The FT245R is a USB to parallel FIFO

interface with the following advanced

features:

• Single chip USB to parallel FIFO bidirectional 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 FIFO I/O configuration.

• Fully integrated USB termination resistors.

• Fully integrated clock generation with no external crystal required.

• Data transfer rates up to 1Mbyte / second.

• 128 byte receive buffer and 256 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.

• Unique USB FTDIChip-ID™ feature.

• Configurable FIFO interface I/O pins.

• Synchronous and asynchronous bit bang interface options.
