特性:

RDA5870 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 RDA5870 on their
product to enable a rapid time to market.
RDA5870 uses CMOS process with a compact
6*6mm 40-pin QFN package.
