| Integrated Communication Processors MPC8308 PowerQUICC(R) II Pro Processor Overview The MPC8308 is a cost-effective, lowpower, highly integrated PowerQUICC(R) II Pro processor designed to address the requirements of networking applications such as smart grid home energy gateways, data concentrators, wireless LAN access points, wireless femto base stations and industrial applications such as industrial control and factory automation. It extends the PowerQUICC II Pro family by balancing the higher MIPS/MHz performance provided by the e300 core with low power consumption at a very aggressive price. For networking applications, the Gigabit Ethernet MACs support connectivity to the wired network while the PCI Express(R) and SDIO interfaces can offer connectivity to wireless LAN or 3G and 4G modem devices. The MPC8308 processor features integrated IEEE(R) 1588 time synchronization for applications such as time-sensitive telecommunications services, industrial network switches, powerline networks and test/measurement devices. All of these applications will be fully enabled with the MPC8308 processor and the low-cost evaluation board with optimized Linux(R) BSP and drivers. Freescale also works with thirdparty partners to enable application software for end user interfaces. These architectural enhancements enable Best-in-class power consumption Integrated Gigabit Ethernet, USB, SD/MMC controller, IEEE(R) 1588v2, PCI Express(R) interfaces MPC8308 Block Diagram e300 Core 16 KB I-Cache 16 KB D-Cache DDR2 SDRAM Controller Local Bus Coherent System Bus DUART, 2 x I2C, SPI, Timers, GPIO, Interrupt Control 2 x Gigabit Ethernet 2 x RGMII/MII PCI Express(R) USB 2.0 eSDHC Core Features High-performance e300 core, built on Power Architecture(R) technology, at 1.92 DMIPS/MHz Comprehensive third-party ecosystem Migration path Benefits High-efficiency core means less MHz needed to get the job done or extra CPU headroom to perform other tasks Faster time to market Improved performance/cost migrating from PowerQUICC(R) or PowerQUICC II. Common architecture eases migration. Enables fanless, "green" and low-cost designs, and improves reliability Allows the flexibility to address a wide range of applications and reduced system cost Core Complex The MPC8308 processor incorporates the e300c3 (603e core compatible) core at 266, 333 and 400 MHz with 1.92 DMIPS/ MHz. The core, built on Power Architecture(R) technology, includes dual integer units as well as a modified multiply instruction. more efficient operations to be executed in parallel, resulting in a significant performance improvement. The e300 core complex also includes 16 KB each of L1 instruction and data caches and on-chip memory management units (MMUs) with dual integer units and SP/DP FPU. Cost-Effective Package The MPC8308 processor is designed with a very low-cost 473-pin MAPBGA package at 0.8 mm pitch and 19 mm x 19 mm dimension. This smaller package dimension is suitable for small-footprint applications in single-board computing and other embedded networking applications.
