clock) for all devices. 6: Measurements are taken in EC or ERC modes. The CLKO signal is measured on the OSC2 pin. CLKO is low for the Q1-Q2 period (1/2 TCY) and high for the Q3-Q4 period (1/2 TCY). DS70138G-page 182  2010 Microchip Technology Inc.
