General Description  
The COP820CJ is a member of the COP8TM 8-bit Microcon-  
troller family. It is a fully static Microcontroller, fabricated  
using double-metal silicon gate microCMOS technology.  
This low cost Microcontroller is a complete microcomputer  
containing all system timing, interrupt logic, ROM, RAM, and  
I/O necessary to implement dedicated control functions in a  
variety of applications. Features include an 8-bit memory  
mapped architecture, MICROWIRETM serial I/O, a 16-bit  
timer/counter with capture register, a multi-sourced inter-  
rupt, Comparator, WATCHDOGTM Timer, Modulator/Timer,  
Brown out protection and Multi-Input Wakeup. Each I/O pin  
has software selectable options to adapt the device to the  
specific application. The device operates over a voltage  
range of 2.5V to 6.0V. High throughput is achieved with an  
efficient, regular instruction set operating at a 1 ms per in-  
struction rate.
