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

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. L.
