Built-in internal ROM for program memory
Support to connect to two hosts ( phones,
tablets…) with HFP or A2DP profiles
simultaneously
Adaptive Frequency Hopping (AFH) avoids
occupied RF channels
Fast Connection supported
RF Hardware
Fully Bluetooth 4.1 (EDR) system in 2.4 GHz
ISM band.
Combined TX/RX RF terminal simplifies
external matching and reduces external
antenna switches.
Max. +4dBm output power with 20 dB level
control from register control.
Built-in T/R switch for Class 2/3 application

Description
Stereo Audio Chip is a compact, highly
integrated, CMOS single-chip RF and
baseband IC for Bluetooth v4.1 with Enhanced
Data Rate 2.4GHz applications. This chip is
fully compliant with Bluetooth specification and
completely backward-compatible with Bluetooth
3.0, 2.0 or 1.2 systems.
It incorporates Bluetooth 1M/2M/3Mbps RF,
single-cycle 8bit MCU, TX/RX modem, 5-port
memory controller, task/hopping controller,

UART interface, and MICROCHIP’s own
Bluetooth software stack to achieve the
required BT v4.1 with EDR functions.
To provide the superior audio and voice
quality, it also integrates a DSP co-processor, a
PLL, and a CODEC dedicated for voice and
audio applications.
For voice, not only basic CVSD encoding and
decoding but also enhanced noise reduction
and echo cancellation are implemented by the
built-in DSP to achieve better quality in both
sending and receiving sides. For the enhanced
audio applications, SBC/AAC_LC decoding
functions can be also carried out by DSP to
satisfy Bluetooth A2DP requirements.
In addition, to minimize the external
Stereo Audio SoC
components required for portable devices, a
battery voltage sensor, battery charger, a
switching regulator and LDO are integrated to
reduce system BOM cost for various Bluetooth
applications.
As the market of portable/wireless speakers
demand is increasing, a stereo 2 channels
2.3W class-D amplifier which provides up to
100dB SNR is also built-in to reduce BOM cost
and PCB area.
Applications
Stereo headsets
Portable speakerphones
