COP912C/COP912CH 8-Bit Microcontroller  
General Description  
CPU/Instruction Set Features  
Y
The COP912C/COP912CH are members of the COP8TM  
8-bit MicroController family. They are fully static Microcon-  
trollers, fabricated using double-metal silicon gate micro-  
CMOS technology. These low cost MicroControllers are  
complete microcomputers containing all system timing, in-  
terrupt logic, ROM, RAM, and I/O necessary to implement  
dedicated control functions in a variety of applications. Fea-  
tures include an 8-bit memory mapped architecture,  
MICROWlRETM serial I/O, a 16-bit timer/counter with cap-  
ture register and a multi-sourced interrupt. Each I/O pin has  
software selectable options to adapt the device to the spe-  
cific application. The device operates over voltage ranges  
from 2.3V to 4.0V (COP912C) and from 4.0V to 5.5V  
(COP912CH). High throughput is achieved with an efficient,  
regular instruction set operating at a minimum of 2 ms per  
instruction rate.  
Instruction cycle time of 2 ms for COP912CH and  
2.5 ms for COP912C
