MC68328 USER’S MANUAL 11/6/97

INTRODUCTION

PRELIMINARY
SECTION 1
INTRODUCTION
The MC68328 DragonBall microprocessor is designed to save you time, power, cost, board
space, pin count, and programming steps when designing your product. This functionality
on a different microprocessor could require 20 separate components, each with 16-64
separate pins. Most of these components require interconnects, which may be duplicates.
In fact, each of these connections could not only have a bad solder joint or misrouted trace,
but may require another part to qualify, purchase, inventory, and maintain. These
components take up valuable space on your PCB and they also consume more power. In
addition, the signals between the CPU and a peripheral could be incompatible and may not
run from the same clock, which could require time delays or other special design constraints.
All this combined makes the DragonBall the microprocessor of choice among many system
designers. Its functionality and glue logic are all optimally connected, timed with the same
clock, fully tested, and uniformly documented. Also, only the essential signals are brought
out to the pins. The DragonBall’s primary package consists of a surface-mount plastic TQFP
designed to leave the smallest possible footprint on your board.
This manual will discuss the details of how to initialize, configure, and operate the
DragonBall microprocessor. However, it assumes you have a basic knowledge of 68K
architecture. If you are not familiar with 68K, you should get copies of the M68000 User’s
Manual, M68000 Programmer’s Reference Manual, and A Discussion of Interrupts for the
MC68000 to use in conjunction with this manual. You can go to the Motorola website at http:/
/www.motorola.com/pso to download these documents or you can contact your local sales
office for printed versions.
