Description
Transceiver integration (default transmission mode, no pairing password, switchable reception mode)
Call function (receiving function)
Serial AT command control
Serial port AT modify the Bluetooth name (receive function)
Prompt tone (neutral tone = drop prompt or electronic tone) (receive function)
Support long press “MODE” button to shut down, short press “MODE” button to power on, power off is very low
All controls support serial AT commands and are very powerful
Low power, highly integrated Bluetooth system on chip (SoC) audio device.
It integrates a high performance Bluetooth RF transceiver, feature rich baseband processor, FLASH memory controller, multiple analog and digital peripherals.
Bluetooth software stack including the audio, voice, and SPP profiles.
The cache based architecture enables full programmability with an SIP 8M FLASH memory device and can be used for both control and multimedia hybrid applications.
The internal dual stereo ADC converts stereo analog input to digital signals that can be processed with a digital equalizer. Hardware realizations of the equalizer offload the MCU making the chip ideal for low power headset applications.
The device incorporates on-chip power management with linear and switch-mode buck regulators and also includes a 220mA internal battery charge controller to further reduce external bill of material (BOM) costs.
