COP684EK - 8-Bit CMOS ROM Based Microcontrollers with 8k Memory/ Comparator/ and Single-slope A/D Capability

Datasheet Summary

Description

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.

COP87LxxCJ/RJ Family, 8-Bit CMOS OTP Microcontrollers with 4k or 32k Memory and Comparator PRELIMINARY September 1999 COP87LxxCJ/RJ Family 8-Bit CMOS OTP Microcontrollers with 4k or 32k Memory and Comparator General Description 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. Low cost, pin and software compatible (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.
