Nordic Semiconductor’s nRF52833 is an ultra-low-power Bluetooth 5.3 SoC that supports Bluetooth LE, Bluetooth mesh, NFC, ANT, Thread, Zigbee, 802.15.4, and proprietary 2.4 GHz protocols. Extended features of Bluetooth connectivity include direction finding and simultaneous operation of mesh protocols with Bluetooth LE, enabling smartphones to provision, commission, configure and control mesh nodes.
Nordic’s device is qualified for deployment at temperatures between -40°C and 105°C, making it well suited for applications that include professional lighting, advanced wearables, and higher-value IoT devices such as asset tracking and industrial IoT, as well as smart home applications and gaming; robust coverage is supported by the device’s +8 dBm output power.
The nRF52833 includes a range of analogue and digital interfaces such as NFC-A, ADC, full-speed 12 Mbps USB 2.0, and high-speed 32 MHz SPI. The device has a 1.7 V to 5.5 V supply voltage range to support powering the device from rechargeable batteries or over USB. Several power modes allow for extended battery life: For example, at 3 V input, the device consumes a mere 1.8 μA in System ON with full RAM retention.
