nRF52833 - Bluetooth 5.1 SoC for BLE, Mesh and Thread Applications

Nordic Semiconductors announces the nRF52833, advanced multi-protocol System on chip (SoC) as the fifth addition to its nRF52 series.  The nRF52833 is an ultra low power Bluetooth module that can be used in Bluetooth Low Energy (BLE), Thread, Zigbee and 2.4GHz wireless connectivity solutions. The SoC's large amount of flash and RAM memory supports a dynamic multi-protocol capability, it is an advantage for professional lighting applications where concurrent Bluetooth and Bluetooth mesh/Thread/ Zigbee support is used for provisioning, commissioning and interacting with a lighting mesh network from a Smartphone using Bluetooth LE.

The nRF52833’s radio is capable of all Bluetooth 5.1 direction-finding features and supports both receiver and transmitter roles for Angel-of-Arrival ( AoA) and Angle-of-Departure (AoD) applications with its large memory. Direction Finding enables positioning applications that not only rely on received signal strength indication (RSSI) but also the signal direction. Applications include real-time location systems (RTLS) and indoor positioning systems (IPS).

Note: For more technical details and specifications use the datasheet linked at the bottom of this page.

The nRF52833’s 105 °C capability is an advantage for professional lighting applications which typically feature elevated ambient temperatures. The SoC is ideal for applications such as asset tracking, way finding, Multiprotocol devices, Mesh networks, Advanced Wearable, Smart homes, HID/Gaming/ VR, Toys and Sport & Fitness devices.

The nRF52833 is supported by the S113 or S140 Soft Devices, Nordic’s Bluetooth RF protocol stacks. The S140 is qualified Bluetooth 5.1 stack and includes support for 2Mbps throughput, Bluetooth Long Range and Improved coexistence through a channel selection algorithm. The nRF5 Software Development Kit (SDK) has all the necessary examples, libraries and to get started with Bluetooth LE development.  The nRF5 SDK for Mesh and nRF5 SDK for Thread and Zigbee are scheduled for release in Q4 2019.

nRF52833 engineering samples are available now with volume production Q4, 2019. The SoC will be made available in three different packages: a 7x7 mm aQFN73 with 42 GPIOs, a 5x5 mm QFN40 with 18 GPIOs and a 3.2x3.2 mm wlCSP with 42 GPIOs.
