Section 1. General Description

1.1 Introduction

The MC68HC08AS32A — 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.
