LPC47B34X Datasheet (Standard Microsystems) - 128 PIN ENHANCED SUPER I/O

LPC47B34X, 128 PIN ENHANCED SUPER I/O

The LPC47B34x * is a 3.3V PC99 compliant Super I/O controller.

The LPC47B34x 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 62 GPIO pins and ISA IRQ to serial IRQ
