FT245RL Electronic IC Chips single integrated circuit USB FIFO IC

FT245R USB FIFO IC - Single chip USB to parallel FIFO bidirectional data transfer interface

The FT245R is a USB to parallel FIFO interface with the following advanced features:

• Single chip USB to parallel FIFO bidirectional data transfer interface.
• Entire USB protocol handled on the chip. No USB specific firmware programming required.
• Fully integrated 1024 bit EEPROM storing device descriptors and FIFO I/O configuration.
• Fully integrated USB termination resistors.
• Fully integrated clock generation with no external crystal required.

• Data transfer rates up to 1Mbyte / second.
• 128 byte receive buffer and 256 byte transmit buffer utilising buffer smoothing technology to allow for high data throughput.
• FTDI‟s royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases.
• Unique USB FTDIChip-ID™ feature.
• Configurable FIFO interface I/O pins.

• Synchronous and asynchronous bit bang interface options.
• Device supplied pre-programmed with unique USB serial number.
• Supports bus powered, self powered and high-power bus powered USB configurations.
• Integrated +3.3V level converter for USB I/O.
• Integrated level converter on FIFO interface for interfacing to external logic running at between +1.8V and +5V.

• True 5V/3.3V/2.8V/1.8V CMOS drive output and TTL input.
• Configurable I/O pin output drive strength.
• Integrated power-on-reset circuit.
• Fully integrated AVCC supply filtering - no external filtering required.
• +3.3V (using external oscillator) to +5.25V (using internal oscillator) 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.
