Data Sheet — MC68HC08AS32
Section 1. General Description
1.1 Introduction
The MC68HC08AS32 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.
1.2 Features
