... Enhanced Super I/O with LPC Interface for Server Applications General Description The LPC47S422 is a 3.3V PC99 compliant Super I/O controller. The LPC47S422 implements the LPC interface, a pin reduced ISA interface which provides the same or better performance as the ISA/X- bus with a substantial savings in pins used. The part provides 39 GPIO pins, an SMBus controller, a fan speed control output, a fan tachometer input, four ISA IRQs that can be routed to any of the serial IRQs, and an X-Bus interface ...
