Single Channel Hi-Speed USB to UART/FIFO Interface IC

Future Technology Devices International Ltd'sFT232H USB2.0 Hi-Speed device is a versatile single channel USB to UART/FIFOinterface device that can be configured via EEPROM to use a variety ofdifferent serial or parallel interfaces. Bundled with FTDI's USB devicedrivers, this solution enables engineers to add Hi-Speed USB connectivity intonew and legacy peripheral designs with a minimum of design and support effort.The associated UM232H evaluation module allows engineers to prototype and teststhe FT232H's suitability for incorporation into new system designs. This USB devicecontroller contains USB, serial and parallel protocol engines, eliminating anyrequirement for USB specific firmware development. The device supports IOinterface levels of 3.3V with 5V tolerant inputs, making it suitable forconnection to a wide variety of logic, MPUs and FPGAs.

As well assupporting asynchronous serial (UART) interfacing, the FT232H also supportsinterface to many synchronous IOs such as SPI, I2C, JTAG, and FPGA programminginterfaces, via its inbuilt Multi-Protocol Synchronous Serial Engine (MPSSE),which is capable of communication speeds of up to 30Mbits/s. MPSSE can beutilized by design engineers to implement their own synchronous serial busprotocols.

Incorporated as aninterface option into the FT232H, is the new FT1248 bus - a proprietary,synchronous, half-duplex serial/parallel interface capable of communicatingwith external logic at data rates of up to 30Mbytes/s. The FT1248 has theability to trade off bandwidth against the number of physical data lines (one,two, four or eight) available to connect the FT232H to external logic forflexibility to the system designer.

Integrated 1.8 and3.3V low drop-out (LDO) voltage regulators reduce external componentrequirements, while the 1 Kbyte transmitter and receiver data buffers coupledwith USB2.0 Hi-Speed technology have data throughput and reduced latencyresponse times compared to existing USB2.0 compliant full speed products.Royalty free drivers for Windows, Linux, MAC and WinCE operating systems areavailable to download from the FTDI website.

Package options forthe FT232H are 48 pin LQFP (FT232HL) or 48 pin QFN (FT232HQ) Pb-free packages.Both FT232H variants have an operational temperature range of -40 to +85C. FT232HL devices are priced atUS$2.75 (for 1,000 pcs) while FT232HQ devices are priced at US$2.60 (for 1000pcs). The UM232H customer evaluation module enables rapid prototyping / testingof the FT232H platform and connects to a standard 0.6 inches wide, 28 pin DIPsocket. UM232H modules are priced at US$20 each (for 1 to 9 pcs).
