FT4232H 概述

The FT4232H is a USB 2.0 Hi-Speed (480Mb/s) to UART IC. It has the capability of being configured in a variety of industry standard serial or parallel interfaces.

The FT4232H features 4 UARTs. Two of these have an option to independently configure an MPSSE engine, this allows the FT4232H to operate as two UART/Bit-Bang ports plus two MPSSE engines used to emulate JTAG, SPI, I2C, Bit-bang or other synchronous serial modes.

The FT4232H is available in Pb-free (RoHS compliant) 64-pin LQFP and QFN packages.

FT4232H 特性

  • Single chip USB to quad serial 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.
  • Two Multi-Protocol Synchronous Serial Engine (MPSSE) on channel A and channel B, to simplify synchronous serial protocol (USB to JTAG, I2C, SPI or bit-bang) design.
  • RS232/RS422/RS485 UART Transfer Data Rate up to 12Mbaud. (RS232 Data Rate limited by external level shifter).
  • Support for USB suspend and resume conditions via PWREN#, SUSPEND# and RI# pins.
  • Highly integrated design includes +1.8V LDO regulator for VCORE, integrated POR function and on chip clock multiplier PLL (12MHz – 480MHz).
  • FTDI FT232B style, asynchronous serial UART interface option with full hardware handshaking and modem interface signals.
  • UART Interface supports 7/8 bit data, 1/2 stop bits, and Odd/Even/Mark/Space/No Parity.
  • Auto-transmit enable control for RS485 serial applications using TXDEN pin.

  • Low operating and USB suspend current.
  • Configurable I/O drive strength (4,8,12 or 16mA) and slew rate
  • Supports bus powered, self powered and high-power bus powered USB configurations.
  • UHCI/OHCI/EHCI host controller compatible.
  • USB Bulk data transfer mode (512 byte packets in Hi-Speed mode).
  • Dedicated Windows DLLs available for USB to JTAG, USB to SPI, and USB to I2C applications.
  • +1.8V (chip core) and +3.3V I/O interfacing (+5V Tolerant).
  • Extended -40ºC to 85ºC industrial operating temperature range.
  • Compact 64-LD Lead Free LQFP or LQFN package.
