Gigahertz-class processor stresses energy efficiency for applications with varying usage scenarios

MPC8536E PowerQUICC (quad-integrated-communications-controller) III processors include advanced power- and energy-management features to support embedded media applications, such as printers and office-automation equipment to meet environmental and governmental energy-regulatory requirements, such as Energy Star. The e500 Power processor family features the company’s JOG (joint-operations-graphic) technology to maintain network work traffic even when the processor is in a deep-sleep state. This energy-pacing model enables designers to match several power states to match the workload. The devices support processing at speeds as high as 1.5 GHz for the heaviest-workload time. During light-workload periods, the device supports dynamic changes in the core frequency. The device’s deep-sleep mode splits the power plane to turn off supply voltage to high-power, fast transistors in the core and cache and enable packet-lossless deep sleep by supporting advanced Ethernet-packet filtering.
The MPC8536E includes a 512-kbyte L2 cache, an integrated security engine, 64-bit DDR2 or DDR3 scaling to a 667-MHz data rate, 32-bit PCI (peripheral-component interconnect), multiple PCIe (PCI Express), enhanced local-bus-I/O interfaces, and two GbE (gigabit-Ethernet) interfaces. It also provides support for PCI, I2C (inter-integrated-circuit), DUARTs (dual universal asynchronous-receiver/transmitters) and local-bus connections.
MPC8536E samples are available now, and production will begin in August 2009. The devices are software-compatible with the company’s QorIQ product line. The MPC8536DS development system and the MPC8536RDK low-cost reference system in the COM Express form factor are available
