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⢠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.
