RDA5876A integrates industry-lead Bluetooth and FM radio tuner into one chip and is optimized for mobile applications. Bluetooth and FM can work simultaneously and independently, with low power consumption levels target to battery powered devices. For the highest integration level, the required board space has been minimized and customer cost has been reduced. Manufacturers can easily and fast integrate RDA5876A on their product to enable a rapid time to market.

RDA5876A uses CMOS process with a compact 4*4mm 32-pin QFN package.
