Overview

The FT245RNQ-REEL is a USB to parallel FIFO interface IC designed to simplify the implementation of USB connectivity in embedded systems. It handles the entire USB protocol on-chip, requiring no USB-specific firmware programming, and presents data to the system MCU via a simple 8-bit wide bidirectional data bus.

Why Choose This Part

This IC integrates an internal oscillator and EEPROM, eliminating the need for an external crystal and reducing BOM count. It provides a straightforward 128-byte receive buffer and 384-byte transmit buffer to smooth out data throughput, while operating over a wide temperature range of -40C to 85C.

Applications

Legacy Peripheral Upgrades
Replacing older Centronics or parallel port interfaces with modern USB connectivity in legacy industrial equipment.
MCU Data Offloading
Rapidly transferring large blocks of data from an FPGA or microcontroller to a PC host without the overhead of bit-banging UART.
USB Hardware Dongles
Creating security keys or software protection dongles that utilize the internal unique USB ID.
Data Acquisition Systems
Streaming high-bandwidth sensor data over USB to a host PC for real-time analysis and logging.

Getting Started

Engineers can begin development using the UM245R evaluation module or by downloading the Royalty-Free D2XX drivers from FTDI. The device is configured via the FT_PROG utility to set internal EEPROM parameters such as VID, PID, and power descriptors.

Also Consider

FT2232HL-REEL FTDI - Offers dual-channel capabilities and supports High Speed USB (480Mbps) for applications requiring higher bandwidth.
