COP880C
Microcontrollers
General Description
The following part numbers are pin count and tempera-
ture variations of the COP880C: COP680C/COP681C/
COP682C/COP881C
/COP882C/COP980C/
COP981C/COP982C.
The COP880C devices are members of the COP8 microcon-
troller family. They are fully static parts, fabricated using
double-metal silicon gate microCMOS technology. This low
cost microcontroller is a complete microcomputer containing
all system timing, interrupt logic, ROM, RAM, and I/O nec-
essary to implement dedicated control functions in a variety
of applications. Features include an 8-bit memory mapped
architecture, MICROWIRE/PLUSserial I/O, a 16-bit timer/
counter with capture register and a multi-sourced interrupt.
Each I/O pin has software selectable options to adapt the
device to the specific application. The part operates over a
voltage range of 2.5 to 6.0V. High throughput is achieved
with an efficient, regular instruction set operating at a 1
microsecond per instruction rate.

Note 9: Rate of voltage change must be less than 0.5V/ms.
Note 10: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.
Note 11: The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations. Test conditions: All inputs tied to VCC, L, C and G ports TRI-STATE
and tied to ground, all outputs low and tied to ground.
Note 12: 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(typ). These two pins will not latch up. The voltage at the pins must be limited to less than 14V.
Note 13: To maintain RAM integrity, the voltage must not be dropped or raised instantaneously.
