COP224C/COP225C/COP226C/COP244C/COP245C  
Single-Chip 1k and 2k CMOS Microcontrollers  
General Description  
Features  
Y
Lowest power dissipation (600 mW typical)  
The COP224C, COP225C, COP226C, COP244C and  
COP245C 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 COP224C and COP244C are 28 pin  
chips. The COP225C and COP245C are 24-pin versions (4  
inputs removed) and COP226C 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.
