This makes it an ideal choice for diverse applications, such as home automation systems, point-of-sale terminals and vending machines.

Principle of Operation

The MC68302PV33C is a low-power, 33-MHz microprocessor core based on the 32-bit ColdFire® architecture. The processor is 32-bits wide, with 8KB of on-chip configurable cache for high-performance operation. The processor\'s bus architecture consists of two buses - the ASIC bus and the DRAM bus - connected to the core. The ASIC bus is used for accessing local peripherals, while the DRAM bus is used for accessing external memory. The MC68302PV33C processor core utilizes on-chip configurable cache, which allows faster access and more efficient utilization of RAM resources. The cache is divided between two banks, one containing program and data caches, and the other containing instruction caches. The processor core also employs an on-chip, 32-bit timer, which acts as a single-cycle counter and can be used for timing critical events, scheduling interrupt handling and downloading code from ROM. The core also features an on-chip interrupt controller and DMA controller, to facilitate efficient data stream operations. The processor has also been designed to fit in with the ColdFire® peripheral set, which includes analog-to-digital converters, pulse-width modulation controllers and digital-to-analog converters, for interfacing with various external devices.

Conclusion

The MC68302PV33C processor core is a powerful and low-power microprocessor design, highly suited for embedded applications in the aerospace and defense, industrial automation, and workstation and embedded controller fields. With powerful features like a on-chip configurable cache, an on-chip timer, an interrupt controller, and a DMA controller, as well as an architecture that is fully compatible with the ColdFire® peripheral set, the MC68302PV33C is an excellent choice for demanding embedded applications.
