The QN902x SoCs are highly integrated, ultra-low-power, high-performance Bluetooth Low Energy v4.0 solutions for smart Bluetooth applications such as sports and fitness wearables, human interface devices, and smart accessories with enabled applications.
        
Available from Mouser Electronics, the NXP QN902x SoCs integrate a high-performance 2.4 GHz RF transceiver with a 32-bit ARM® Cortex®-M0 microcontroller, 128 KB of flash memory, and 64 KB of system memory, providing additional signal processing and space to run applications for a true smart Bluetooth single-chip solution. In addition to the BLE radio and microcontroller, the QN902x SoC incorporates the BLE protocol stack and profile software on a single chip, providing a flexible and easy-to-use BLE SoC solution. The SoCs include a four-channel, 10-bit analog-to-digital converter (ADC), two analog comparators, and up to 31 general-purpose input/output (GPIO) pins. The QN902x SoC operates from a 2.4V to 3.6V supply range and has very low power consumption in all modes, enabling long battery life for systems while maintaining excellent RF performance. Additionally, engineers can use the QN902x as a network processor to add smart Bluetooth connectivity to almost any product by connecting the SoC to an application processor via UART or SPI.
        
NXP's QN9020 Bluetooth Development Kit provides easily accessible buttons, a piezo buzzer, and LEDs, allowing engineers to evaluate the integrated QN9020 SoC. The development board features a USB port for UART communication, a JLink debugging interface, and a GPIO or optical sensor connector. The kit also includes a USB adapter for Bluetooth, which works with the board as a pair for evaluation and debugging, and a USB cable for power and data transfer.
