With the rapid development of wireless audio equipment,a Bluetooth chip with high performance and low power consumption is the core to determine the competitiveness of products.BT8972H Bluetooth chip launched by Zhongke Lanxun is becoming the first choice of many audio equipment manufacturers with its excellent processing power,stable wireless connection and excellent sound quality performance.
The core of BT8972H is a high-performance 32-bit RISC-V processor,with a typical frequency of up to 140MHz and an integrated floating-point arithmetic unit(FPU),which can efficiently handle complex audio algorithms and tasks.Its 16Mb flash memory and 408KB RAM provide ample space for program running and data exchange.
The GPIO pin design of Bluetooth chip BT8972H is very flexible,supports programmable pull-up and pull-down resistors,and can be configured as a wake-up or interrupt source,which greatly facilitates the connection of external devices and the management of system power consumption,and provides more customization possibilities for product design.
In terms of wireless connection,BT8972H strictly follows the Bluetooth 6.0 standard,and is compatible with both classic Bluetooth(BR/EDR)and low-power Bluetooth(BLE)modes.It especially optimizes TWS(True Wireless Stereo)communication mechanism,which not only supports stable low-delay transmission between ears,but also realizes seamless switching between master and slave roles,thus improving the use experience of TWS headphones.
Bluetooth chip BT8972H has excellent RF performance:the highest transmission power is 12dBm(BR mode),while the receiving sensitivity is as low as-99dBm in BLE 1M mode.The high-performance stereo DAC integrated with BT8972H Bluetooth chip has a signal-to-noise ratio(SNR)of up to 122 dB(when DRE is turned on),and supports a wide range of sampling rates from 8kHz to 192kHz,which can accurately restore sound details and present a clear and pure listening experience.
In addition,Bluetooth chip BT8972H also integrates three high-performance ADCs,with a signal-to-noise ratio of 105dB and a sampling rate of up to 384kHz.It can support three-channel single-ended or differential microphone input,and combined with flexible audio equalizer adjustment function,it can not only achieve high-definition call noise reduction,but also provide a hardware foundation for different styles of sound adjustment.
In terms of size,BT8972H Bluetooth chip adopts QFN32 4mm x 4mm compact package,which integrates rich functions in a very small area and is helpful to develop smaller and lighter terminal products.The working temperature range of Bluetooth chip BT8972H is-40 C to+85 C,and the storage temperature range is wider,which ensures the high reliability and long life of the chip in various harsh environments and meets the needs of consumer electronics and some industrial applications.
