Product Summary

The W83697UF is a LPC I/O. The device features a whole new interface, namely LPC (Low Pin Count) interface, which will be supported in the new generation chip-set. This interface W83697UF as its name suggests is to provide an economical implementation of I/O 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. The W83697UF is fully transparent in terms of software which means no BIOS or device driver update is needed except chip-specific configuration. The W83697UF provides four 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.
