Product Brief

Integrated Portable System Processor—DragonBall ΤΜ

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.

The MC68328 (shown in Figure 1) is the first integrated processor of the 68K Family to include a LCD controller, which demonstrates Motorola’s focus on the portable market. With addition to the LCD controller, MC68328 provides key features that are suitable for many portable applications. Modules like RTC, PWM, Timers, Master SPI, Slave SPI, UART, and the System Integration Module (SIM28) facilitate the system engineer with more flexibility and resources to design efficient and innovative products.
