FT245BQ USB FIFO ( USB - Parallel ) I.C.

The FT245BQ is the lead free version of the 2

generation of FTDI鈥檚 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.

FTDI鈥檚 royalty-free VCP and D2XX drivers

eliminate the requirement for USB driver

development in most cases.

HARDWARE FEATURES

鈥?/div>

384 Byte FIFO Tx buffer / 128 Byte FIFO Rx Buffer

for high data throughput.

New Send Immediate support via SI Pin for

optimised data throughput.

Support for USB Suspend / Resume through

PWREN# and WAKEUP pins.

Support for high power USB Bus powered devices

through PWREN# pin

Adjustable RX buffer timeout

In-built support for event characters

Integrated level converter on FIFO and control

signals for interfacing to 5V and 3.3V logic

Integrated 3.3V regulator for USB IO

Integrated Power-On-Reset circuit

Integrated 6MHz 鈥?48Mhz clock multiplier PLL

USB Bulk or Isochronous data transfer modes

New Bit-Bang Mode allows the data bus to be used

as an 8 bit general purpose IO Port without the

need for MCU or other support logic.

D2XX (USB Direct Drivers + DLL S/W Interface)

APPLICATION AREAS

鈥?/div>

4.35V to 5.25V single supply operation
