COP882C/COP980C/COP981C/COP982C

Microcontrollers

Schmitt trigger inputs on Port G

General Description

MICROWIRE PLUS serial I/O

Packages:

Ð 20 DIP/SO with 16 I/O pins

Ð 28 DIP/SO with 24 I/O pins

Ð 40 DIP, 36 I/O pins

The COP680C/COP681C/COP682C/COP880C/COP881C

/COP882C/COP980C/COP981C and COP982C are mem-

bers of the COPS^TMmicrocontroller family. They are fully

static parts, fabricated using double-metal silicon gate

microCMOS technology. This low cost microcontroller is a

complete microcomputer containing all system timing, inter-

rupt 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, MI-

CROWIRE/PLUS^TMserial I/O, a 16-bit timer/counter with

capture register and a multi-sourced interrupt. Each I/O pin

has software selectable options to adapt the device to the

specific application. The part operates over a voltage range

of 2.5 to 6.0V. High throughput is achieved with an efficient,

regular instruction set operating at a 1 microsecond per in-

struction rate.

Ð 44 PLCC, 36 I/O pins
