COP820CJ/COP840CJ Family  
8-Bit CMOS ROM Based Microcontrollers with 1k or 2k  
Memory, Comparator and Brown Out Detector  
Family features include an 8-bit memory mapped architec-  
ture, 10MHz CKI with 1us instruction cycle, one multi-  
General Description  
The COP820CJ/840CJ Family ROM based microcontrollers  
™
function 16-bit timer/counter, MICROWIRE/PLUS serial  
™
are integrated COP8 Base core devices with 1k or 2k  
I/O, one analog comparator, power saving HALT mode,  
MIWU, on-chip R/C oscillator capacitor (COP840CJ), high  
current outputs, software selectable I/O options, WATCH-  
memory, an Analog comparator and Brownout detection.  
These single-chip CMOS devices are suited for lower-  
functionality applications where power and voltage fluctua-  
tions 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 devel-  
opment tools.  
™
DOG timer, modulator/timer, Brownout detector, Power on  
Reset, 2.5v-6.0v operation, and 16/20/28 pin packages.  
In this datasheet, the term COP820CJ refers to packages in-  
cluding the COP820CJ, COP822CJ, and COP823CJ; and  
COP840CJ refers to COP840CJ, COP842CJ, COP940CJ,  
and COP942CJ.
