FT4232H QUAD HIGH SPEED USB TO MULTIPURPOSE UART/MPSSE IC Datasheet Version 2.6 Document No.: FT 000060 Clearance No.: FTDI 78 Future Technology Devices International Ltd FT4232H Quad High Speed USB to Multipurpose UART/MPSSE IC Highly integrated design includes +1.8V LDO th The FT4232H is FTDIs 5 generation of USB devices. regulator for VCORE, integrated POR function The FT4232H is a USB 2.0 High Speed (480Mb/s) to and on chip clock multiplier PLL (12MHz UART/MPSSE ICs. The device features 4 UARTs. Two 480MHz). of these have an option to independently configure FTDI FT232B style, asynchronous serial UART an MPSSE engine. This allows the FT4232H to interface option with full hardware handshaking operate as two UART/Bit-Bang ports plus two MPSSE and modem interface signals. 2 engines used to emulate JTAG, SPI, I C, Bit-bang or Fully assisted hardware or X-On / X-Off software other synchronous serial modes. The FT4232H has handshaking. the following advanced features: UART Interface supports 7/8 bit data, 1/2 stop bits, and Odd/Even/Mark/Space/No Parity. Single chip USB to quad serial ports with a Auto-transmit enable control for RS485 serial variety of configurations. applications using TXDEN pin. Entire USB protocol handled on the chip. No USB Operational configuration mode and USB specific firmware programming required. Description strings configurable in external USB 2.0 High Speed (480Mbits/Second) and Full EEPROM over the USB interface. Speed (12Mbits/Second) compatible. Low operating and USB suspend current. Two Multi-Protocol Synchronous Serial Engine Configurable I/O drive strength (4, 8, 12 or (MPSSE) on channel A and channel B, to simplify 2 16mA) and slew rate. synchronous serial protocol (USB to JTAG, I C, Supports bus powered, self-powered and high- SPI or bit-bang) design. power bus powered USB configurations. Independent Baud rate generators. UHCI/OHCI/EHCI host controller compatible. RS232/RS422/RS485 UART Transfer Data Rate USB Bulk data transfer mode (512 byte packets up to 12Mbaud. (RS232 Data Rate limited by in High Speed mode). external level shifter). Dedicated Windows DLLs available for USB to FTDIs royalty-free Virtual Com Port (VCP) and 2 JTAG, USB to SPI, and USB to I C applications. Direct (D2XX) drivers eliminate the requirement +1.8V (chip core) and +3.3V I/O interfacing for USB driver development in most cases. (+5V Tolerant). Optional traffic TX/RX indicators can be added Extended -40C to 85C industrial operating with LEDs and an external 74HC595 shift temperature range. register. Compact 64-LD Lead Free LQFP or QFN package Adjustable receive buffer timeout. Available in compact Pb-free 56 Pin VQFN Support for USB suspend and resume conditions packages (RoHS compliant) via PWREN , SUSPEND and RI pins. +3.3V single supply operating voltage range.
