描述 Description

The CA3228 is a monolithic integrated circuit designed as an automotive speed-control system.

The system monitors vehicle speed and compares it to a stored reference speed. Any deviation in vehicle speed causes a servo mechanism to open or close the engine throttle as required to eliminate the speed error. The reference speed, set by the driver, is stored in a 9-bit counter.
