RDA5876P
SINGLE CHIP FOR BLUETOOTH & FM RADIO TUNER
Rev.1.11–08.2012
1 General Description
RDA5876P 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 RDA5876P on their
product to enable a rapid time to market.
RDA5876P uses CMOS process with a compact
4*4mm 32-pin QFN package.

Power Supply
The RDA5876P FM section integrated LDO which
supplies power to the chip. The external supply
voltage range is 1.8-5.5 V.
RESET and Control Interface select
The RDA5876P FM section is RESET itself When
VIO is Power up. And also support soft reset by
trigger 02H BIT1 from 0 to 1. The control interface
is I2C.
Control Interface
The I2C interface is compliant to I2C Bus
Specification 2.1. It includes two pins: SCL and
SDA. A I2C interface transfer begins with START
condition, a command byte and data bytes, each
byte has a followed ACK (or NACK) bit, and ends
with STOP condition. The command byte includes
a 7-bit chip address (0010000b) and a R/W bit.
The ACK (or NACK) is always sent out by receiver.
When in write transfer, data bytes is written out
from MCU, and when in read transfer, data bytes
is read out from RDA5876P. There is no visible
register address in I2C interface transfers. The
I2C interface has a fixed start register address
(0x02h for write transfer and 0x0Ah for read
transfer), and an internal incremental address
counter. If register address meets the end of
register file, 0x3Ah, register address will wrap
back to 0x00h. For write transfer, MCU programs
registers from register 0x02h high byte, then
register 0x02h low byte, then register 0x03h high
byte, till the last register. RDA5876P always gives
out ACK after every byte, and MCU gives out
STOP condition when register programming is
finished. For read transfer, after command byte
from MCU, RDA5876P sends out register 0x0Ah
high byte, then register 0x0Ah low byte, then
register 0x0Bh high byte, till receives NACK from
MCU. MCU gives out ACK for data bytes besides
last data byte. MCU gives out NACK for last data
byte, and then RDA5876P will return the bus to
MCU, and MCU will give out STOP condition.

Guide and RDA5802N Programming Guide and
Datasheet.
