COP87LxxCJ/RJ Family

8-Bit CMOS OTP Microcontrollers with 4k or 32k Memory

and Comparator

General Description

The COP87LxxCJ/RJ Family OTP (One Time Program-

mable) microcontrollers are integrated COP8â¢ 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.

Family features include an 8-bit memory mapped architec-

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

tions (-1 = crystal; -2 = external; -3 = internal RC), one multi-

function 16-bit timer/counter, MICROWIRE/PLUSâ¢ serial

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, WATCHDOGâ¢ timer, modulator/timer, Power on

Reset, program code security, 2.7V to 5.5V operation and

20/28 pin packages.

In this datasheet, the term COP87L20CJ refers to the

COP87L20CJ, and COP87L22CJ. COP840CJ refers to the

COP87L40CJ, COP87L42CJ, COP87L40RJ, and

COP87L42RJ.
