COP820CJ/COP840CJ Family

8-Bit CMOS ROM Based Microcontrollers with 1k or 2k

Memory, Comparator and Brown Out Detector

General Description

The COP820CJ/840CJ Family ROM based microcontrollers

are integrated COP8â¢ Base core devices with 1k or 2k

memory, an Analog comparator and Brownout detection.

These single-chip CMOS devices are suited for lower-

functionality applications where power and voltage fluctua-

tions are a consideration. Pin and software compatible (no

Brownout; different Vcc range) 4k/32k OTP versions are

available (COP87LxxCJ/RJ Family) for pre-production, and

for use with a range of COP8 software and hardware devel-

opment tools.

Family features include an 8-bit memory mapped architec-

ture, 10MHz CKI with 1us instruction cycle, one multi-

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

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

MIWU, on-chip R/C oscillator capacitor (COP840CJ), high

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

DOGâ¢ timer, modulator/timer, Brownout detector, Power on

Reset, 2.5v-6.0v operation, and 16/20/28 pin packages.

In this datasheet, the term COP820CJ refers to packages in-

cluding the COP820CJ, COP822CJ, and COP823CJ; and

COP840CJ refers to COP840CJ, COP842CJ, COP940CJ,

and COP942CJ.
