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

The FTDI FT2232HQ-R Dual High Speed USB to UART/FIFO IC is a USB 2.0 integrated circuit with 480Mbps high-speed support, representing FTDI's fifth generation of USB device technology.

Overview

The FTDI FT2232HQ-R is a dual high speed USB 2.0 to multipurpose UART/FIFO integrated circuit. It can be configured for a variety of industry-standard serial or parallel interfaces, making it suitable for digital communication designs. The chip handles the USB protocol internally, removing the need for complex USB-specific firmware programming during development.

Key Features

• Dual multi-protocol synchronous serial engine (MPSSE) for USB to JTAG, I2C, SPI, and bit-bang modes
• Integrated 1.8V LDO regulator for the VCORE supply
• Integrated power-on reset (POR) function
• On-chip clock multiplier PLL generating 480MHz from a standard 12MHz input
• Two independent ports, each configurable as UART, FIFO, or MPSSE

Performance

The device supports USB 2.0 high-speed (480 Mbits/second) and full-speed (12 Mbits/second) operation. For UART applications it supports RS232, RS422, and RS485 standards with data transfer rates up to 12 Mbaud. In USB-to-parallel FIFO mode, transfer rates reach up to 8 Mbyte/sec. A fast opto-isolated serial interface option is also available. The core operates from a supply voltage range of 1.62V to 1.98V and is rated for an operating temperature range of -40°C to 85°C. Bulk data transfer uses 512-byte packets in high-speed mode, and the device is compatible with UHCI, OHCI, and EHCI host controllers.

Package

The FT2232HQ-R is supplied in a compact 64-pin QFN package. Dimensions are 3.3 (width), 1.5 (depth), and 4.3 (height), with a weight of 0.2 g.

Choose the FTDI FT2232HQ-R when a dual USB to UART/FIFO interface is required for serial, parallel, or JTAG-based communication designs.
