General Description
1.1 Introduction
The MC68HC908AT32 is a member of the low-cost, high-performance M68HC08 Family of 8-bit
microcontroller units (MCUs). The M68HC08 Family is based on the customer-specified integrated circuit
(CSIC) design strategy. 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.
This part is designed to emulate two separate automotive parts: the MC68HC08AZ32 and the
MC68HC08AS20. This document demonstrates the unique qualities of both parts. In the case of
similarities, these are explained in the beginning sections of the specification.
1.2 Features
Refer to Table 1-1 for an encapsulated feature list comparison between the MC68HC08AZ32 and
MC68HC08AS20.
