FT245R USB FIFO Driver

Download the FT245R USB FIFO driver here. The FT245R. Likewise it is the latest addition to FTDI’s USB FIFO interface Integrated Circuit Devices. This introduces several notable features. Notably, it serves as a USB to parallel FIFO interface and incorporates the new FTDIChip-ID™ security dongle feature. Furthermore, it offers both asynchronous and synchronous bit bang interface modes.

FT245R USB FIFO Driver

To simplify USB to parallel designs utilizing the FT245R, the device integrates the external EEPROM, clock circuit, and USB resistors directly onto the chip. This integration streamlines the design process.

In comparison to its predecessors, the FT245R introduces a new function that effectively combines two functionalities into a single chip, making it a “2-in-1” solution for certain application areas. During the manufacturing process, a unique number, known as the FTDIChip-ID, is burned into the device. This number can be read over USB and forms the foundation of a FT245R USB FIFO Driversecurity dongle, which can be used to safeguard customer application software from unauthorized copying.

The FT245R is available in compact 28-Lead SSOP and QFN-32 packages, both of which are Pb-free (RoHS compliant).

Hardware Features

The Single chip USB to parallel FIFO bidirectional data transfer interface provides numerous features and capabilities. With the entire USB protocol handled on the chip, there is no need for USB-specific firmware programming, simplifying the development process. It offers a simple 4-wire handshake interface, making it easy to interface with MCU / PLD / FPGA logic.

For data transfer, the interface supports a high rate of up to 1 Megabyte per second using D2XX Direct Drivers, while VCP Drivers enable a rate of up to 300 kilobytes per second. FTDI’s royalty-free VCP and D2XX drivers eliminate the need for USB driver development in most cases.

The interface incorporates the new USB FTDIChip-ID feature, allowing for enhanced security and protection. It includes FIFO receive and transmit buffers with buffer smoothing technology, facilitating high data throughput. The receive buffer has a size of 256 bytes, while the transmit buffer has a size of 128 bytes. An adjustable receive buffer timeout is also available.

Communication

Synchronous and asynchronous bit bang mode interface options are provided, enabling the use of the data bus as a general-purpose I/O port with the RD# and WR# strobes. In addition the interface also includes an integrated 1024-bit internal EEPROM for storing USB VID, PID, serial number, and product description strings. Each device comes pre-programmed with a unique USB serial number. Likewise see the FT232R and FT245R USB UART Drivers as well as the F600/FT601 Series Driver as well.

Additional features include support for USB suspend / resume through the PWREN# pin and Wake Up pin function. Likewise with an in-built support for event characters, and the ability to handle bus-powered, self-powered, and high-power bus-powered USB configurations. The interface incorporates a 3.3V level converter for USB I/O and offers integrated level conversion for the FIFO interface and control pins to interface with 5V – 1.8V Logic.

Interface

The interface provides true 5V / 3.3V / 2.8V / 1.8V CMOS drive output and TTL input. Additionally with an option for high I/O pin output drive. It includes integrated USB resistors and a power-on-reset circuit. The fully integrated clock eliminates the need for an external crystal, oscillator, or resonator. AVCC supply filtering is also integrated, eliminating the need for a separate AVCC pin and external R-C filter. In addition see the FT240X Full Speed USB to 8-bit FIFO driver as well as the cp2102 driver which you can also find on here.

In terms of USB functionality. Likewise the interface supports bulk transfer mode and is compatible with UHCI / OHCI / EHCI host controllers. In addition it is fully compatible with USB 2.0 Full Speed. With an extended operating temperature range of -40°C to 85°C, it is suitable for various environments. Additionally the interface is available in compact Pb-free 28 Pin SSOP and QFN-32 packages, both of which are RoHS compliant. In other issues see also the Bluetooth Driver.

Note:

  • FTDI has used Windows Update to push a malicious driver that identifies counterfeit chips
  • This driver update sends the signal NON GENUINE DEVICE FOUND! instead of functioning normally.
