RDA5872P

SINGLE CHIP FOR BLUETOOTH Rev.1.11–03.2011



1 General Description

RDA5872P 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.

RDA5872P provides UART which is specified as

HCI interfaces by Bluetooth SIG standard, and

also supports PCM audio interface.

RDA5872P has been designed on highest level of

integration to extremely reduce the number of

external component. It uses CMOS process with a

compact 6*6mm 40-pin QFN package.
