Freescale Semiconductor Inc. has introduced the MPC8313E PowerQUICC II Pro processor with integrated security. The new device is said to address the market demand for inexpensive processors that can securely distribute and process multiple streams of multimedia content throughout the home.

The MPC8313E integrates a combination of GbE, USB 2.0, high-speed interconnect and advanced power management technologies to provide a suitable platform for a variety of consumer applications, including residential gateways, IEEE 802.11n access points, digital media servers, network access storage devices and printers.

Digital home tech
The cost-effective device meets a number of critical requirements for digital home technology including piracy protection, QoS and ease-of-use features. The processor also helps enable the creation of end devices compliant with the Digital Living Network Alliance (DLNA) standard, which makes it easy for consumers to manage, view, print and share digital content across multiple devices within the home.

The MPC8313E eases the deployment of a wide range of high-speed peripherals at an extremely affordable price point. In addition to GbE and USB2.0 with phy integration, the MPC8313E provides a 32bit double data rate (DDR1/DDR2) memory controller running up to 333MHz, a 32bit PCI controller, a 16bit local bus and four direct memory access (DMA) channels. The device's integrated security engine leverages Freescale's extensive encryption technology portfolio. (The "E" in the MPC8313E product name designates on-chip encryption.)

Powered by the latest generation of Freescale's e300 core based on Power Architecture technology, the MPC8313E processor runs at speeds up to 333MHz and delivers up to 700MIPS, enabling deployment of feature-rich applications and high-performance peripherals. The device incorporates on-chip memory management units (MMUs) and 16Kbyte of L1 instruction and data caches.

Compatible with PowerQUICC II devices and other legacy PowerQUICC parts, the MPC8313E helps to reduce overall BOM. It speeds time-to-market through maximum reuse of code, integration of key peripherals, the availability of cost-effective reference designs and a robust third-party ecosystem of development tools and application software support.

Because the integrated security engine offloads compute-intensive cryptographic operations from the main CPU, the device's extensive encryption technology does not impact throughput performance. The security processing unit provides hardware acceleration for the DES, 3DES, Advanced Encryption Standard (AES), Secure Hash Algorithm (SHA-1) and MD-5 algorithms.

IEEE 1588
The MPC8313E supports the IEEE 1588 timing protocol, which is essential for industrial control and test and measurement applications. For LAN control and switching applications, the MPC8313E offers a SGMII serial interface for GbE controllers. Additional applications supported by MPC8313E include a line card controller, broadband router, intelligent NIC, integrated access devices and 802.11n wireless LAN access points.

The device meets strict power regulations and supports ACPI standards. It includes power management features such as smart-wakeup functionality and exceptionally low standby power at less than 300mW.

The MPC8313E is available in a 516-pin PBGA package and is manufactured using Freescale's 90nm process technology, enabling 1V core voltage and 3.3V I/O.

Freescale also announces an optimised derivative called the SC8311, which is designed exclusively for printing and imaging markets. Based on the MPC8313, the SC8311 is a cost-effective SoC that helps manufacturers offer highly advanced, full-featured laser printers at low price points. The SC8311 features advanced low-power capabilities that help manufacturers meet emerging power regulations in European and Japanese markets.

Initial samples of MPC8313E are available today, and general samples are expected Q1 2007. General availability is scheduled Q2 2007. Suggested retail pricing begins at $15 for 10,000 quantities.
