FT232HL-REEL

The FT232H is a single channel 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 FT232H requires USB device drivers (listed below), available free from http://www.ftdichip.com, to
operate. The VCP version of the driver creates a Virtual COM Port allowing legacy serial port applications
to operate over USB e.g. serial emulator application TTY. Another FTDI USB driver, the D2XX driver, can
also be used with application software to directly access the FT232H through a DLL.

    SPECIFICATION

    • Single channel USB to serial / parallel ports
    with a variety of configurations.
    • Entire USB protocol handled on the chip. No
    USB specific firmware programming required.
    • USB 2.0 Hi-Speed (480Mbits/Second) and Full
    Speed (12Mbits/Second) compatible.
    • Multi-Protocol Synchronous Serial Engine
    (MPSSE) to simplify synchronous serial protocol
    (USB to JTAG, I2C, SPI (MASTER) or bit-bang)
    design.
    • UART transfer data rate up to 12Mbaud.
    (RS232 Data Rate limited by external level
    shifter).
    • USB to asynchronous 245 FIFO mode for
    transfer data rate up to 8 Mbyte/Sec.
    • USB to synchronous 245 parallel FIFO mode for
    transfers up to 40 Mbytes/Sec
    • Supports a proprietary half duplex FT1248
    interface with a configurable width, bidirectional data bus (1, 2, 4 or 8 bits wide).
    • CPU-style FIFO interface mode simplifies CPU
    interface design.
    • Fast serial interface option.
    • FTDI’s royalty-free Virtual Com Port (VCP) and
    Direct (D2XX) drivers eliminate the
    requirement for USB driver development in
    most cases.
    • Adjustable receive buffer timeout.
    • Option for transmit and receive LED drive
    signals.
    • Bit-bang Mode interface option with RD# and
    WR# strobes
    • Highly integrated design includes 5V to
    3.3/+1.8V LDO regulator for VCORE, integrated
    POR function
    • Asynchronous serial UART interface option with
    full hardware handshaking and modem
    interface signals.
    • Fully assisted hardware or X-On / X-Off
    software handshaking.
    • 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 the TXDEN pin.
    • Operational mode configuration and USB
    Description strings configurable in external
    EEPROM over the USB interface.
    • Configurable I/O drives strength (4, 8, 12 or
    16mA) and slew rate.
    • Low operating and USB suspend current.
    • Supports self-powered, bus powered and highpower bus powered USB configurations.
    • 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 48-pin Lead Free LQFP or QFN
    package
    • Configurable ACBUS I/O pins.
