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.
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 – 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.
