The Controller Oriented Processor System I or COPS I (originally just COPS) is a family of 4-bit microcontrollers developed by National Semiconductor. COPS, as it was originally called, was released to the market in 1976. It was manufactured in PMOS technology. A year later, National introduced the COPS II, an NMOS (and later CMOS) versions of those chips.

The MM5781+MM5782 solution allowed for more complex designs whereas the MM5799 served as a single-chip solution. The MM57140 was an even more advanced chip incorporating the keyboard input and display driver.
