W83697SF数据手册Winbond中文资料规格书

描述 Description

GENERAL DESCRIPTION
The W83697SF 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 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. Approximately 40 pin counts are saved in LPC I/O comparing to ISA implementation.FEATURES
