TTL-232R-3V3

USB to TTL Serial

Converter Cable

The TTL-232R-3V3 is a USB to TTL serial converter cable incorporating FTDI’s FT232RQ USB - Serial UART

interface IC device, the latest device to be added to FTDI’s range of USB UART interface Integrated Circuit Devices. It

is designed to allow for a fast, simple way to connect devices with a TTL level serial interface to USB.

The FT232RQ chip used by the TTL-232R-3V3 is housed within the USB ‘A’ connector. A 1.8 meter (6 foot) cable is

terminated with a 6 way 0.1” pitch header socket which provides access to the transmit (Tx), receive (Rx), RTS#, and

CTS#, as well as VCC (5V out) and GND.

The FT232R is a USB to serial UART interface with optional clock generator output, and the new FTDIChip-ID™

security dongle feature. In addition, asynchronous and synchronous bit bang interface modes are available. USB to

serial interface designs using the FT232R have been further simpliﬁ ed by fully integrating the external EEPROM, clock

circuit and USB resistors onto the device.
