FT245BL USB FIFO ( USB - Parallel ) I.C.
The FT245BL is the lead free version of the 2
nd
generation of FTDI’s popular USB FIFO I.C. This device not only
adds extra functionality to its FT8U245AM predecessor and reduces external component count, but also maintains a
high degree of pin compatibility with the original, making it easy to upgrade or cost reduce existing designs as well as
increasing the potential for using the device in new application areas.

HARDWARE FEATURES
Single Chip USB
Parallel FIFO bi-directional
Data Transfer
Transfer Data rate to 1M Byte / Sec - D2XX Drivers
Transfer Data rate to 300 Kilobyte / Sec - VCP
Drivers
Simple to interface to MCU / PLD/ FPGA logic with
a 4 wire handshake interface
Entire USB protocol handled on-chip… no USB-
specific firmware programming required
FTDI’s royalty-free VCP and D2XX drivers
eliminate the requirement for USB driver
development in most cases.
