Single-Chip 1k and 2k CMOS Microcontrollers
General Description
The
COP424C,
COP445C fully static, Single-Chip CMOS Microcontrollers
are members of the COPS
TM
family, fabricated using dou-
ble-poly, silicon gate microCMOS technology. These Con-
troller Oriented Processors are complete microcomputers
containing all system timing, internal logic, ROM, RAM, and
I/O necessary to implement dedicated control functions in a
variety of applications. Features include single supply oper-
ation, a variety of output configuration options, with an in-
struction set, internal architecture and I/O scheme de-
signed to facilitate keyboard input, display output and BCD
data manipulation. The COP424C and COP444C are 28 pin
chips. The COP425C and COP445C are 24-pin versions (4
inputs removed) and COP426C is 20-pin version with 15 I/O
lines. Standard test procedures and reliable high-density
techniques provide the medium to large volume customers
with a customized microcontroller at a low end-product cost.
These microcontrollers are appropriate choices in many de-
manding control environments especially those with human
interface.

The COP424C is an improved product which replaces the
COP420C.
