FT232R
FT232R is USB UART manufactured by FTDI.
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 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.
