Abstract
A method and system for a single chip integrated Bluetooth and FM transceiver and baseband processor are provided. The single chip may comprise a Bluetooth radio, an FM radio, a processor system, and a peripheral transport unit (PTU). FM data may be received and/or transmitted via the FM radio and Bluetooth data may be received and/or transmitted via the Bluetooth radio. The FM radio may receive radio data system (RDS) data. The PTU may support digital and analog interfaces. A processor in the processor system may time-multiplex processing of FM data and processing of Bluetooth data. The single chip may operate in an FM-only, a Bluetooth-only, and an FM-Bluetooth mode. The single chip may reduce power consumption by disabling portions of the Bluetooth radio during FM-only mode and/or disabling analog circuitry when performing digital processing. Communication between Bluetooth and FM channels may be enabled via the single chip.
