Freescale Semiconductor's MPC5121e mobileGT processor is a "motherboard-on-a-chip" device designed to provide the embedded processing performance and on-chip peripherals and connectivity for ultramobile PC (UMPC) platforms. Operating within a 2W power envelope, the processor's highly integrated triple-core architecture virtually eliminates the need for bulky heat sinks and noisy fans required by traditional power-hungry personal computing architectures.

Built on Power Architecture technology, MPC5121e is the latest member of Freescale's mobileGT processor family. Manufactured on Freescale's 90nm low-power CMOS technology, the MPC5121e device is designed to deliver exceptional multimedia performance and feature-rich user interfaces within a low power envelope, without sacrificing flexibility and robustness.

MPC5121e is built around an efficient triple-core architecture consisting of a Power Architecture core, a 3D-graphics processor core and a CD-quality audio processor core. The powerful 3D-graphics processor is engineered to provide a graphics pipeline capable of gaming-class 3D rendering while keeping the DRAM bandwidth requirements to a bare minimum. The triple-core MPC5121e architecture is designed to allow the costly distributed DRAM memory systems within a PC to be merged into a single shared DRAM memory system.

The MPC5121e device's 32bit Truecolor display controller provides the multiplane blending capabilities to drive a wide range of display resolutions including 720p (1,280x720) and WXGA (1,366x768). The on-chip audio core provides a flexible, efficient audio DSP/RISC architecture engineered to offload the CPU from audio ripping, playback and sound enhancement processing such as MP3, WMA and Ogg Vorbis.

The processor's rich set of peripheral interfaces is engineered to reduce overall system cost. In addition to the traditional peripheral interfaces, SDIO and serial interfaces provide the opportunity to leverage a host of low-cost wireless chipsets. Based on its high level of integration and exceptional price/performance, the mobileGT platform is designed to help drive down the cost of full-featured, Web 2.0-enabled personal computing to the Rs.11,843.52 ($300) threshold and below.

The MPC5121e processor powers LimePC's full line of compact computing products, including UMPCs, pad-style PCs with large touchpad LCD screens, notebook and desktop PCs, and mini-ITX developer kits. LimePC's consumer PC products will feature one or more MPC5121e processors and a LimeOS and LimeSuite applications software bundle. Initially available in China, LimePC products will be available in the United States by the 2008 holiday season.
