GENERAL DESCRIPTION
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 conversion.
