Nordic Bluetooth 5.1 SoC for 105oC ambient temperature enables wider range of concurrent multi-protocol Bluetooth low energy, mesh and Thread applications

Oslo, Norway – October 21, 2019 – Nordic semiconductor announced the nRF52833 advanced multiprotocol system-on-chip (SoC), the fifth new member of its popular and proven nRF52 family. The nRF52833 is an ultra-low power Bluetooth Low Energy (Bluetooth LE), Thread, Zigbee and 2.4 GHz private wireless connectivity solution that includes a Bluetooth 5.1 DF capable radio and can operate at -40 to 105 Effective operation in the °C temperature range. The nRF52833 is based on a 64 MHz 32-bit ArmCortex-M4 processor with FPU, and due to its large flash (512 KB) and RAM (128 KB) memory, it is ideal for applications including professional lighting, asset tracking, smart home products, advanced wearables Various commercial and industrial wireless applications including devices and gaming solutions.

The large-capacity flash memory and RAM memory of the nRF52833 SoC can support dynamic multi-protocol functions, which is an advantage in applications such as professional lighting. When the application can concurrently support Bluetooth low energy and Bluetooth mesh/Thread/Zigbee functions, their configuration, Commissioning as well as interacting with the lighting mesh network can be done from a smartphone using Bluetooth Low Energy. The 105°C operating performance of this SoC device provides a further advantage in professional lighting applications that typically require higher ambient temperatures.

The nRF52833 device radio can support all Bluetooth 5.1 direction finding functions, and the large memory can support both receiver and transmitter in Angle of Arrival (AoA) and Angle of Departure (AoD) applications. The direction finding function enables positioning applications to rely not only on the received signal strength indication (RSSI), but also on the signal direction. Typical applications include real-time positioning systems (RTLS) and indoor positioning systems (IPS).

The nRF52833 device features leading-edge features including full-speed USB, high-speed SPI and +8dBm output power previously only available on Nordic’s flagship nRF52840 multi-protocol SoC. The combination of higher output power and the long-range capabilities of Bluetooth 5 technology ensures that the nRF52833 is ideal for smart home applications that require robust connectivity and full building coverage. This SoC device includes up to 42 GPIOs and a range of analog and digital interfaces such as NFC-A tags, ADC, UART/SPI/TWI, PWM, I2S and PDM interfaces. The device features a two-stage LDO regulator and a DC-DC converter with an input supply range of 1.7-5.5 V, allowing the nRF52833 SoC to be powered by a coin cell, rechargeable battery, or on-chip USB.

Fabio Belloni, Chief Customer Officer and Co-Founder of Quuppa, said: “We are very excited to add an enhanced SoC device with Bluetooth 5.1 direction finding to the Nordic Semiconductor product family. The nRF52833 SoC combines extremely low power consumption with ample memory And a very cutting edge radio that offers great value, perfectly integrated into the Quuppa ecosystem.”

The nRF52833 is supported by the Nordic Bluetooth RF stack S113 or S140. The S140 is a qualified Bluetooth 5.1 stack that supports 2 Mbps throughput, Bluetooth long range, and better compatibility through channel selection algorithm #2. The nRF5 Software Development Kit (SDK) provides all the examples, libraries and drivers needed to get started with Bluetooth Low Energy development. Nordic plans to release nRF5 SDKs for Mesh and Thread and Zigbee applications in Q4 2019.

“Xicato provides complete Bluetooth mesh lighting control solutions including hardware and software,” said Sam Miri, senior vice president of sales and business development at Xicato. “These solutions enable lighting systems and smart buildings by connecting tens of thousands of nodes in a single network. Large control and monitoring range. This requires robust and reliable Bluetooth hardware and the nRF52833 device, whose extended temperature range and memory support the full Bluetooth mesh stack and application software, is a perfect fit for our portfolio of smart lighting and control solutions.”

The nRF52833 Development Kit (DK), available with the SoC device, is the ideal design tool to start designing based on the nRF52833. This versatile single-board development kit is suitable for Bluetooth Low Energy, Bluetooth mesh, 802.15.4, Thread, Zigbee and 2.4GHz proprietary applications running on the nRF52833 SoC. Compatible with the Arduino Uno Rev3 standard, this development kit can use a compatible Nordic Power Profiler kit and a variety of third-party modules during development.

Kjetil Holstad, Director of Product Management at Nordic Semiconductor, said: “The nRF52833 brings additional functionality to the very mature hardware and software platforms used in hundreds of millions of products worldwide, and this stability is especially useful in commercial and industrial markets where product life is typically long. important.”

Nordic is now offering engineering samples of the nRF52833, with mass production expected in the fourth quarter of 2019. The SoC device will be available in three different packages: a 7×7 mm aQFN73 with 42 GPIOs, a 5×5 mm QFN40 with 18 GPIOs, and a 3.2×3.2 mm wlCSP package with 42 GPIOs.
