FT232R USB UART IC
The FT232R is a USB to serial UART ^
interface with 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 1024 bit EEPROM storing
device descriptors and CBUS I/O configuration. ^
 Fully integrated USB termination resistors.

 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, RS232) at TTL levels.

 128 byte receive buffer and 256 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.

 Unique USB FTDIChip-ID™ feature.

 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

FIFO receives and transmits buffers for high
data throughput.
Synchronous and asynchronous bit bang
interface options with RD# and WR# strobes.
Device supplied pre-programmed with unique
USB serial number.
Supports bus powered, self-powered and high-
power bus powered USB configurations.
Integrated +3.3V level converter for USB I/O.
Integrated level converter on UART and CBUS
for interfacing to between +1.8V and +5V
logic.
True 5V/3.3V/2.8V/1.8V CMOS drive output
and TTL input.
Configurable I/O pin output drive strength.
Integrated power-on-reset circuit.
Fully integrated AVCC supply filtering - no
external filtering required.
UART signal inversion option.
