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 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-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 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 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-ID™. The FT232R includes the new 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-232R 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-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 -40º to +85º C thus allowing them to be used in automotive or industrial
applications.
