Winbond Electronics Corporation W83627EHF

W83627EHF is an 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 new generation 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. 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 W83627EHF 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 W83627EHF greatly reduces the number of components required for interfacing with floppy disk drives. W83627EHF 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. W83627EHF provides two high-speed serial communication ports (UARTs), one of which supports serial Infrared communication. Each UART includes a 16-byte send/receive FIFO, a programmable baud rate generator, complete modem control capability, and a processor interrupt system.
