FT232R USB UART IC
Datasheet
The FT232R is a USB to serial UART interface
with the following advanced features: FIFO receives and transmits buffers for high
data throughput. Single chip USB to asynchronous serial data
transfer interface. Synchronous and asynchronous bit bang
interface options with RD# and WR# strobes. Entire USB protocol handled on the chip. No
USB specific firmware programming required. Device supplied pre-programmed with unique
USB serial number. Fully integrated 1024 bit EEPROM storing
device descriptors and CBUS I/O configuration. Supports bus powered, self-powered and highpower bus powered USB configurations. Fully integrated USB termination resistors. Integrated +3.3V level converter for USB I/O. Fully integrated clock generation with no
external crystal required plus optional clock
output selection enabling a glue-less interface
to external MCU or FPGA. Integrated level converter on UART and CBUS
for interfacing to between +1.8V and +5V
logic. Data transfer rates from 300 baud to 3 Mbaud
(RS422, RS485, RS232) at TTL levels. True 5V/3.3V/2.8V/1.8V CMOS drive output
and TTL input. Configurable I/O pin output drive strength. 128 byte receive buffer and 256 byte transmit
buffer utilising buffer smoothing technology to
allow for high data throughput. Integrated power-on-reset circuit. Fully integrated AVCC supply filtering -no
