COP912C COP912CH 8-Bit Microcontroller
General Description
The COP912C COP912CH are members of the COP8^TM
8-bit MicroController family They are fully static Microcon-
trollers fabricated using double-metal silicon gate micro-
CMOS technology These low cost MicroControllers are
complete microcomputers containing all system timing in-
terrupt 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
MICROWlRE^TM serial I O a 16-bit timer counter with cap-
ture register and a multi-sourced interrupt Each I O pin has
software selectable options to adapt the device to the spe-
cific application The device operates over voltage ranges
from 2 3V to 4 0V (COP912C) and from 4 0V to 5 5V
(COP912CH) High throughput is achieved with an efficient
regular instruction set operating at a minimum of 2 ms per
instruction rate
