Overview
The MPC8313E-RDB reference platform is ideal for hardware and software development for cost-optimized networking applications. The cost-effective MPC8313E communications processor family meets the requirements of several small office/home office (SOHO), printing, IP services and industrial control applications. It leverages Freescale’s highly integrated MPC8313E processor built on Power Architecture™ technology and leading-edge external components—a 5-port Gigabit Ethernet switch, USB port, one Peripheral Component Interconnect (PCI) slot, one MiniPCI slot and one SD card memory slot. The high level of integration in the MPC8313E helps to lower overall system costs, improve performance and simplify board design.
