COP912C  
8-Bit Microcontroller  
Family features include an 8-bit memory mapped architec-  
ture, 10MHz CKI with 2.5us(912C) or 2us(912CH) instruction  
cycle, one multi-function 16-bit timer/counter with PWM,  
MICROWIRE/PLUS(tm) serial I/O, power saving HALT  
mode, three clock modes, high current outputs, software se-  
lectable I/O options, multi-volt operation and 20 pin pack-  
ages.  
General Description  
Note: COP8SA devices are instruction set and pinout com-  
patible supersets of the COP912C devices, and are replace-  
ments for these in new designs when possible.  
The COP912C ROM based microcontrollers are integrated  
COP8(tm) Base core devices with smaller memory (768  
bytes), and fewer on-board features. These single-chip  
CMOS devices are suited for lower-functionality applications  
where system cost is of prime consideration. Pin and soft-  
ware compatible (different Vcc range) 4k/32k OTP versions  
are available (COP87LxxCJ/RJ Family). Erasable windowed  
versions are available for use with a range of COP8(tm) soft-  
ware and hardware development tools.
