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-
