DESCRIPTION

The ETL9444/L9445 and ETL9344/L9345 Single-

Chip N-Channel Microcontrollers are fully compati-

ble with the COPS

® family, fabricated using

N-channel, silicon gate XMOS technology. They are

complete microcomputers containing all system ti-

ming, internal logic, ROM, RAM and I/O necessary

to implement dedicated control functions in a variety

of applications. Features include single supply ope-

ration, a variety of output configuration options, with

an instruction set, internal architecture and I/O

scheme designed to facilitate keyboard input, dis-

play output and BCD data manipulation. The

ETL9445 is identical to the ETL9444, except with 19

I/O lines instead of 23 : They are an appropriate

choice for use in numerous human interface control

environments. Standard test procedures and relia-

ble high-density fabrication techniques provide the

medium to large volume customers with a customi-

PIN CONNECTION
