Tacent Bk3266 Ble 4.2 Latency A2DP AVRCP HFP HID AVCTP AVDTP SPP Shutdown Wireless Module For Stereo Speaker Headset

Tacent Bk3266 Bluetooth-Compatible 4.2 Latency A2DP AVRCP HFP HID AVCTP AVDTP SPP Shutdown Wirele Module For Stereo Speaker Headset

Master BK3266 version V5.0 stereo audio nsmitter and receiver integrated module, customized in batch

1. nsceiver integration (default nsmiion mode, no pairing paword, switchable reception mode)2. Call function (receiving function)3. Serial AT command control4. Serial port AT modify the BLE name (receive function)5. Prompt tone (neul tone = drop prompt or electronic tone) (receive function)6. Support long pre "MODE" on to shut down, short pre "MODE" on to power on, power off is very lowAll controls support serial AT commands and are very powerfulThe BK3266 is a low power, highly integrated Ble system on chip (SoC) audio device. It integrates a high performance Bluetooth-Compatible RF nsceiver, feature rich baseband proceor, F memory controller, multe og and dial peripherals, and a Bluetooth-Compatible stack including the audio, voice, and SPP profiles. The cache based architecture enables full programmability with an SIP 8M F memory device and can be used for both control and multimedia hybrid applications. The internal dual stereo ADC converts stereo og input to dial signals that can be proceed with a dial equalizer. Hardware realizations of the equalizer offload the MCU ing 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 220 mA internal battery charge controller to further reduce external bill of material (BOM) costsFeatureOperation voltage from 2.8 V to 4.2 V9 mA average current for A2DP300 uA for 500 ms sniff current0.8 uA deep sleep currentBluetooth-Compatible 4.2 claic and low energyA2DP v1.3, AVRCP v1.6, HFP v1.7, HID v1.1, AVCTP v1.4, AVDTP v1.3, and SPP v1.2True wirele stereo and two active linkTwo wires UART download interface16 bits stereo ADC and DACStereo line in and dual microphoneFive bands dial hardware equalizer, UART, I2C, SDIO and USB master and interface with MCLK outputInterface for external PA and LNAUp to 220 mA battery charge controllerApplicationsstereo speakerstereo headsetcontrol and multimedia hybrid
