Future Technology Devices International Ltd, Unit 1, 2 Seaward Place, Centurion Business Park, Glasgow, G41 1HH, United Kingdom. Scotland Registered Number: SC136640 Copyright (c) 2010 Future Technology Devices International Limited TTL-232R TTL TO USB SERIAL CONVERTER RANGE OF CABLES Datasheet Version 2.02 Clearance No.: FTDI# 53 Document Reference No.: FT_000054 1 Description The TTL-232R cables are a family of USB to TTL serial UART converter cables incorporating FTDIs 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 TTL level serial interface to USB. Each TTL-232R 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, DS_FT232R, is available at http://www.ftdichip.com. The other end of the cable comes with a selection of different connectors supporting various applications - see Table 1.1 Cables are FCC, CE, RoHS compliant and are available at TTL levels of +5V and +3.3V. Cables are available with either a 6-way SIL,0.1" pitch connector, a 3.5mm Audio Jack, an 8 way, keyed 2mm pitch connector (intended for use with VMUSIC2 or VDRIVE2) or bare, tinned wire ended connections (see Table 1.1) The USB side of the cable is USB powered and 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-IDTM, 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-232R 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 Various Connector Options TTY TTL-232R USB Wire Ended 3mm Audio Jack 6 way, 0.1" Single In Line connector 8 way, Keyed,2mm, Single In Line connector VCP Virtual COM Port Various Connector Options Wire Ended TTY D2XX 3mm Audio Jack USB 6 way, 0.1" Single In Line connector 8 way, Keyed,2mm, Single In Line connector Software application access to USB via D2XX Figure 1.1 Using the TTL-232R Cable DLL Copyright (c) 2010 Future Technology Devices International Limited 1 TTL-232R TTL TO USB SERIAL CONVERTER RANGE OF CABLES Datasheet Version 2.02 Clearance No.: FTDI# 53 Document Reference No.: FT_000054 1.1 Available Cables and Part Numbers The following Table 1.1 gives details of the available TTL-232R cables.

Appendix A - Cable EEPROM Configuration. 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 FT_PROG, 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 70A. (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-232R 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-232R cables (RXD, TXD, RTS#, and CTS#) can be configured to use the FT232Rs 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 a 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-IDTM. The FT232R includes the new FTDIChip-IDTM security dongle feature. This FTDIChip-IDTM 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-232R cables as a dongle for software licensing. Further to this, a renewable license scheme can be implemented based on the FTDIChip-IDTM 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-IDTM 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-232R cables are FCC and CE certified. Extended Operating Temperature Range - The TTL-232R cables are capable of operating over an extended temperature range of -40 to +85 C thus allowing them to be used in automotive or industrial applications.

This FT232R device contains an EEPROM which contains the USB configuration descriptors for that device. When the cable is plugged into a PC or a USB reset is performed, the PC will read these descriptors. The default values stored into the internal EEPROM are defined in Table 0.1 Parameter USB Vendor ID (VID) USB Product UD (PID) Serial Number Enabled? Serial Number Value 0403h 6001h Yes A unique serial number is generated and programmed into See Note the EEPROM during device final test. Enabling this option will make the device pull down on the Pull down I/O Pins in USB Suspend Manufacturer Name Disabled UART interface lines when the power is shut off (PWREN# is high). FTDI Product description depends on the cable. The following lists the Product description for each different cable. TTL-232R-5V TTL-232R-3V3 Product Description See note TTL-232R-5V-AJ TTL-232R-AJ-3V3 TTL-232R-5V-WE TTL-232R-3V3-WE TTL-232R-3V3-2MM = USB <-> Serial Cable Max Bus Power Current Power Source Device Type 90mA Bus Powered FT232R Returns USB 2.0 device description to the host. Note: The device is be a USB 2.0 Full Speed device USB Version 0200 (12Mb/s) as opposed to a USB 2.0 High Speed device (480Mb/s). Remote Wake Up High Current I/Os Disabled Enables the high drive level on the UART and CBUS I/O Enabled pins.

FT_PROG can be downloaded from the www.ftdichip.com. Version 2.8a or later is required for the FT232R chip. Users who do not have their own USB Vendor ID but who would like to use a unique Product ID in their design can apply to FTDI for a free block of unique PIDs. Contact FTDI support for this service.
