mable) 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 com-  
patible (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.  
In this datasheet, the term COP87L20CJ refers to the  
COP87L20CJ, and COP87L22CJ. COP840CJ refers to the  
COP87L40CJ,  
COP87L42RJ.  
COP87L42CJ,  
COP87L40RJ,  
and  
Family features include an 8-bit memory mapped architec-
