General Description
The LPC47M10x* is a 3.3V (5V tolerant) PC98/PC99 compliant Super I/O controller. The LPC47M10x implements the LPC interface, a pin reduced ISA bus interface which provides the same or better performance as the ISA/X-bus with a substantial savings in pins used. The LPC47M10x provides fan control through two fan speed control output pins and two fan tachometer input pins. It also provides 37 general purpose input/output (GPIO) pins, a dual game port interface and MPU-401 MIDI support.
