FT2232H 概述

The FT2232H is FTDI's 5th generation of USB devices. The FT2232H is a USB 2.0 Hi-Speed (480Mb/s) to UART/FIFO IC. It has the capability of being configured in a variety of industry standard serial or parallel interfaces.

The FT2232H has two multi-protocol synchronous serial engines (MPSSEs) which allow for communication using JTAG, I2C and SPI on two channels simultaneously.

The FT2232H is available in Pb-free (RoHS compliant) 64-pin LQFP and QFN packages.

FT2232H 特性

  • Single chip USB to dual serial / parallel ports with a variety of configurations
  • Entire USB protocol handled on the chip. No USB specific firmware programming required.
  • USB 2.0 High Speed (480Mbits/second) and Full Speed (12Mbits/second) compatible.
  • Dual Multi-Protocol Synchronous Serial Engine (MPSSE) to simplify synchronous serial protocol (USB to JTAG, I2C, SPI or bit-bang) design.
  • Dual independent UART or FIFO ports configurable using MPSSEs.
  • RS232/RS422/RS485 UART Transfer Data Rate up to 12Mbaud. (RS232 Data Rate limited by external level shifter).
  • CPU-style FIFO interface mode simplifies CPU interface design.
  • UART Interface supports 7/8 bit data, 1/2 stop bits, and Odd/Even/Mark/Space/No Parity.
  • Operational configuration mode and USB Description strings configurable in external EEPROM over the USB interface.

  • UHCI/OHCI/EHCI host controller compatible.
  • USB Bulk data transfer mode (512 byte packets in Hi-Speed mode).
  • +1.8V (chip core) and +3.3V I/O interfacing (+5V Tolerant).
  • Extended -40°C to 85°C industrial operating temperature range.
  • Compact 64-LD Lead Free LQFP or LQFN package.
  • +3.3V single supply operating voltage range.
