Intel Corporation 83C51KB
The 83C51KB is a highly integrated keyboard microcontroller for the standard and advanced desktop keyboard industry. The integration of external components into the microcontroller reduces overall keyboard control system manufacturing cost in terms of the number of components used, the amount of PCB space required, reduced inventory, and a reduction in required assembly activities. The 83C51KB product line is manufactured with Intel state of the art complimentary high-performance metallic oxide semiconductor (CHMOS) design rules.DESCRIPTION
