Winbond Electronics Corporation W83L517D

The W83L517D is 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 chipset. 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

Version 0.6 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 W83L517D's integration of Flash ROM Interface. 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 W83L517D 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 W83L517D greatly reduces the number of components required for interfacing with floppy disk drives. The W83L517D 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 W83L517D provides one high-speed serial communication ports (UARTs), one of which supports serial Infrared communication.
