Single chip USB to UART synchronous serial
data transfer interface
Entire USB protocol handled on the chip –
No USB-specific firmware 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 3
Megabaud (RS422 / RS485 and at TTL
levels) and 300 baud to 1 Megabaud
(RS232).
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.
USB FTDIChip-ID™ feature.
Configurable CBUS I/O pins.

Support for USB suspend and resume.
Integrated 1024 bit internal EEPROM for
storing USB VID, PID, serial number and
product description strings, and CBUS I/O
configuration.
Device supplied preprogrammed with
unique USB serial number.
Support for bus powered, self powered, and
high-power bus powered USB
configurations.
