General Description
The COP680C/COP681C/COP682C/COP880C/COP881C
/COP882C/COP980C/COP981C and COP982C are mem-
bers of the COPS
TM
microcontroller 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, inter-
rupt logic, ROM, RAM, and I/O necessary to implement
dedicated control functions in a variety of applications. Fea-
tures include an 8-bit memory mapped architecture, MI-
CROWIRE/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 in-
struction rate.
