Low-power Bluetooth SoCs, the QN902x series, and the QN9020 Bluetooth development kit, by NXP Semiconductors, are available from Mouser Electronics. The integrated, ultra-low-power Bluetooth v4.0 Low Energy (BLE) SoCs can be used for Bluetooth Smart applications such as sports and fitness wearables, human interface devices, and app-enabled smart accessories. They integrate a high-performance 2.4GHz RF transceiver with a 32bit ARM Cortex-M0 microcontroller, 128kbytes of flash memory, and 64kbytes of system memory. In addition to the BLE radio and microcontroller, the SoCs incorporate the BLE protocol stack and profile software on a single chip.

There is a four-channel, 10bit ADC, two analogue comparators, and up to 31 GPIO pins. The SoCs operate from 2.4 to 3.6V supply and have very low power consumption in all modes, to extend battery operation, while maintaining RF performance. An SoC can also be used as a network processor to add Bluetooth Smart connectivity to almost any product by connecting the SoC to an application processor via UART or SPI. The NXP QN9020 Bluetooth development kit with easy-to-access buttons, a piezo buzzer, and LEDs, allows engineers to evaluate the onboard QN9020 SoC. A USB port for UART communications, a JLink debug interface, and a GPIO or optional sensor board connector are also included. The kit includes USB Bluetooth dongle, which works with the board as a pair for evaluation and debugging, and a USB cable for power and data transfer.
