COP888CF  
8-Bit CMOS ROM Based Microcontrollers with 4k  
Memory and A/D Converter  
Family features include an 8-bit memory mapped architec-  
ture, 10 MHz CKI with 1 µs instruction cycle, two multi-  
General Description  
The COP888CF ROM based microcontrollers are highly in-  
™
function 16-bit timer/counters, MICROWIRE/PLUS serial  
™
tegrated COP8 Feature core devices with 4k memory and  
I/O, one 8-bit/8-channel A/D converter with prescaler and  
both differential and single ended modes, crystal or R/C os-  
cillator, two power saving HALT/IDLE modes, idle timer,  
MIWU, high current outputs, software selectable I/O options,  
advanced features including an A/D Converter. These single-  
chip CMOS devices are suited for applications requiring a  
full featured controller with an 8-bit A/D converter. Pin and  
software compatible (different VCC range) 16k/32k OTP  
(One Time Programmable) versions are available  
(COP87L88CF Family) for pre-production, and for use with a  
range of COP8 software and hardware development tools.  
™
WATCHDOG timer and Clock Monitor, 2.5V to 6.0V opera-  
tion and 28/40/44 pin packages.
