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 DragonBall
TM . 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.
The MC68328 system integration module (SIM28) consists of several functions that control the system startup, initialization, configuration, and the external bus with a minimum of external devices. The memory interface allows the user to interface gluelessly with the popular SRAM, EPROM as well as PCMCIA 1.0 memory cards, with the assistance of chip-select logic, wait states can be programmable. The hardware and software watchdog timers help the user to do system protections. The interrupt controller accepts and resolves the priority from internal modules and external generated interrupts and also handles the masking and wake-up selection control for power control. The low-power logic can be used to control the CPU power dissipation by altering the frequency or stopping it. The SIM28 is also capable of configuring the pin to allow the user to select either dedicated I/O or parallel I/O. This feature helps to increase the number of available I/O ports by reclaiming when the dedicated function is not in used
