The MPC8349E PowerQUICC II™ Pro family of integrated communications processors is a next-generation extension of the popular PowerQUICC II line. Based on a system-on-chip (SoC) architecture, the MPC8349E PowerQUICC II Pro Family integrates the enhanced e300 core and advanced features, such as DDR memory, Dual Gigabit Ethernet, Dual PCI and Hi-Speed USB controllers. With clock speeds scaling to 667 MHz, the MPC8349E family of processors offers the highest performing PowerQUICC II devices available.

The MPC8349E PowerQUICC II Pro Family is designed to provide a cost-effective, highly integrated control processing solution that addresses the emerging needs of networking, communications and pervasive computing applications. MPC8349E processors can be used in applications such as Ethernet routers and switches, wireless LAN (WLAN) equipment, network storage, home network appliances, industrial control equipment, and copiers, printers and other imaging systems.

e300 SoC Platform
The MPC8349E PowerQUICC II Pro Family is based on the e300 SoC platform—making it easy and fast to add or remove functional blocks and develop additional SoC-based family members targeting emerging market requirements. At the heart of the e300 SoC platform is Freescale Semiconductor´s e300 core. Based on the classic instruction-set architecture, the e300 core is an enhanced version of the 603e core used in previous-generation PowerQUICC II processors. Enhancements include twice as much L1 cache (32 KB data cache and 32 KB instruction cache) with integrated parity checking, and other performance-enhancing features. The e300 core is completely software-compatible with existing 603e core-based products.

Integrated Security
The MPC8349E Family features a powerful integrated security engine derived from Freescale Semiconductor´s security coprocessor product line. The MPC8349E Family´s security engine supports DES, 3DES, MD-5, SHA-1, AES, and ARC-4 encryption algorithms, as well as a public key accelerator and an on-chip random number generator. The security engine is capable of single-pass encryption and authentication, as required by IPsec, IEEE® 802.11i standard and other security protocols.
