MCS® 51 CHMOS SINGLE-CHIP 8-BIT MICROCONTROLLER

The MCSÉ 51 CHMOS microcontroller products are fabricated on Intel’s reliable CHMOS process and are functionally compatible with the standard MCS 51 HMOS microcontroller products. This technology combines the high speed and density characteristics of HMOS with the low power attributes of CHMOS. This combination expands the effectiveness of the powerful MCS 51 microcontroller architecture and instruction set.
