General Description
1.1 Introduction
The MC68HC908GZ16 is a member of the low-cost, high-performance M68HC08 Family of 8-bit
microcontroller units (MCUs). All MCUs in the family use the enhanced M68HC08 central processor unit
(CPU08) and are available with a variety of modules, memory sizes and types, and package types.
The information contained in this document pertains to both the MC68HC908GZ16 and the
MC68HC908GZ8 with the exceptions shown
