PowerQUICC™ enhancements deliver cost-effective enhanced storage

The MPC8315E is the newest member of the Freescale Semiconductor PowerQUICC II Pro family. The MPC8315E communications processor integrates an array of technologies essential for storage markets, including SATA, PCI Express, USB 2.0, and Gigabit Ethernet interfaces, XOR acceleration and high-performance security functionality.

The MPC8315E is suited to consumer Small- Office/Home-Office (SOHO) storage and media-server markets. The integrated dual SATA controller supports both 1.5Gbit/s SATA and 3.0Gbit/s SATA 2.0 drives. RAID 0 striping and RAID 1 mirrored storage are both supported, with acceleration from the integrated XOR engine.

The MPC8315E processors are available in 266MHz, 333MHz and 400MHz speeds, and include 16kbyte instruction and 16kbyte data caches. Lower cost variants are the MPC8314E, which does not include the SATA interface, and the MPC8315 and MPC8314, which do not include the security engine.

All variants include hardware support for IEEE 1588 clock synchronisation in industrial applications.

The MPC8315E and MPC8314E are Freescale’s lowest cost processors to include integrated PCI Express. All variants include dual single-lane PCI Express 1.0a interfaces each operating at 250Mbytes/s bi-directional speed. All Freescale’s PowerQUICC processors are supported by third-party hardware and software partners offering development tools and systems, as well as middleware and software stacks.

The built-in security engine in the MPC8315E and MPC8314E is designed to offload intensive security functions from the main processor, such as key generation and exchange, authentication and bulk encryption. The engine is optimised for algorithms associated with IPsec, IKE, SSL/TLS, IEEE 802.11i, 802.16 WIMAX and the 802.1AE Media Access Control Security (MACSec) standards.
