The FT245R is a USB to parallel FIFO interface IC, with the FTDIChip-ID™ security dongle feature. In addition, asynchronous and synchronous bit bang interface modes are available. USB to parallel designs using the FT245R have been further simplified by fully integrating the external EEPROM, clock circuit and USB resistors onto the device.

Features:

  • Single chip USB to parallel FIFO bidirectional data transfer interface.
  • Entire USB protocol handled on the chip - No USB-specific firmware programming required.
  • Simple interface to MCU / PLD / FPGA logic with simple 4-wire handshake interface.
  • FTDI's royalty-free VCP and D2XX drivers eliminate the requirement for USB driver development in most cases.
  • USB FTDIChip-ID™ feature.
  • FIFO receive and transmit buffers for high data throughput.
  • Device supplied preprogrammed with unique USB serial number.
  • Integrated power-on-reset circuit.
  • Fully integrated clock - no external crystal, oscillator, or resonator required.
  • Fully integrated AVCC supply filtering - No separate AVCC pin and no external R-C filter required.
  • USB bulk transfer mode.
  • 3.3V to 5.25V Single Supply Operation.
  • Low operating and USB suspend current.
  • Low USB bandwidth consumption.
  • UHCI / OHCI / EHCI host controller compatible.
  • USB 2.0 Full Speed compatible.
  • -40°C to 85°C extended operating temperature range.
  • Available in compact Pb-free 28 Pin SSOP and QFN-32 packages (both RoHS compliant).
