feature to any product. QN902x has built-in analog and digital interfaces. It enables easy connection to any analog or digital peripheral, sensor, and external application processor in network processor mode. 2. General description QN902x is an ultra low power, high performance and highly integrated Bluetooth LE solution. It is used in Bluetooth Smart applications such as sports and fitness, human interface devices, and app-enabled smart accessories. It is specially designed for wearable electronics and can run on a small capacity battery such as a coin cell battery. QN902x integrates a Bluetooth LE radio, controller, protocol stack and profile software on a single chip, providing a flexible and easy to use Bluetooth LE So C solution. It also has a high performance MCU and an on-chip memory that can support users to develop a single-chip wireless MCU solution. Users can also utilize QN902x as a network processor by connecting to an application processor for more advanced applications. Additional system features include fully integrated DC-to-DC converter and LDO, low-power sleep timer, battery monitor, general-purpose ADC, and GPIOs. These features reduce overall system cost and size. QN902x has very low power consumption in all modes. It enables long life in battery-operated systems while maintaining excellent RF performance. QN9020/1 operates with a power supply range of 2.4 V to 3.6 V. The QN9022 operates with a power supply range of 1.8 V to 3.6 V. 3.
