Compatible with V4.2/V4.2 LE/V3.0/V2.1+EDR Systems;
Storage: Built-in ROM, SPI Flash and 156K bytes RAM;
Communication interface: UART, I2C
Audio output: 16bit
Two-channel stereo, 18mW PA, optional differential or single-ended output, I2S TX;
Audio input: MIC, AUX;
PIN resources: 9 GPIO, 5 PWM, 4 LRADC;
Integrated charge management, 10mA-300mA charging current is optional;
Support Bluetooth sbc, Bluetooth call (msbc), bilateral call, HID camera control and other application scenarios, support dual mobile phone connection (1 drag 2);
Support sound adjustment of scenes such as songs and calls, 14-segment PEQ, limiting and pre-attenuation; support fade-in, channel mixing, channel switching and other post-processing;
Support call PLC, AEC, AGC, ANS, CNG and other algorithm adjustment;
Support the charging box to pick up the boot function. When the headset is full, the output voltage of the charging box can be lowered to pick up the boot. When the output voltage of the charging box is 5V, the standby current of the earphone is 50uA; when the output voltage of the charging box is 2.5V, the standby current of the earphone is <10uA.
