The COP400 or COPS II or simply COPS (Controller Oriented Processor System II) was 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.

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.
