All-CMOS Radio and Baseband Chips for Bluetooth

The Blutonium family consists of a high-performance Bluetooth radio and two baseband processors targeted at specific applications, providing complete end-to-end Bluetooth solutions. The BCM2001 is a high-performance Bluetooth radio manufactured in a standard digital CMOS process. The line also includes two baseband processors, the BCM2039 for applications requiring a standard Bluetooth interface and the BCM2019 for a more flexible interface to the host controller.

Used with the BCM2001 radio, each baseband processor provides the basis for a wide variety of Bluetooth system solutions. Designed in digital CMOS, the Blutonium product line provides a clear integration path to a single-chip Bluetooth solution incorporating both RF and baseband sections.

Providing radio performance that exceeds Bluetooth 1.1 specifications, the BCM2001's robust architecture is optimized to provide a strong balance between receiver sensitivity and interference rejection. By integrating all filters and eliminating most off-chip components, the radio offers the smallest footprint, thereby enabling small portable consumer products. BCM2001 samples are available now.

The BCM2039 is a stand-alone baseband controller for applications requiring a full, end-to-end Bluetooth solution. The chip provides all controller functions, including the protocol stack up to the Logical Link Control and Adaptation Protocol (L2CAP). This Host Controller Interface (HCI)-compliant solution supports point to point and multipoint connectivity, integrating several interfaces, including USB and high-speed UART. The BCM2039 is compliant with version 1.1 of the Bluetooth specification, featuring low power consumption and integrated memory, requiring no off-chip flash. BCM2039 samples are available now in a 100-pin FPBGA package.

The BCM2019 host-based controller represents a novel repartitioning of the Bluetooth architecture, providing a lower-cost baseband solution optimized for systems with the processor and memory already present in a host device. The highly flexible BCM2019 provides the ability to upgrade baseband software as future versions of the Bluetooth protocol become available. This architecture streamlines the standard Bluetooth protocol stack, minimizing the Bluetooth-specific hardware required in other baseband solutions. In addition, the device's use of memory on the host means that no external flash is required. BCM2019 samples are available now in a 48-pin PQFP package.
