Freescale introduces the MPC8536E PowerQUICC III processor, which the company claims is one of the industry's most energy-efficient gigahertz class embedded SoC devices.

The advanced power and energy management features of the MPC8536E tackle next-generation embedded media processing while enabling designers to address environmental and energy specifications. For instance, printers and other office automation equipment must demonstrate certain environmental benefits and energy usage efficiencies in order to qualify for the ENERGY STAR program. The advanced power management features of the MPC8536E address this challenge by pacing energy usage according to the required workload, thus enabling OEMs to significantly decrease energy usage for their end products.

The MPC8536E processor implements sophisticated features such as Freescale's JOG technology, which lowers power consumption by dynamically changing the CPU frequency. The combination of JOG, together with a fast run mode and rapid recovery from packet-lossless deep sleep creates one of the industry's first embedded energy-to-workload pacing usage models. The device delivers up to 1.5GHz of performance for applications requiring fast processing of rich media content. Target applications for the MPC8536E include advanced multifunction printers (MFPs), home media server and point-of-sale displays, network attached storage (NAS) devices, as well as enterprise networking and storage equipment.

The MPC8536E is built on Freescale's superscalar e500 CPU core, based on Power Architecture technology, and carries forward software compatible with the recently announced QorIQ communications platforms. Freescale's QorIQ P2 platform series is expected to offer a migration path from the MPC8536E to multicore solutions. MPC8536E samples are available now.
