LPC47B37X - 100 PIN ENHANCED SUPER I/O

General Description

The LPC47B37x

is a 3.3V PC99 compliant Super I/O controller.

The LPC47B37x 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.

Key Features

  • 3.3 Volt Operation (5V Tolerant).
  • Floppy Disk Controller (Supports 2 FDCs).
  • Multi-Mode Parallel Port.
  • Two UARTs.
  • 8042 Keyboard Controller.
  • SMBus Controller.
  • Programmable Wakeup Event Interface (nIO_PME Pin).
  • SMI Support (nIO_SMI Pin).
  • GPIOs (39).
  • Fan Speed Control Output.
  • Fan Tachometer Input.
  • ISA IRQ to Serial IRQ Conversion.
  • XNOR Chain.
  • PC99 and ACPI 1.0 Compliant.
