COP820C/840C Family
8-Bit CMOS ROM Based Microcontrollers with 1k or 2k
Memory
General Description
Note: COP8SA devices are instruction set and pinout com-
patible supersets of the COP800C Family devices, and are
replacements for these in new designs when possible.
The COP820C/840C Family ROM based microcontrollers
are integrated COP8Base core devices with smaller
memory (1k/2k), and fewer on-board features. These single-
chip CMOS devices are suited for lower-functionality appli-
cations where system cost is of prime consideration. Pin and
software compatible (different VCC range) 4k/32k OTP ver-
sions are available (COP87LxxCJ/RJ Family). Erasable win-
dowed 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 Hz CKI with 1µs instruction cycle, one multi-function
16-bit timer/counter with PWM, MICROWIRE/PLUSserial
I/O, power saving HALT mode, three clock modes, high cur-
rent outputs, software selectable I/O options, 2.3v-6.0v op-
eration and 20/28 pin packages.
