Future Technology Devices International has further strengthened its range of USB interface IC products with the release of the FT232H USB2.0 high-speed device.

This single-channel USB to UART/FIFO interface can be configured via EEPROM to use a variety of different serial or parallel interfaces. Bundled with the company’s USB device drivers, this solution enables engineers to add high-speed USB connectivity into new and legacy peripheral designs with a minimum of design and support effort.

In addition, the associated UM232H evaluation module allows engineers to quickly prototype and test the FT232H’s suitability for incorporation into new system designs.

This USB device controller contains USB, serial and parallel protocol engines, eliminating any requirement for USB-specific firmware development. The device supports IO interface levels of 3.3 V with 5 V tolerant inputs, making it suitable for connection to a wide variety of logic, MPUs and FPGAs.

As well as supporting asynchronous serial (UART) interfacing, it also supports interface to many synchronous IOs such as SPI, I²C, JTAG and FPGA programming interfaces, via its inbuilt multiprotocol synchronous serial engine that can communicate at speeds of up to 30 Mbps. In addition, MPSSE can be used by design engineers to implement their own synchronous serial bus protocols.

Incorporated as an interface option into the FT232H is the FT1248 bus - a synchronous, half-duplex serial/parallel interface capable of communicating with external logic at data rates of up to 30 MBps.

The unusual feature of the FT1248 bus is its ability to trade off bandwidth against the number of physical data lines (one, two, four or eight) available to connect the FT232H to external logic to provide optimum flexibility to the system designer.

Integrated 1.8 and 3.3 V low drop-out voltage regulators reduce external component requirements, while the 1 KB transmitter and receiver data buffers coupled with USB2.0 high-speed technology offer greatly improved data throughput and reduced latency response times compared with existing USB2.0-compliant, full-speed products.

Royalty-free drivers for Windows, Linux, MAC and WinCE operating systems are available to download from the FTDI website.
