The MPC8544/E PowerQUICC™ III is designed to offer the unique combination of high performance, exceptional integration and lower overall power consumption required for networking, communications and industrial control applications.

The MPC8544/E is designed to include a high-performance e500 processor core built on Power Architecture™ technology, enhanced peripherals and high-speed interconnect technology to balance processor performance with I/O system throughput enabling clock speeds scaling from 667MHz up to 1.067 GHz. Third-generation PowerQUICC III processors are based on Freescale’s 90 nanometer (nm) silicon-on-insulator (SOI) copper interconnect process technology, which is designed to enable the processors to deliver higher performance with lower power dissipation.

The MPC8544/E processor is designed to offer a wide range of high-speed connectivity options, including Gigabit Ethernet (GigE) interfaces with SGMII support and multiple PCI Express® connections. Support for these high-speed interfaces should enable scalable connectivity to network processors and/or ASICs in the data plane while the PowerQUICC III is designed to handle complex, computationally demanding control plane processing tasks. The MPC8544/E is also designed to provide support for legacy PowerQUICC III interfaces such as PCI, I2C, dual universal asynchronous receiver/transmitters (DUART) and local bus connections. These processors are also designed to feature a next-generation double data rate (DDR2) memory controller, enhanced GigE support, v2 e500 double precision floating point and the field proven 90nm PowerQUICC III integrated security engines.
