nRF52833 SoC

The nRF52833 features a Bluetooth 5.1 Direction Finding-capable radio and is qualified for operation across a -40 to 105°C temperature range

The nRF52833 SoC joins Nordic’s popular nRF52 Series line-up offering an ideal option for professional lighting and other industrial applications that require a proven multiprotocol solution with high-temperature capability, direction finding, and robust coverage

Nordic Semiconductor today announces the nRF52833 advanced multiprotocol System-on-Chip (SoC), the fifth addition to its popular and proven nRF52 Series. The nRF52833 is an ultra low power Bluetooth® Low Energy (Bluetooth LE), Thread, Zigbee, and 2.4-GHz proprietary wireless connectivity solution that includes a Bluetooth 5.1 Direction Finding-capable radio and is qualified for operation across a -40 to 105°C temperature range. The nRF52833 features a powerful 64-MHz 32-bit Arm® Cortex®-M4 processor with FPU and includes a generous amount of Flash (512 KB) and RAM (128 KB) memory making it an ideal option for a wide range of commercial and industrial wireless applications including professional lighting, asset tracking, smart home products, advanced wearables, and gaming solutions. 

The SoC’s large amount of Flash and RAM memory supports a dynamic multiprotocol capability which is an advantage for applications such as professional lighting where concurrent Bluetooth LE and Bluetooth mesh/Thread/Zigbee support enables provisioning, commissioning, and interaction with a lighting mesh network from a smartphone using Bluetooth LE. The SoC’s 105°C capability brings a further advantage for professional lighting applications which typically feature elevated ambient temperatures.   

The nRF52833’s radio is capable of all Bluetooth 5.1 Direction Finding features and the large memory can support both receiver and transmitter roles for Angle-of-Arrival (AoA) and Angle-of-Departure (AoD) applications. 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).

The nRF52833 includes advanced features—including Full-Speed USB, High-Speed SPI, and +8 dBm output power—previously only available on Nordic’s flagship nRF52840 multiprotocol SoC. The increased output power together with Bluetooth 5 technology’s Long Range feature ensures the nRF52833 is an ideal choice for smart-home applications demanding robust connections and complete building coverage. The SoC includes up to 42 GPIOs and a range of analog and digital interfaces such as an NFC-A Tag, ADC,  UART/SPI/TWI, PWM, I2S, and PDM. The device has a two-stage LDO voltage regulator and a DC-DC converter with a 1.7 to 5.5-V input supply range, allowing the nRF52833 SoC to be powered by coin-cells, rechargeable batteries, or the on-chip USB.
The nRF52833 brings even more versatility to what is a very mature hardware and software platform used in hundreds of millions of products across the globe

“For Quuppa it is exciting that Nordic Semiconductor extends their portfolio with yet another SoC enhanced with Bluetooth 5.1 Direction Finding capabilities,” says Fabio Belloni, Chief Customer Officer and Co-Founder at Quuppa. “The nRF52833 SoC fits perfectly into the Quuppa Ecosystem by coupling very low power consumption with ample memory and a highly advanced radio, providing great value.”

The nRF52833 is supported by the S113 or S140 SoftDevices, Nordic’s Bluetooth RF protocol stacks. The S140 is a qualified Bluetooth 5.1 stack and includes support for 2 Mbps throughput, Bluetooth Long Range, and improved coexistence through Channel Selection Algorithm #2. The nRF5 Software Development Kit (SDK) provides all necessary examples, libraries, and drivers 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.

“Xicato provides a complete solution, both hardware and software, of Bluetooth mesh lighting controls enabling a superior range of control and monitoring for lighting systems and smart buildings, connecting tens of thousands of nodes in a single network,” says Sam Miri, Senior Vice President, Sales and Business Development at Xicato. “This requires robust and reliable Bluetooth hardware and the nRF52833, with its extended temperature range and memory to support the full Bluetooth mesh stack and application software, is a great fit for our portfolio of smart lighting and control solutions.”

The nRF52833 Development Kit (DK) accompanies the SoC’s introduction and is the ideal design tool to start nRF52833-based designs. The DK is a versatile single board development kit for Bluetooth LE, Bluetooth mesh, 802.15.4, Thread, Zigbee, and 2.4GHz proprietary applications running on the nRF52833 SoC. The DK is compatible with the Arduino Uno Rev3 standard, enabling the use of the compatible Nordic Power Profiler Kit and a wide range of third-party shields during development.

“The nRF52833 brings even more versatility to what is a very mature hardware and software platform used in hundreds of millions of products across the globe,” says Kjetil Holstad, Director of Product Management with Nordic Semiconductor. “Such stability is especially important for commercial and industrial markets where product lifetimes are generally longer.”

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.
