The FTDI IC is high quality! • 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 USBspecific 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.
• 4.35V to 5.25V single supply operation
• UHCI / OHCI / EHCI host controller compatible
• USB 1.1 and USB 2.0 compatible
