COP87LxxCJ/RJ Family

8-Bit CMOS OTP Microcontrollers with 4k or 32k Memory

and Comparator

General Description

The COP87LxxCJ/RJ Family OTP (One Time Program-

mable) microcontrollers are integrated COP8

devices with 4k or 32k memory, and an Analog comparator

(no brownout). These multi-chip CMOS devices are suited

for lower-functionality applications, and as pre-production

devices for a ROM design. Low cost, pin and software com-

patible (plus Brownout) 1k or 2k ROM versions are available

(COP820CJ/840CJ Family). Versions are available for use

with a range of COP8 software and hardware development

tools.

Family features include an 8-bit memory mapped architec-

ture, 10 MHz CKI with 1µs instruction cycle, three clock op-
