The MPC83xx series low-power PowerQUICC II Pro Processor with DDR2, TDM, PCI and PCI express interfaces. The MPC8315E incorporates the e300c3 (MPC603e-based) core, which includes 16kB of L1 instruction and data caches, on-chip memory management units (MMUs) and floating-point support. In addition to the e300 core, the SoC platform includes features such as dual enhanced three-speed 10, 100, 1000Mbps Ethernet controllers (eTSECs) with SGMII support, a 32- or 16-bit DDR1/DDR2 SDRAM memory controller, dual SATA 3Gbps controllers (MPC8315E-specific), a security engine to accelerate control and data plane security protocols and a high degree of software compatibility with previous-generation PowerQUICC processor-based designs for backward compatibility and easier software migration. The MPC8315E also offers peripheral interfaces such as a 32-bit PCI interface with up to 66MHz operation, 16-bit enhanced local bus interface with up to 66MHz operation and TDM interface.
