Introduction
1.1 Overview
The MC9S08RC/RD/RE/RG are members of the low-cost, high-performance HCS08 Family of 8-bit
microcontroller units (MCUs). All MCUs in this family use the enhanced HCS08 core and are available
with a variety of modules, memory sizes, memory types, and package types.
1.2 Features
Features of the MC9S08RC/RD/RE/RG Family of devices are listed here. Please see Table 1-1 for the
features that are available on the different family members.
