FT2232HL Dual-Channel USB to UART / FIFO / SPI / I2C / JTAG Interface Module

Overview 📝

The FT2232HL is a powerful dual-channel USB 2.0 High-Speed (480 Mb/s) to multipurpose serial/parallel interface IC. It handles the entire USB protocol directly on-chip without requiring any specialized firmware programming. Equipped with dual Multi-Protocol Synchronous Serial Engines (MPSSE), each channel can be independently configured for flexible protocols such as UART, FIFO, JTAG, SPI, or I²C.

Key Features ✨

• Dual Independent Channels: Configure each channel separately for different modes including UART, serial FIFO, JTAG, SPI, or I²C.

• High-Speed USB 2.0 Support: Operates at up to 480 Mb/s in high-speed mode and 12 Mb/s in full-speed mode.

• MPSSE Support: Dual Multi-Protocol Synchronous Serial Engines simplify custom synchronous serial designs (JTAG, SPI, I²C).

• Adjustable Baud Rates & Buffers: UART data rates up to 12 Mbaud (RS232/RS422/RS485) and parallel FIFO transfer rates up to 8 Mbyte/s.

• Driver Ecosystem: Fully compatible with royalty-free Virtual COM Port (VCP) and D2XX direct drivers across Windows, Linux, and macOS.
