National Semiconductor COP820CJ/COP840CJ Family Datasheet
The COP820CJ/COP840CJ Family consists of 8-bit CMOS ROM-based microcontrollers integrated with a COP8 base core, 1k or 2k memory, an analog comparator, and a Brownout detector. These single-chip devices are designed for lower-functionality applications where power consumption and voltage fluctuations are significant considerations. The family includes devices with 1k or 2k ROM and 64 or 128 bytes of RAM, available in 16, 20, and 28-pin DIP and SOIC packages.
