MSP8210
Multi-Service Processor
Preliminary Product Brief
Product Overview
PMC-Sierra’s MSP8210 Multi-Service Processor is designed to meet
the needs of networking, network attached storage appliances
and embedded applications.
The MSP8210 is part of the MSP8200 Series of highly-integrated,
feature-rich products that incorporate the high performance,
power-efficient, MIPS 34K core. The processor provides a PCI
interface, three Ethernet ports, two USB ports, ROM, Flash, DDR,
and low-speed peripheral interfaces, all connected internally to
the MIPS 34K by a high-bandwidth multi-service bus.
