RDA5872
SINGLE CHIP FOR BLUETOOTH Rev.0.92–Apr.2010
1 General Description
RDA5872 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 appli cation.
RDA5872 provides UART which is specified as
HCI interfaces by Bluetooth SIG standard, and
also supports PCM audio interface.
RDA5872 has been de signed on highest level of
integration to extremely reduce the number of
external component. It uses CMOS proc ess with a
compa ct 6*6 mm 40-pin QFN package. Figure1-1. RDA5872 Top View
