Winbond Electronics Corporation W83627HF

The W83627HF and W83627F are evolving product from Winbond's most popular I/O family. They feature a whole new interface, namely LPC（Low Pin Count）interface, which will be supported in the next generation Intel chip-set. This interface as its name suggests is to provide an economical implementation of I/O's interface with lower pin count and still maintains equivalent performance as its ISA interface counterpart.

GENERAL DESCRIPTION

Approximately 40 pin counts are saved in LPC I/O comparing to ISA implementation. With this additional freedom, we can implement more devices on a single chip as demonstrated in W83627F/HF's integration of Game Port and MIDI Port.It is fully transparent in terms of software which means no BIOS or device driver update is needed except chip-specific configuration. The disk drive adapter functions of W83627F/HF include a floppy disk drive controller compatible with the industry standard 82077/ 765, data separator, write pre-compensation circuit, decode logic, data rate selection, clock generator, drive interface control logic, and interrupt and DMA logic. The wide range of functions integrated onto the W83627F/HF greatly reduces the number of components required for interfacing with floppy disk drives. The W83627F/HF supports four 360K, 720K, 1.2M, 1.44M, or 2.88M disk drives and data transfer rates of 250 Kb/s, 300 Kb/s, 500 Kb/s,1 Mb/s, and 2 Mb/s. The W83627F/HF provides two high-speed serial communication ports（UARTs）, one of which supports serial Infrared communication.
