COPCH842C 8-Bit CMOS ROM Based Microcontroller

Note: COP8SA devices are instruction set and pinout compatible supersets of the COP800C Family devices, and are replacements for these in new designs when possible. The COP820C/840C Family ROM based microcontrollers are integrated COP8™ Base core devices with smaller memory (1k/2k), and fewer on-board features. These singlechip CMOS devices are suited for lo.

Features

These singlechip CMOS devices are suited for lower-functionality applications where system cost is of prime consideration.
