The Broadcom BCM2048 is a monolithic 0.13 um single-chip Bluetooth® 2.0 +EDR compliant stand-alone baseband processor with an integrated 2.4-GHz transceiver, integrated FM and RDS/RBDS receiver, and an integrated FM baseband processor. It features the highest level of integration and eliminates all critical external components, thus minimizing the footprint and system cost of implementing a Bluetooth and FM solution. The BCM2048 is firmware upgradeable to future specifications.
The BCM2048 is the optimal solution for any voice and/or data application that requires the Bluetooth SIG standard Host Controller Interface (HCI) via a high-speed UART and PCM. The BCM2048 incorporates all Bluetooth 2.0 +EDR features including eSCO, AFH, fast connect, all EDR packet types and lengths, and all errata. The BCM2048 also includes InConcert and other industry collaborative coexistence solutions with WLAN systems.
