FTDI FT2232HQ-R Dual High Speed USB to UART/FIFO IC, 480Mbps, 64-Pin QFN

The FTDI FT2232HQ-R is a dual high speed USB 2.0 to multipurpose UART/FIFO integrated circuit, representing FTDI's fifth generation of USB device technology. This highly versatile IC can be configured for a variety of industry-standard serial or parallel interfaces, making it an essential component for modern digital communication designs. The chip handles the entire USB protocol internally, eliminating the need for complex USB-specific firmware programming and significantly speeding up development time.

A key feature is its dual multi-protocol synchronous serial engine (MPSSE), which simplifies the design of synchronous serial protocols such as USB to JTAG, I2C, SPI, or bit-bang modes. The highly integrated design includes a 1.8V LDO regulator for the VCORE supply, an integrated power-on reset (POR) function, and an on-chip clock multiplier PLL capable of generating a 480MHz clock from a standard 12MHz input.

Core Specifications & Performance

The device is fully compatible with USB 2.0 high-speed (480 Mbits/second) and full-speed (12 Mbits/second) operations. It features two completely independent ports, each configurable as a UART, FIFO, or MPSSE interface with its own baud rate generator. For UART applications, it supports RS232, RS422, and RS485 standards with data transfer rates up to 12 Mbaud. In USB-to-parallel FIFO mode, it achieves transfer rates up to 8 Mbyte/sec, and it offers a fast opto-isolated serial interface option for added flexibility in industrial environments.

The core operates from a low supply voltage range of 1.62V to 1.98V and is built to withstand an extended operating temperature range from -40°C to 85°C, ensuring reliability in demanding conditions. It utilises efficient USB bulk data transfer mode with 512-byte packets in high-speed mode and is compatible with UHCI, OHCI, and EHCI host controllers.
