As well as supporting asynchronous serial interfacing, the FT232H also supports interface to many synchronous IOs such as SPI, I2C, JTAG, and FPGA programming interfaces, via its inbuilt Multi-Protocol Synchronous Serial Engine which is capable of communication speeds of up to 30Mbits/s. In addition, MPSSE can be utilised by design engineers to implement their own synchronous serial bus protocols.
Incorporated as an interface option into the FT232H, is the new – a proprietary, synchronous, half-duplex serial/parallel interface capable of communicating with external logic at data rates of up to 30Mbytes/s. The unusual feature of the FT1248 bus is its ability to trade off bandwidth against the number of physical data lines available to connect the FT232H to external logic, thus providing optimum flexibility to the system designer.
Integrated 1.8V and 3.3V low drop-out voltage regulators reduce external component requirements, whilst the generous 1 Kbyte transmitter and receiver data buffers coupled with USB2.0 Hi-Speed technology offer greatly improved data throughput and reduced latency response times compared to 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.
Package options for the FT232H are 48 pin LQFP or 48 pin QFN Pb-free packages. Both FT232H variants have an operational temperature range of -40°C to +85°C. FT232HL devices are priced at US$2.75 whilst FT232HQ devices are priced at US$2.60. The customer evaluation module enables rapid prototyping / testing of the FT232H platform and connects to a standard 0.6” wide, 28 pin DIP socket. UM232H modules are priced at US$20 each.
