Integrated Portable System Processor—DragonBall™

As the portable consumer market grows in full speed, the system requirements are becoming more rigorous than ever. Minimum components, small board space, low power consumption, and low system cost are several minimum criteria to a successful product. To address these needs, Motorola designed a new processor MC68328 DragonBallTM. By providing 3.3V, fully static operation in an efficient package, the MC68328 delivers cost-effective performance to satisfy the extensive requirements of today’s portable consumer market.

KEY FEATURES
