COP888EK

8-Bit CMOS ROM Based Microcontrollers with 8k

Memory, Comparator, and Single-slope A/D Capability

Family features include an 8-bit memory mapped architec-

ture, 10 MHz CKI with 1µs instruction cycle, three multi-

function 16-bit timer/counters with PWM, MICROWIRE/

General Description

The COP888EK ROM based microcontrollers are highly in-

™

tegrated COP8 Feature core devices with 8k memory and

™

PLUS serial I/O, one analog comparator with seven input

advanced features including a Multi-Input Comparator and

Single-slope A/D capability. These single-chip CMOS de-

vices are suited for applications requiring a full featured, low

EMI controller with an analog comparator, current source,

and voltage reference. The COP87L88EK/RK Family de-

vices are pin and software compatible (different V_CCrange)

16k or 32k OTP (One Time Programmable) versions for pre-

production, and for use with a range of COP8 software and

hardware development tools.
