Marvell is introducing several SoCs designed for low power consumption, network switching and security at the Interop IT Conference and Tradeshow in Las Vegas, for applications ranging from routers, base stations, storage, single-board computers to high-volume laser printers.

Low power MCUs
The MV78200 comprises dual ARM cores, while the MV78100 and MV76100 are single-core SoCs designed for more cost-sensitive applications, the company said. The products support processor speeds ranging from 800MHz to 1.2GHz and incorporate up to 512KB of L2 cache per core.

In addition, the SoCs have integrated PCIe interfaces that support four lanes of data, multiple USB 2.0 and GbE ports, and a security engine.

Marvell offers development platforms for the new products, as well as reference designs that include software drivers and support packages for VxWorks and Linux operating systems. Samples of the SoCs are available for hardware manufacturers.

Enterprise network switching
Other show introductions planned by the chipmaker include two SoCs for network switching that the company says bring carrier-grade availability to enterprise networks. The Prestera 98DX2100 and 98DX4100 are tailored for various types of high-speed broadband access, including PON, VDSL, and Ethernet. The processors' flexibility is because of a versatile set of programmable interfaces, Marvell said.

To support network upgrades, the devices integrate four FlexUplink ports programmed to support upgrades from 1Gbit/s to 2.5Gbit/s to 10Gbit/s. To minimize power dissipation and save on overall system cost, the products have a built-in controller for high-speed 800M DDR2 memory and low-cost NAND flash.

Marvell is sampling the 98DX2100 and 98DX4100 processors. Pricing was not disclosed.

Switching for security
To boost security on a wireless LAN, Marvell is introducing switching technology it calls LinkCrypt, which can be embedded across a broad number of products on an Ethernet network. Based on the IEEE 802.1AE standard, the technology enforces authentication on each device on the network.

Traffic sent over a LinkCrypt-secured network is encrypted and authenticated to prevent a network node from hijacking the address of another node or lying about its own, according to Marvell.

Finally, in the telecom area, Marvell is introducing what it calls CarrierSpan technology for metro Ethernet and carrier networks. Embedded within Marvell's SoCs for network switching, the technology offers hardware assistance in service delivery to help ensure uninterrupted uptime. CarrierSpan targets manufacturers building equipment for networks that provide multiple services, such as video, voice, and broadband, to hundreds of thousands of subscribers.
