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.

Note 2: Rate of voltage change must be less than 0.5V/ms.
Note 3: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.
Note 4: The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations. Test conditions: All inputs tied to VCC, L and G0 — G5 configured as
outputs and set high. The D port set to zero.
Note 5: Except pin G7: +100 mA, −25 mA (COP920C only). Sampled and not 100% tested. Pins G6 and RESET are designed with a high voltage input network for
factory testing. These pins allow input voltages greater than VCC and the pins will have sink current to VCC when biased at voltages greater than VCC (the pins do
not have source current when biased at a voltage below VCC). The effective resistance to VCC is 750(typical). These two pins will not latch up. The voltage at the
pins must be limited to less than 14V.
