GENERAL DESCRIPTION\nThe W83627HF and W83627F are evolving product fromWinbond's most popular I/O family. They\nfeature 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.FEATURES\nGeneral\n?
