General Description
The COP680C COP681C COP682C COP880C COP881C
COP882C COP980C COP981C and COP982C are mem-
bers of the COPSTM 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 PLUSTM 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
