SINGLE CHIP FOR BLUETOOTH RDA5875 Rev.1.0–11.2010 1 General Description RDA5875 is a highly integrated single-chip IC with radio transceiver and baseband processor, which is compliant with Bluetooth 2.1 + EDR specification and provides an optimal solution for data and voice application. RDA5875 provides UART which is specified as HCI interfaces by Bluetooth SIG standard, and also supports PCM audio interface. RDA5875 has been designed on highest level of integration to extremely reduce the number of external component. It uses CMOS process with a compact 44mm 32-pin QFN package. Figure1-1.
