微处理器 - MPU FG PQ38 8548 Rev 3 Lead-free
Overview
Our next-generation PowerQUICC® III processors are based on the scalable e500 system-on-chip SoC platform and Power Architecture® processor core. These PowerQUICC III processors, the MPC8548E, MPC8547E, MPC8545E and MP8543E, are designed to deliver gigahertz-plus communications processing performance and advanced features with the exceptional integration and high-speed connectivity required by enterprise networking, telecom transmission and switching, 3G wireless infrastructure, storage and high-end imaging markets.. The processors are designed to offer clock speeds scaling up to 1.5 GHz. They combine the powerful processor core, enhanced peripherals and high-speed interconnect technology to balance processor performance with I/O system throughput.
The next-generation PowerQUICC III processors are based on our 90 nanometer nm silicon-on-insulator SOI copper interconnect process technology, which enables processors to deliver higher performance with lower power dissipation. At 1.5 GHz, these processors deliver a significant performance increase over 130 nm PowerQUICC III devices, adding another level of best-in-class performance and uncompromising integration to the PowerQUICC family.
The MPC8548E, MPC8547E, MPC8545E and MP8543/E processors offer a wide range of high-speed connectivity options, including Gigabit Ethernet GbE, Serial RapidIO® technology and PCI Express®. Support for these high-speed interfaces enables scalable connectivity to network processors and/or ASICs in the data plane while the PowerQUICC III handles complex, computationally demanding control plane processing tasks. These processors also feature next-generation double data rate DDR memory controller, enhanced, GbE support, double precision floating point and integrated security engines that support the Kasumi alogrithm needed for 3G wireless security. In addition, support is provided for exclusive or XOR acceleration needed for parity in storage applications.
