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 COP8Base 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 1µs instruction cycle, three clock op-
tions (-1 = crystal; -2 = external; -3 = internal RC), one multi-
function 16-bit timer/counter, MICROWIRE/PLUSserial
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, WATCHDOGtimer, 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.
