COP87L42RJ Datasheet (National Semiconductor) - 8-Bit CMOS OTP Microcontrollers with 4k or 32k Memory and Comparator

COP87L42RJ, 8-Bit CMOS OTP Microcontrollers with 4k or 32k Memory and Comparator

The COP87LxxCJ/RJ Family OTP (One Time Programmable) microcontrollers are integrated COP8™ Base core 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.
