The FT231X is a USB to full handshake serial UART interface device which simplifies USB implementations
and reduces external component count by fully integrating an MTP memory, and an integrated clock
circuit which requires no external crystal. It has been designed to operate efficiently with USB host
controllers by using as little bandwidth as possible when compared to the total USB bandwidth available.

The FT231X is a USB to serial UART interface
with full modem control and the following
advanced features:
 Single chip USB to asynchronous serial data
transfer interface.
 Entire USB protocol handled on the chip. No
USB specific firmware programming required.
 Fully integrated 2048 byte multi-timeprogrammable (MTP) memory, storing device
descriptors and CBUS I/O configuration.
 Fully integrated clock generation with no
external crystal required plus optional clock
output selection enabling a glue-less interface
to external MCU or FPGA.
 Data transfer rates from 300 baud to 3 Mbaud
(RS422, RS485, and RS232) at TTL levels.
 512 byte receive buffer and 512 byte transmit
buffer utilising buffer smoothing technology to
allow for high data throughput.
 FTDI’s royalty-free Virtual Com Port (VCP)
and Direct (D2XX) drivers eliminate the
requirement for USB driver development in
most cases.
 Configurable CBUS I/O pins.
 Transmit and receive LED drive signals.
 UART interface support for 7 or 8 data bits, 1
or 2 stop bits and odd / even / mark / space
no parity
 Synchronous and asynchronous bit bang
interface options with RD# and WR# strobes.
 USB Battery Charger Detection. Allows for USB
peripheral devices to detect the presence of a
higher power source to enable improved
charging.
 Device supplied pre-programmed with unique
USB serial number.
 USB Power Configurations; supports buspowered, self-powered and bus-powered with
power switching
 Integrated +3.3V level converter for USB I/O.
 True 3.3V CMOS drive output and TTL input;
Operates down to 1V8 with external pull-ups.
Tolerant of 5V input.
 Configurable I/O pin output drive strength; 4
mA(min) and 16 mA(max).
 Integrated power-on-reset circuit.
 Fully integrated AVCC supply filtering - no
external filtering required.
 UART signal inversion option.
 + 5V Single Supply Operation.
 Internal 3V3/1V8 LDO regulators
Low operating and USB suspend current; 8mA
(active-typ) and 125uA (suspend-typ).
 UHCI/OHCI/EHCI host controller compatible
 USB 2.0 Full Speed capable.
 Extended operating temperature range; -40 to
85⁰C.
 Available in compact, Pb-free, 20 Pin SSOP and
QFN packages (both RoHS compliant).
