MC68VZ328 MC68VZ328 dragonball? vz integrated portable system processor product brief the MC68VZ328 (dragonball vz) microprocessor, the third generation of the dragonball ? family of products, is designed to save time, power, and cost in the design and operation of new products. dragonball vz requires less board space and allows for reduced pin count and fewer programming steps in designing your product. the major differences between previous versions of dragonball processors and the new vz product are system-speed improvement and sdram support. all these features combine to make the MC68VZ328 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 MC68VZ328?s primary package consists of tqfp and mbga, designed to occupy the smallest possible footprint on your board. although the dragonball vz is the integrated processor of choice for some of the most popular pda designs, it can be used in a wide variety of applications including exercise monitors, navigation systems, and smart phones. figure 1 on page 2 shows a simplified block diagram of the MC68VZ328.
