RDA5869 Data Sheet
Bluetooth® Single-Chip for Headset/hand-free applications
Rev.1.3–10.2012
1 General Description
The RDA5869 is a highly-integrated mixed-signal
SOC integrated with 2.4GHz RF transceiver
compliant with Bluetooth core 2.1 and ARM7-based
microprocessor baseband. It is ideal for wireless
headset/hand-free device applications
The radio part of RDA5869 has been designed to
provide low power, low cost, and robust applications
for communications in the globally available 2.4 GHz
unlicensed ISM band.
This single-chip RDA5869 is implemented in a
standard digital 55nm CMOS process technology
and requires minimal external components to
provide total solutions especially for headset
applications. The chip is packaged as 32- pin, 4 mm
× 4 mm QFN.
