COP912C COP912CH 8-Bit Microcontroller
General Description
The COP912C COP912CH are members of the COP8TM
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
MICROWlRETM 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

OSCILLATOR CIRCUITS
The device can be driven by a clock input which can be
between DC and 5 MHz
CRYSTAL OSCILLATOR
By selecting CKO as a clock output CKI and CKO can be
connected to create a crystal controlled oscillator Table I
shows the component values required for various standard
crystal values
R C OSCILLATOR
By selecting CKI as a single pin oscillator CKI can make an
R C oscillator CKO is available as a general purpose input
and or HALT control Table II shows variation in the oscilla-
tor frequencies as functions of the component (R and C)

HALT MODE
The device is a fully static device The device enters the
HALT mode by writing a one to the G7 bit of the G data
register Once in the HALT mode the internal circuitry does
not receive any clock signal and is therefore frozen in the
exact state it was in when halted In this mode the chip will
only draw leakage current
The device supports two different ways of exiting the HALT
mode The first method is with a low to high transition on the
CKO (G7) pin This method precludes the use of the crystal
clock configuration (since CKO is a dedicated output) and
so may be used either with an RC clock configuration (or an
external clock configuration) The second method of exiting
the HALT mode is to pull the RESET low
Note To allow clock resynchronization it is necessary to program two
NOP’s immediately after the device comes out of the HALT mode
The user must program two NOP’s following the ‘‘enter HALT mode’’
(set G7 data bit) instruction
