TTL to USB Serial Converter Generic Cables Datasheet Version 1.5 Document Reference No.: FT_000188 Clearance No.: FTDI# 129 1 Introduction The TTL-232RG generic cables are a family of USB to TTL serial UART converter cables incorporating FTDI’s FT232RQ USB to Serial UART interface IC device which handles all the USB signalling and protocols. The cables provide a fast, simple way to connect devices with a logic level serial interface to USB. Each TTL-232RG generic cable contains a small internal electronic circuit board, utilising the FT232R, which is encapsulated into the USB connector end of the cable. The FT232R datasheet is available at http://www.ftdichip.com/Support/Documents/DataSheets.htm. The other end of the cable is wire ended. The cables can be used for “TTL” or interface logic over a range to voltage levels. Cables are FCC, CE, and RoHS compliant at TTL levels of + 5V to + 1.8V. The USB side of the cable is USB powered and is USB 2.0 full speed compatible. Each cable is 1.8m long and supports a data transfer rate up to 3 Mbaud. Each cable supports the FTDIChip-ID™, with a unique USB serial number programmed into the FT232R. This feature can be used to create a security or password protected file transfer access using the cable. Further information and examples on this feature are available at http://www.ftdichip.com under FTDIChip-ID Projects. The TTL-232RG generic cables require USB drivers, available free from http://www.ftdichip.com, which are used to make the FT232R in the cable appear as a virtual COM port (VCP). This then allows the user to communicate with the USB interface via a standard PC serial emulation port (for example TTY). Another FTDI USB driver, the D2XX driver, can also be used with application software to directly access the FT232R on the cable though a DLL. This is illustrated in the Figure 1.1 Figure 1.1 - Using the TTL-232RG Generic Cable Copyright © Future Technology Devices International Limited 2

Note 2: Any regulator from 1.8V to 5V can be used. 1.8V and 3.3V versions are standard products. Others values are customized at the factory. Note 3: Any INPUT voltage can be supplied by the customer from 1.8V (min value of VCCIO) to +5.25V (Max value of VCCIO) Note 4: The VCC power output signal (RED wire) is 3.3V. The source of 3.3V is the FT232R regulator output, which is switched onto the power output signal. Note 5: The VCC power output signal (RED wire) is 3.3V. The source of 3.3V is on board 3.3V regulator output, which is switched onto the power output signal Note 6: The VCC power output signal (RED wire) is 1.8V. The source of 1.8V is on board 1.8V regulator output, which is switched onto the power output signal Copyright © Future Technology Devices International Limited 3

TTL to USB Serial Converter Generic Cables Datasheet Version 1.5 Document Reference No.: FT_000188 Clearance No.: FTDI# 129 Note 7: The VCC power output signal (RED wire) is 5.0V. The source of 5.0V is the USB VBUS input, which is switched onto the power output signal. At the time of releasing these cables, this cable was not available. It will become available at a later date. Please contact FTDI Sales for further information. Note 8: The VCC power input signal (RED wire) is an output from customer electronics, an input to the cable. This value=i/pV. The source of i/pV is from customer’s interface logic and this is used to drive the VCCIO and hence the signal levels on the wires. This makes the generic cable customisable to whatever output voltage the customer interface is operating at 1.8V to 5.25V range. FTDI supports customised end connector designs. For more information, please contact your local FTDI sales office (see end of datasheet for contact details). 1.2 Certifications The FTDI TTL-232RG range of generic cables is fully RoHS compliant and FCC/CE approved.

TTL to USB Serial Converter Generic Cables Datasheet Version 1.5 Document Reference No.: FT_000188 Clearance No.: FTDI# 129 3 FT232R features applicable to TTL-232RG generic cables The TTL-232RG generic cables use FTDI’s FT232RQ USB to serial IC device. This section summarises the key features of the FT232RQ which apply to the TTL-232RG USB to serial TTL converter cables. For further details, and a full features and enhancements description consult the FT232R datasheet, this is available from http://www.ftdichip.com. Internal EEPROM. The internal EEPROM in each cable is used to store USB Vendor ID (VID), Product ID (PID), device serial number, product description string and various other USB configuration descriptors. Each cable is supplied with the internal EEPROM pre-programmed as described in Appendix AError! Reference source not found.. A user area of the internal EEPROM is available to system designers to allow storing additional data. The internal EEPROM descriptors can be programmed in circuit, over USB without any additional voltage requirement. It can be programmed using the FTDI utility software called MPROG, which can be downloaded from FTDI Utilities on the FTDI website (www.ftdichip.com). Lower Operating and Suspend Current. The FT232R has a low 15mA operating supply current and a very low USB suspend current of approximately 70μA. (Note that during suspend mode, the current drawn by application should not exceed 2.5mA to remain USB compliant) Low USB Bandwidth Consumption. The USB interface of the FT232R, and therefore the TTL-232RG cables has been designed to use as little as possible of the total USB bandwidth available from the USB host controller. High Output Drive Option. The UART interface I/O pins on the TTL-232RG cables (RXD, TXD, RTS#, and CTS#) can be configured to use the FT232R’s high output drive option. This option allows the FT232R I/O pins to drive up to three times the standard signal drive level. This allows multiple devices to be driven, or devices that require greater signal drive strength to be interfaced to the cables. This option is enabled in the internal EEPROM. UART Pin Signal Inversion. The sense of each of the eight UART signals can be individually inverted by configuring options in the internal EEPROM. For example CTS# (active low) can be changed to CTS (active high), or TXD can be changed to TXD#. FTDIChip-ID™. The FT232R includes the FTDIChip-ID™ security dongle feature. This FTDIChip-ID™ feature allows a unique number to be burnt into each cable during manufacture. This number cannot be reprogrammed. This number is only readable over USB can be used to form the basis of a security dongle which can be used to protect any customer application software being copied. This allows the possibility of using the TTL-232RG cables as a dongle for software licensing. Further to this, a renewable license scheme can be implemented based on the FTDIChip-ID™ number when encrypted with other information. This encrypted number can be stored in the user area of the FT232R internal EEPROM, and can be decrypted, then compared with the protected FTDIChip-ID™ to verify that a license is valid. Web based applications can be used to maintain product licensing this way. An application note, AN232R-02, available from FTDI website (www.ftdichip.com) describes this feature. Improved EMI Performance. The TTL-232RG cables are FCC and CE certified. Extended Operating Temperature Range - The TTL-232RG generic cables are capable of operating over an extended temperature range of -40º to +85º C thus allowing them to be used in automotive or industrial applications.
