PMC-Sierra RM9000 Family Expands with Multiple I/O Interfaces

6/18/2003 - PMC-Sierra(TM), Inc. (Nasdaq: PMCS - News) announced two RM9000x2GL highly integrated 1 GHz 64-bit MIPS-based(TM) multiprocessors, the RM9220 and RM9224. The RM9000x2GL multiprocessors offer customers additional I/O interface options such as 3 ports of 10/100/1000 Ethernet MAC, Generic Packet Interfaces (GPI), and PCI or HyperTransport(TM). As a result, the RM9000x2GL multiprocessors can be used in a wider range of applications such as enterprise routers and switches, network protocol processing and conversion servers, storage systems, DSLAMs and Web servers. The dual-core devices can also be used as a high-performance and compact solution for VPN/ Firewall and other security applications in conjunction with appropriate encryption engines.

"The RM9000x2GL builds upon our successful RM9000x2 MIPS-based dual CPU core architecture. The addition of multiple I/O interfaces provides us with the ability to meet design requirements in a broader customer base. Our RM9000x2 multiprocessor was originally designed for control and data plane networking applications and the RM9000x1 for storage and wireless markets. Now with the RM9000x2GL we are pleased to be able to design our RM9000 family of products into over a dozen types of applications," said Tom Riordan, vice president and general manager of PMC-Sierra's Microprocessor Products Division. "PMC-Sierra offers the industry's most scalable, stand-alone MIPS-based processors and we are committed to extending our RM5200, RM7000 and RM9000 families with higher integration and performance while maintaining low power."

Integrates Enhanced High-Speed Memory and Multiple I/O Interfaces
The RM9000x2GL integrates high-speed memory and I/O interfaces to create low latency accesses into the main memory and high bandwidth to the I/O devices. The I/O interfaces include three Ethernet MACs, PCI or HyperTransport, DDR SDRAM controller, SysAD and a local boot bus:

Pricing, Availability and Customer Support
The RM9000x2GL microprocessors are available in two packages (see table 1) and will be sampling in the fourth quarter of 2003. Both processors are designed in 0.13 micron CMOS and can achieve a low power of 12 watts in a typical networking application with all I/O running at maximum frequency. Pricing for the RM9220 and RM9224 processors range from $379 to $389 in 10KU quantities. For more information about pricing and availability, contact a PMC-Sierra sales representative at Evaluation boards will also be available in the fourth quarter of 2003.

RM9000 MIPS-based Processors Compatible with Industry Standards
The MIPS(TM) architecture has become one of the most widely licensed, open-industry standard architectures in networking, networked printer and networked consumer applications. A wide range of development tools and resources are available through a large number of third-party development partners. The RM9000 family of processors will support multiple operating systems such as Linux and Wind River's VxWorks®. A variety of packaged systems for software development or for full product deployment are currently available through Momentum Computer. These packaged systems provide operating systems, compilers, debuggers, RTOS and peripheral support for HyperTransport. The on-chip EJTAG debug module ensures smooth and easy debugging of both hardware and software by allowing a single step and state examination.
