MPU PowerQUICC II MPC82xx Processor RISC 32Bit 0.25um 300MHz 3.3V 480Pin TBGA Tray

Overview

The PowerQUICC® II™ integrated communications processor family delivers excellent integration of processing power for networking and communications peripherals, providing customers with an innovative, total system solution for building high-end communications systems. ® Semiconductors"s PowerQUICC II processor family is the next generation of the leading PowerQUICC™ line of integrated communications processors, providing higher performance in all areas of device operation, including greater flexibility, extended capabilities, and higher integration.

Our leading PowerQUICC architecture integrates two processing blocks. One block is a high-performance embedded G2 core and the second block is the Communications Processor Module CPM. The CPM of the MPC8255 processor can support up to two fast serial communications controllers FCCs, one multichannel controller MCC, four serial communications controllers SCCs, two serial management controllers SMCs, one serial peripheral interface SPI and one I2C interface. The combination of the G2 core and the CPM, along with the versatility and performance of the PowerQUICC II processor family, provides customers with enormous potential in developing networking and communications products while significantly reducing time-to-market development stages.
