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 COP8
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/PLUS
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-
DOG
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.
