Introduction

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.

Features

• 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, I²Cν, 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/0 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.
