The difference between the two cables is that the TTL-232R-5V operates at +5V levels (signals and power supply) and the TTL-232R-3V3 operates at +3.3V levels (signals only, VCC= +5V). TTL-232R-5V and TTL-232R-3V3 Cables The TTL-232R-5V and TTL-232R-3V3 cables are both terminated way, 0.1”, Single-In-Line (SIL) connector. The UART interface I/O pins on the TTL-232R cables (RXD, TXD, RTS#, and CTS#) can be configured to use the FT232R‟. 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. USB compliant) Low USB Bandwidth Consumption.

For further details, and a full features and enhancements description consult the FT232R datasheet, this is available from This section summarises the key features of the FT232RQ which apply to the TTL-232R USB to serial TTL converter cables. The TTL-232R cables use FTDI‟s FT232RQ USB to serial IC device. +5V or +3.3V output allows external logic to be powered from the USB port.

TTL-232R 1.2 Certifications FTDI TTL-232R range of cables are fully RoHs compliant as well as CE and FCC certified (with the exception of the TTL-232R-XX-WE cables which have not yet completed FCC and CE testing). number for clarity Copyright © 2010 Future Technology Devices International Limited TTL TO USB SERIAL CONVERTER RANGE OF CABLES Datasheet Version 2.02 End Connector* 6 pin SIL, 0.1” pitch 6 pin SIL, 0.1” pitch.
These cables are identical to cables which do not have the “5V” in the part number. 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 cables provide a fast, simple way to connect devices with a TTL level serial interface to USB. FT232RQ USB to Serial UART interface IC device which handles all the USB signalling and protocols.
