Device Overview

MC9S08DZ128 Series devices are members of the low-cost, high-performance HCS08 Family of 8-bit microcontroller units (MCUs). All MCUs in the family use the enhanced HCS08 core and are available with a variety of modules, memory sizes, memory types, and package types.

MC9S08DZ128 Series Features
