MC68328PV16VA

Product Summary

The MC68328PV16VA 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 MC68328PV16VA 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.
