Broadcom Corp. unveils an ARM Cortex A9-based HSPA 3G base band processor, the BCM21654 that supports high-end 3D graphics support and advanced processing targeting mass-market Android handsets.

Made with a 40nm CMOS process, the processor provides mainstream smart phones with better graphics and user interface performance. It also includes built-in support for Android 2.3 and future releases.

By combining the BCM21654 base band processor with other Broadcom products such as the BCM2091 RF IC or the BCM59039 advanced power management unit with charger and audio support it is possible to create a complete Android smart phone platform solution. It brings the Cortex A9 processing power and extensive connectivity support into low cost 3G Android handsets.

The features that are driving smart phone demand include the ability to run apps, view and share media, and enjoy a dynamic touch-screen experience.

The Broadcom BCM21654 base band processor for Android smart phones also feature an ARM Cortex R4 communications processor; integrated 3G HSPA modem that supports 7.2Mbit/s of downstream connectivity, 5.8Mbit/s upstream, as well as Class 32 EDGE support for greater flexibility and worldwide roaming; and dual-SIM capabilities that allow consumers to use the same handset for two different phone numbers or accounts, enabling applications such as access to work and personal cellular calls with one handset.

The VideoCore IV mobile multimedia processor core delivers high-end smart phone capabilities with 30fps of playback and support for full-rate video standards such as H.264 at high-quality VGA resolution. It has a 3D graphics engine that enables up to 20 million triangles per second; a 12 megapixel (JPEG) camera; and support for 16 million colours, up to WVGA, and dual-displays.

Broadcom's complete connectivity suite features industry-leading Bluetooth, Wi-Fi and GPS solutions, all supported by InConcert technology that makes these various radio technologies work better together and with less interference.
