W83627G-AW Function Overview
GENERAL DESCRIPTION
●The W83627HF and W83627F are evolving product fromWinbond"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 countand still maintains equivalent performance as its ISA interface counterpart. 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 transparentin terms of software which means no BIOS or device driver update is needed except chip-specific configuration.
