Future Technology

Single chip USB to asynchronous serial data

transfer interface.

Entire USB protocol handled on the chip. No

USB specific firmware programming required.

Fully

programmable (MTP) memory, storing device

descriptors and CBUS I/O configuration.

Fully integrated clock generation with no

external crystal required plus optional clock

output selection enabling glue-less interface

to external MCU or FPGA.

Data transfer rates from 300 baud to 3 Mbaud

(RS422, RS485, and RS232 ) at TTL levels.

512 byte receive buffer and 512 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.

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

Synchronous

interface options with RD# and WR# strobes.
