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/PLUS
TM
serial 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 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 V
CC
, L, C and G ports TRI-STATE
and tied to ground, all outputs low and tied to ground.
Note 5: Pins G6 and RESET are designed with a high voltage input network for factory testing. These pins allow input voltages greater than V
CC
and the pins will
have sink current to V
CC
when biased at voltages greater than V
CC
(the pins do not have source current when biased at a voltage below V
CC
). The effective
resistance to V
CC
is 750
(typ). These two pins will not latch up. The voltage at the pins must be limited to less than 14V.
Note 6: To maintain RAM integrity, the voltage must not be dropped or raised instantaneously.
