Nordic Semiconductor, an Oslo-based fabless semiconductor company, announced 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, reports Nordic.

“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.”

The SoC’s memory capacity also supports a dynamic multi-protocol capability, suitable for applications such as professional lighting where concurrent Bluetooth Low Energy and Bluetooth mesh, Thread or Zigbee support enables provisioning, commissioning, and interaction with a lighting mesh network from a smartphone using Bluetooth Low Energy. The temperature range also enables the nRF52833 to operate in professional lighting applications which typically feature elevated ambient temperatures, says Nordic.

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 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 SoC will be made available in three packages: a 7.0 x 7.0mm aQFN73 with 42 GPIOs, a 5.0 x 5.0mm QFN40 with 18 GPIOs and a 3.2 x 3.2mm wlCSP with 42 GPIOs.

The nRF52833 engineering samples are available now with volume production due Q4, 2019.
