Broadcom Corp. announced a new single-chip HSPA baseband processor and a RF transceiver solution that integrates all of the key 3G cellular and mobile technologies for powering the 3G smart phone and smart feature phone product segments.

The advanced baseband processor is the first to provide extremely high-speed cellular connectivity with advanced, built-in graphics capabilities, for HSUPA applications. The RF transceiver solution complements the advanced HSUPA processor to provide support for all global frequency combinations covering the latest 3G-enabled devices.

Designed in Broadcom's proven 65nm CMOS process, the new '3G phone-on-a-chip' and RF solution enables manufacturers to build low-cost, low-power, next-generation 3G HSUPA phones with breakthrough features, sleek form factors and very long battery lives. Utilizing an integrated ARM11 processor that is capable of running popular open operating systems (such as Windows Mobile and Android), the Broadcom BCM21553 HSUPA baseband processor can run innovative new applications and download media files at a much faster speed, resulting in sophisticated and affordable handsets, and a more satisfying smart phone experience.

Smart phones and smart feature phones continue to grow in popularity, with users attracted by the ability to download and use new software applications and view rich multimedia content. Highlighting the growing preference to use these phones for wirelessly accessing data, ABI Research projects over 350 petabytes of data will be transferred using smart phones in 2010, which is roughly equivalent to 3x as much information as is contained in the Library of Congress.

The Broadcom BCM21553 baseband processor enables the next generation of smart phones by supporting 3GPP releases 6 and 7, which provide up to 5.8Mbit/s of upstream connectivity, 7.2Mbit/s of downstream connectivity and support next generation circuit switches over HSPA services.

The baseband processor includes Broadcom PRISM (programmable interference suppression module) technology, which mitigates interference from radio signals emanating from neighboring cells, to provide higher performance gains in high interference environments where they're needed the most. It also integrates a high performance 3D graphics core with full support for the OpenGL ES 2.0 graphics standard, providing rich 2D and 3D graphics for applications and advanced user interfaces.

Open OS support is a key requirement for today's 3G smart phones, making these devices available to a broader range of software developers and innovative applications. By taking an Open OS approach, phones based on Broadcom technology can provide more mobile applications to users and an even better user experience.

The BCM21553's integrated high performance ARM11 processor can support Windows Mobile and Android open operating systems, eliminating the need for an external applications processor, which in turn saves size and cost, reduces system complexity, and improves battery life for 3G handset devices.

The powerful graphics core built into the BCM21553 baseband processor is based on Broadcom's advanced multimedia technology, providing video support up to HVGA quality, an 8Mpixel camera, and the ability to encode and decode H.264 video at 30 fps.

Also introduced by the company today is the Broadcom BCM2091 RF transceiver that provides RF connectivity for the BCM21553 HSUPA processor, enabling the industry's smallest HSPA transceiver designed in a standard low cost, 65nm CMOS process. The BCM2091 RF transceiver delivers a highly flexible architecture that provides handset designers with ultimate flexibility in PCB board design and reuse across the various cellular band and mode configurations required worldwide. It also reduces external RF engine component count by more than 40 percent over existing RF engines in production today, which in turn reduces BOM cost.

Jim Tran, VP and general manager, Broadcom's mobile communications line of business said, "With the introduction of our new BCM21553 HSUPA baseband processor and BCM2091 RF transceiver solutions, we are now enabling a new generation of increasingly affordable handsets that will offer the fastest cellular connectivity available, as well as the most popular smart phone features including wireless connectivity and diverse mobile applications."

The BCM21553 broadband processor and the BCM2091 RF transceiver are now available. Pricing is available upon request.

A fully proven and tested reference design, including other leading Broadcom connectivity solutions (such as Bluetooth, WLAN, GPS and FM), will also be provided.
