The Broadcom BCM2035 is a monolithic single-chip, stand alone baseband processor with an integrated 2.4-GHz transceiver for Bluetooth 1.1 and 1.2 applications. It eliminates the need for external flash memories and active components by integrating critical components into the device, thus minimizing the footprint and system cost of implementing a Bluetooth system.
