SINGLE CHIP 8-BIT MICROCOMPUTER
WITH ON-CHIP AID CONVERTER
DESCR IPTION
The NEC I1PD8022 is designed for low cost, high volume applications requiring large
ROM space, analog to digital conversion capability, a capacitive touchpanel keyboard
interface and/or a power line time base. The I1PD8022 satisfies these requirements by
integrating on onechip,an 8·bit I1PD8021 type processor with 2K of ROM, a 2 channel
8-bit A/D converter, a high impedance comparator input port, and a zero crossing
detector.
