Visão Geral

Description

The FT4222HQ-D-R is a high-speed USB 2.0 to quad SPI/I²C bridge IC from FTDI. It enables seamless communication between a USB host and SPI/I²C peripherals, supporting up to 40 MHz SPI and 1 MHz I²C speeds.
Key features:
- Quad SPI (1x master, 4x slave) or single I²C master modes.
- USB 2.0 High-Speed (480 Mbps) with a 56-pin QFN package.
- Supports GPIOs for additional control.
- Works with FTDI’s D2XX and LibFT4222 drivers for easy integration.
Applications include embedded systems, industrial control, and IoT devices requiring fast USB-to-SPI/I²C conversion. The "-R" suffix indicates tape-and-reel packaging for automated assembly.
For more details, refer to FTDI’s datasheet and application notes.
