The MPC8321 PowerQUICC II Pro is part of the MPC8323E family of cost-effective network communication processors that meet the requirements of several small office/home office (SOHO), broadband access, routers and industrial control applications. It provides better CPU performance, additional functionality and faster interfaces than current PowerQUICC processors while addressing important time to market, price, power consumption and board real estate requirements.e300 core with dual integer units enables more efficient operations to be conducted in parallel, resulting in significant performance improvementThe single-RISC QUICC Engine communications block offers a future-proof solution for next-generation designs by supporting programmable protocol termination and network interface termination to meet evolving protocol standardsDDR-1/DDR-2 memory controller—one 32-bit interface operating at up to 266 MHz supporting both DDR-1 and DDR-2Peripheral interfaces such as 32-bit, 66 MHz PCI, 16-bit, 66 MHz local bus interface and USB 2.0 (full/low-speed)High degree of software compatibility with previous-generation PowerQUICC processor-based designs for backward compatibility and easier software migration
