Description
The LPC47M534-NC is a 3.3V (5V tolerant) PC98/PC99 compliant Super I/O controller. It implements the LPC interface, a pin reduced ISA bus interface that provides the same or better performance as the ISA/X-bus with a substantial savings in pins used. This component provides fan control through two fan speed control output pins and two fan tachometer input pins. It also offers 37 general-purpose input/output (GPIO) pins, a dual game port interface, and MPU-401 MIDI support.
