function 16-bit timer/counter, MICROWIRE/PLUS serial

The COP87LxxCJ/RJ Family OTP (One Time Program-

I/O, one analog comparator, power saving HALT mode with

multi-sourced wakeup/interrupt capability, on-chip R/C oscil-

lator capacitor, high current outputs, software selectable I/O

options, WATCHDOG timer, modulator/timer, Power on

mable) microcontrollers are integrated COP8 Base core

devices with 4k or 32k memory, and an Analog comparator

(no brownout). These multi-chip CMOS devices are suited

for lower-functionality applications, and as pre-production

devices for a ROM design. Low cost, pin and software com-

patible (plus Brownout) 1k or 2k ROM versions are available

(COP820CJ/840CJ Family). Versions are available for use

with a range of COP8 software and hardware development

tools.

In this datasheet, the term COP87L20CJ refers to the

COP87L20CJ, and COP87L22CJ. COP840CJ refers to the

COP87L40CJ,

COP87L42RJ.

COP87L42CJ,

COP87L40RJ,

and

Family features include an 8-bit memory mapped architec-

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