MPC8306

Integrated Communications Processors MPC8306 and MPC8306S PowerQUICC II Pro Processors Overview The MPC8306 and MPC8306S processors are part of the ultra low-end MPC830x communications processor portfolio based on the e300 core architecture. They address the requirements of networking applications, including I/O cards for low-end base stations, residential gateways, modem/routers, industrial control, factory automation and test and measurement applications. The MPC830x portfolio extends current PowerQUICC offerings, providing similar DMIPS/MHz in CPU performance, additional functionality and faster interfaces while maintaining code compatibility with PowerQUICC I and PowerQUICC II processors. MPC830x processors also provide competitive pricing, low power consumption, compact board footprint and a time to market advantage through cost-effective evaluation kits with optimized BSP and drivers. Power Architecture® technology, which includes 16 KB of L1 instruction and data caches, dual integer units and on-chip memory management units (MMUs). USB 2.0 controller, a 16-bit local bus and two direct memory access (DMA) channels. In addition, the MPC8306 also features 4 x CAN and an enhanced SDHC controller. In summary, the MPC8306S and MPC8306 devices provide users with a highly integrated, fully programmable communications processor for use in many networking and industrial control applications. This helps ensure that a cost-effective system solution can be quickly developed and will offer flexibility to accommodate new standards and evolving system requirements. QUICC Engine Technology A communications complex, based on QUICC Engine technology, forms the heart of the networking capability of the MPC830x portfolio. The QUICC Engine block contains several peripheral controllers and a 32-bit RISC controller. Protocol support is provided by the main workhorses of the device—the unified communication controllers (UCCs). Each of the five UCCs can support a variety of communication protocols, including 10/100 Mbps Ethernet and high-level data link control (HDLC). Two of the UCCs can also support IEEE® 1588 version-2 time stamping (MPC8306 configuration only).
