描述 Description

General Description
The COP424C, COP425C, COP426C, COP444C and COP445C fully static, Single-Chip CMOS Microcontrollers are members of the COPSTM family, fabricated using double-poly, silicon gate microCMOS technology. These Controller Oriented Processors are complete microcomputers containing all system timing, internal logic, ROM, RAM, and I/O necessary to implement dedicated control functions in a variety of applications. Features include single supply operation, a variety of output configuration options, with an in struction set, internal architecture and I/O scheme designed to facilitate keyboard input, display output and BCD data manipulation. The COP424C and COP444C are 28 pin chips. The COP425C and COP445C are 24-pin versions (4 inputs removed) and COP426C is 20-pin version with 15 I/O lines. Standard test procedures and reliable high-density techniques provide the medium to large volume customers with a customized microcontroller at a low end-product cost. These microcontrollers are appropriate choices in many demanding control environments especially those with human interface.
The COP424C is an improved product which replaces the COP420C.
