COP224C/COP225C/COP226C/COP244C/COP245C

Single-Chip 1k and 2k CMOS Microcontrollers

General Description

Features

Lowest power dissipation (600 mW typical)

The COP224C, COP225C, COP226C, COP244C and

COP245C fully static, Single-Chip CMOS Microcontrollers

are members of the COPS^TMfamily, 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 COP224C and COP244C are 28 pin

chips. The COP225C and COP245C are 24-pin versions (4

inputs removed) and COP226C 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.

Fully static (can turn off the clock)

Power saving IDLE state and HALT mode

4.4 ms instruction time

2k x 8 ROM, 128 x 4 RAM (COP244C/COP245C)

1k x 8 ROM, 64 x 4 RAM (COP224C/COP225C/

COP226C)

23 I/O lines (COP244C and COP224C)

True vectored interrupt, plus restart

Three-level subroutine stack

Single supply operation (4.5V to 5.5V)

Programmable read/write 8-bit timer/event counter

Internal binary counter register with MICROWIRE^TM

serial I/O capability

General purpose and TRI-STATE outputs

LSTTL/CMOS output compatible

Software/hardware compatible with COP400 family

Military temperature ( 55 C to 125 C) operation
