The Controller Oriented Processor System II or COPS400 or COPS II or simply COPS is a family of 4-bit microcontrollers developed by National Semiconductor. The family was introduced a year after the COPS I in 1977. Components in the COPS II were made in NMOS and CMOS technology instead of PMOS as used in COPS I. The COPS II obsoleted the COPS I family soon after release. As their name implies, these chips found their way to many consumer controllers and electric appliances.
2nd sources
National Semiconductor, while almost exclusively never 2nd sourcing their own designs, did license the COPS II to Western Digital in 1980. WD continued manufacturing the COPS II until 1984 when they moved into the data storage market.
