PREFACE
The MC68EZ328 (DragonBallEZ) microprocessor, which is the second generation of the
DragonBallª, 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.
These components take up valuable space on your board 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 MC68EZ328 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 MC68EZ328Õs primary package consists of a surface-mount
plastic TQFP designed to leave the smallest possible footprint on your board.
RELATED DOCUMENTATION
This manual will discuss the details of how to initialize, configure, and program the
MC68EZ328 microprocessor. However, it assumes you have a basic knowledge of 68K
architecture. If you are not familiar with 68K, you should get a copy of the following
documents to use in conjunction with this manual.
¥ M68000 UserÕs Manual (part number M68000UM/AD).
¥ M68EZ328ADS UserÕs Manual, which is only available from our website.
¥ M68000 ProgrammerÕs Reference Manual (part number M68000PM/AD).
You can go to the Motorola website at www.mot.com/dragonball and download these
documents or you can contact your local sales office and request a printed version. The
website also has application notes that may be useful to you.
ORGANIZATION OF THIS MANUAL
This manual is organized according to the MC68EZ328 memory map, which is discussed in
Section 1.15 Memory Map.
