General Description  
Features  
Y
Lowest power dissipation (50 mW typical)  
The COP424C, COP425C, COP426C, COP444C and  
COP445C fully static, Single-Chip CMOS Microcontrollers  
are members of the COPSTM family, fabricated using dou-  
ble-poly, silicon gate microCMOS technology. These Con-  
troller Oriented Processors are complete microcomputers  
containing all system timing, internal logic, ROM, RAM, and  
I/O necessary to implement dedicated control functions in a  
variety of applications. Features include single supply oper-  
ation, a variety of output configuration options, with an in-  
struction set, internal architecture and I/O scheme de-  
signed to facilitate keyboard input, display output and BCD  
data manipulation. The COP424C and COP444C are 28 pin  
chips. The COP425C and COP445C are 24-pin versions (4  
inputs removed) and COP426C is 20-pin version with 15 I/O  
lines. Standard test procedures and reliable high-density  
techniques provide the medium to large volume customers  
with a customized microcontroller at a low end-product cost.  
These microcontrollers are appropriate choices in many de-  
manding control environments especially those with human  
interface.
