First,low-power Bluetooth chip smart watch solution
In order to meet the current market demand of lightweight,long battery life and high stability of smart watches,RAMSUN launched a new smart watch solution,the core of which is equipped with Zhongke Lanxun AB5690X low-power Bluetooth chip.As a high-performance SoC chip specially developed for wearable devices,this Bluetooth chip has high integration and excellent power control,which perfectly adapts to the running scene of smart watches,and can effectively solve the pain points of traditional wearable devices such as short battery life,weak computing power and poor compatibility.It is a high-quality hardware selection for mass production of smart watches.
Second,AB5690X low-power Bluetooth chip core hardware configuration
（1）Peripheral configuration of AB5690X low-power Bluetooth chip
The AB5690X low-power Bluetooth chip is equipped with a 160MHz high-performance 32-bit RISC-V processor,a DSP instruction core,a 400KB memory and a 128mbit on-chip flash memory,which is sufficient to support the daily data operation,interface display and multifunctional operation of smart watches.The chip is equipped with 38 programmable GPIO pins,which support pull-up and pull-down resistance adjustment,GPIO wake-up and interrupt triggering.With 6 timers and 6 PWM channels,it can flexibly adapt to the expansion of various peripherals and meet the development needs of personalized functions of smart watches.
（2）Rich interfaces and stable Bluetooth transmission
In terms of transmission and interface,the Bluetooth chip is fully compatible with the mainstream standards of Bluetooth 6.0,BR,EDR and BLE,with the maximum transmitting power of+10.5DBM,and the receiving sensitivity in 2M EDR mode is as low as-94.5DBM,with stable Bluetooth connection and strong anti-interference ability.At the same time,Bluetooth chip integrates full-speed USB2.0 controller,dual-channel UART interface,SD card controller and multi-mode SPI display driver,which is suitable for smart watch screen display,data transmission,peripheral connection and other full scenes.
（3）Low power battery life and wide temperature adaptation
Endurance and stability are the core considerations of smart watches.The Bluetooth chip AB5690X has a built-in high-performance PMU power management module and a 300mA lithium battery charging circuit,which supports the adaptation of multi-specification high-voltage lithium batteries,and relies on the VUSB interface to realize functions such as charging wake-up and communication reset.The chip integrates microphone amplifier,high-performance ADC,DAC,with ANS,AEC,PLC audio optimization technology,which can guarantee the high-definition call quality.The working temperature of Bluetooth chip products ranges from-40℃to+85℃,and it is packaged in a small QFN52 6×6 package,which is small in size and lower in power consumption,and fully meets the needs of smart watches for thinness and all-weather use.
