FT245R USB FIFO IC
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
Unique USB FTDIChip-ID™ feature.
Configurable FIFO interface I/O pins.
Synchronous and asynchronous bit bang
