1. Introduction
This document describes EMAC’s iPac HCS12 Single Board Computer (SBC) module. The iPac HCS12 is a PC/104 SBC
sized module that provides a wide variety of I/O. Controlled by Motorola’s powerful HCS12 processor this module provides
maximum flexibility with ample processing speed for most control applications. Although being extremely powerful with
ample I/O for demanding applications, this board consumes minimal power, is low cost, and has a small footprint. The iPac
HCS12 uses the Standard PC/104 form factor (3.8" x 3.5") allowing the use of standard PC/104 mounting hardware and
enclosures. The features of the iPac HCS12 are as follows:
