相关介绍

FT245B 規格書下載


  • Single Chip USB <=> parallel FIFO bi-directional data transfer
  • Data transfer rate of up to 1M Byte/second (D2XX drivers)
  • Data transfer rate of up to 300K Byte/second (VCP drivers)
  • Simple to interface to MCU/PLD/FPGA logic with a 4-wire handshaking 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
  • Built-in 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
  • UHC/OHCI/EHCI host controller compatible
  • USB 1.1 and USB 2.0 compatible
  • USB VID, PID , serial number and product description strings in external EEPROM
  • EEPROM programmable on-board via USB
  • Compact 32-LD LQFP or QFN-32 package
  • Available as a Lead-free device (FT245BL and FT245BQ) compliant to EU directive 2002/95/EG RoHS
