Product Brief

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

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.
