COP410C/COP411C/COP310C/COP311C
Single-Chip CMOS Microcontrollers
General Description
Features
Y
Lowest power dissipation (40 mW typical)
The COP410C, COP411C, COP310C, and COP311C fully
static, single-chip CMOS microcontrollers are members of
the COPSTM family, fabricated using double-poly, silicon-
gate CMOS technology. These controller-oriented proces-
sors are complete microcomputers containing all system
timing, internal logic, ROM, RAM, and I/O necessary to im-
plement dedicated control functions in a variety of applica-
tions. Features include single supply operation, a variety of
output configuration options, with an instruction set, internal
architecture, and I/O scheme designed to facilitate key-
board input, display output, and BCD data manipulation. The
COP411C is identical to the COP410C but with 16 I/O lines
instead of 20. They are an appropriate choice for use in
numerous human interface control environments. Standard
test procedures and reliable high-density fabrication tech-
niques provide the medium to large volume customers with
a customized controller-oriented processor at a low end-
product cost.
