Bluetooth SoCs feature low power consumption

The SoCs integrate a high-performance 2.4GHz radio frequency (RF) transceiver with a 32-bit ARM Cortex-M0 microcontroller, 128 kBytes of flash memory, and 64 kBytes of system memory, providing additional signal processing and room to run applications for a true single-chip Bluetooth Smart solution.

In addition to the BLE radio and microcontroller, QN902x SoCs incorporate 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 analogue-to-digital converter (ADC), two analogue comparators, and up to 31 general-purpose input/output (GPIO) pins.

The SoCs operate from a power supply range of 2.4V to 3.6V and have very low power consumption in all modes, enabling long lifetimes in battery-operated systems while maintaining excellent RF performance.

In addition, engineers can use the SoC 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 provides easy-to-access buttons, a piezo buzzer, and LEDs, allowing engineers to evaluate the onboard QN9020 SoC. The development board features a USB port for UART communications, a JLink debug interface, and a GPIO or optional sensor board connector is 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.
