The COP820CJ/840CJ Family ROM based microcontrollers are integrated COP8TM Base core devices with 1k or 2k memory, an Analog comparator and Brownout detection. These single-chip CMOS devices are suited for lowerfunctionality applications where power and voltage fluctuations are a consideration. Pin and software compatible (no Brownout; different Vcc range) 4k/32k OTP versions are available (COP87LxxCJ/RJ Family) for pre-production, and for use with a range of COP8 software and hardware development tools.
