The COP410L and COP411L Single-Chip N-Channel Microcontrollers are members of the COPSTM family, fabricated using N-channel, silicon gate MOS 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 instruction set, internal architecture and I/O scheme designed to facilitate keyboard input, display output and BCD data manipulation. The COP411L is identical to the COP410L, but with 16 I/O lines instead of 19. They are an appropriate choice for use in numerous human interface control environments. Standard test procedures and reliable high-density fabrication techniques provide the medium to large volume customers with a customized Controller Oriented Processor at a low end-product cost.
The COP310L and COP311L are exact functional equivalents but extended temperature versions of COP410L and COP411L respectively.
The COP401L should be used for exact emulation.
