COP888EK

8-Bit CMOS ROM Based Microcontrollers with 8k

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

General Description

The COP888EK ROM based microcontrollers are highly in-

tegrated COP8™ Feature core devices with 8k memory and

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

CC range)

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

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

hardware development tools.

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/

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

multiplexor, an analog current source and V

CC reference,

two power saving HALT/IDLE modes, idle timer, MIWU, high

current outputs, software selectable I/O options, WATCH-

DOG™ timer and Clock Monitor, Low EMI 2.5V to 6.0V op-

eration and 28/40/44 pin packages.
