1.1 Hardware Features
UC232R Converter Cable provides USB to RS232
(DB9) interface.
FCC and CE Class B Approval
Full design ?les available from FTDI website .
FT232RL provides single chip USB to
asynchronous serial data transfer interface.
Entire USB protocol handled on the FT232RL chip
- No USB-speci?c ?rmware programming required.
UART interface support for 7 or 8 data bits, 1 or 2
stop bits and odd / even / mark / space / no parity.
Fully assisted hardware or X-On / X-Off software
handshaking.
Data transfer rates from 300 baud to 250 kilobaud
at RS232 levels.
FTDI’s royalty-free VCP and D2XX drivers
eliminate the requirement for USB driver
development in most cases.
In-built support for event characters and line break
condition.
New USB FTDIChip-ID? feature.
FIFO receive and transmit buffers for high data
throughput.
Adjustable receive buffer timeout.
Integrated 1024 bit internal EEPROM for storing
USB VID, PID, serial number and product
description strings.
