MPC8323E-RDB reference design board


The MPC8323 reference platform (MPC8323E-RDB) is a turnkey hardware/ software reference platform designed to rapidly provide the core elements of tomorrow’s multi-service gateway products. The MPC8323E-RDB leverages the processing power of the MPC8323E PowerQUICC II Pro integrated communications processor. Built on Power Architecture™ technology, the MPC8323E family of products integrates a proper balance of architectural features (e300 core, dual integer units, 16 KB instruction and 16 KB data caches) along with a DDR 1/2 memory controller, RISC-based communications engine (QUICC Engine™) and an optional H/W security engine.
