OCTEON II CN66XX Family of Multi-Core MIPS64 Processors

6 to 10 cnMIPS64 v2 cores processors for high-volume applications in enterprise routers, switches, appliances, basestations, and storage and server adapters up to 15+Gbps

OCTEON II CN66XX Multi-Core MIPS64 Processors

The Marvell® OCTEON® II CN66XX family of multi-Core MIPS64 internet application processors targets high-performance, high-volume applications in enterprise routers, switches, control plane applications, appliances, 3G/4G basestations, and intelligent storage and server adapters. The family is comprised of four software and pin-compatible processors, with six to ten cnMIPS64 v2 cores at up to 1.5GHz speed on a massively integrated SoC. It includes the latest SERDES-based I/Os including PCIe Gen2, XAUI, and sRIO, along with advanced third-generation application hardware acceleration. CN66XX processors deliver over 15Gbps application performance.

The CN66XX provides high performance integration for next-generation 3G/4G/LTE wireless basestation platforms, providing up to 15GHz of compute with a large 2MB L2 cache, DDR3 memory controller, security acceleration for SNOW 3G and KASUMI, TCP/IP packet processing acceleration, and QoS. PowerOptimizer™ technology limits maximum power from 9 to 20 watts from low-end to high-end.

Supported by industry-standard software toolchains and operating systems, the CN66XX is both footprint and software compatible with CN63xx enabling customers a seamless migration for 2x performance enhancement.
