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 V_CCrange) 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.
