FT245RQ

# Single chip USB to parallel FIFO bidirectional data transfer interface.
# Entire USB protocol handled on the chip - No USB-specific firmware programming required.
# Simple interface to MCU / PLD / FPGA logic with simple 4-wire handshake interface.
# Data transfer rate to 1 Megabyte / second - D2XX Direct Drivers.
# Data transfer rate to 300 kilobyte / second - VCP Drivers.
# FTDI?s royalty-free VCP and D2XX drivers eliminate the requirement for
USB driver development in most cases.
# New USB FTDIChip-ID? feature.
# FIFO receive and transmit buffers for high data throughput.
# 256 Byte receive buffer and 128 Byte transmit buffer utilising buffer
smoothing technology to allow for high data throughput.
# Adjustable receive buffer timeout.
# Synchronous and asynchronous bit bang mode interface options with RD
# and WR# strobes allow the data bus to be used as a general purpose I/O port.
# Integrated 1024 Byte internal EEPROM for storing USB VID, PID, serial number and product description strings.
