RIM To Offer BlackBerry Reference Design Program To Device Manufacturers

Analog Devices, Inc. Plans To Provide Wireless Communications and Applications Processor Chip For RIM's New Reference Design Program

Waterloo, ON - Research In Motion Limited (RIM) (Nasdaq: RIMM; TSE: RIM) today announced plans to offer a BlackBerry™ reference design program that will provide other manufacturers with a comprehensive hardware and software platform for building advanced wireless phones and handheld devices based on embedded BlackBerry and Java technologies. As part of the reference design program, Analog Devices, Inc. (NYSE: ADI) plans to provide participating manufacturers with an integrated processor that supports both wireless communications and Java applications on a single chip. Custom designed for RIM, this new processor is based on ADI's SoftFone® architecture and specifications from RIM for optimal system performance on GSM/GPRS wireless networks.

"RIM has been focused on wireless data technology and integration since 1988. Our experience and success in this market allows the unique ability to offer a reference design program that will provide device manufacturers with solutions and tools to quickly and easily deliver carrier-ready wireless devices and Java applications based on the popular and proven BlackBerry solution," said Mike Lazaridis, President and Co-CEO at Research In Motion. "As part of this initiative, RIM will work with leading companies to develop advanced technologies that will support the reference design program and provide device manufacturers and carriers with innovative, effective and timely wireless solutions."

BlackBerry has been implemented in over 13,000 organizations in North America and Europe and RIM has developed strong relationships with leading network operators worldwide. RIM's reference design program will leverage this success and provide manufacturers with a standardized foundation to accelerate and simplify the design and deployment of wireless devices such as next-generation PDAs, cell phones and other wireless Internet handhelds. RIM will also provide manufacturers with the professional services needed to expedite component integration, application development and interoperability testing and certification. Based on an open Java platform, manufacturers and carriers will be able to add additional applications and services in conjunction with a growing development community that already includes over three million Java developers. The reference designs, based on the certified and proven Java-based BlackBerry platform, will be designed to enable the rapid development of high-quality wireless devices and benefit the overall industry including manufacturers, carriers, developers and customers.

RIM's new initiative with ADI is focused on providing device manufacturers with a powerful chip that integrates DSP (Digital Signal Processing) and microprocessor functionality into a single chip. This chip will enable manufacturers to build next-generation devices for advanced GSM/GPRS wireless networks with considerable advantages in terms of size, cost, power consumption and time-to-market.

"RIM's expertise in wireless data communications fits well with ADI's leadership in providing highly integrated chips and chipsets for wireless applications. ADI is pleased to continue our long-standing relationship as a wireless component supplier to RIM by providing a highly integrated solution that combines baseband and applications processing in a single chip," said Brian McAloon, Group Vice President and General Manager, DSP and System Products, Analog Devices, Inc. "The BlackBerry reference design will provide wireless handset manufacturers with a real time-to-market advantage over other competitive alternatives in the GSM/GPRS market place, as well as significant advantages in power, area and cost. In addition, the availability of a powerful embedded Java engine on this platform opens up enormous potential for easy applications development and rollout, supporting value added services over the network. The ability to offer network services that customers will pay for is critical for service providers operating 2.5G networks."

Further information regarding the details and availability of RIM's reference design program will be announced at a later date.
