The nRF52833 is an ultra-low-power multiprotocol SoC qualified for operation
at an extended temperature range of -40° C to 105° C. Its feature set fulfills
the requirements of professional lighting, advanced wearables, and higher
value IoT applications. It supports Bluetooth LE, Bluetooth mesh, 802.15.4,
Thread, Zigbee, and proprietary 2.4 GHz protocols.
The nRF52833 is built around a 64 MHz Arm Cortex-M4 with floating-point
unit (FPU). It has 512 KB flash and 128 KB RAM memory available for highervalue applications. The extended temperature range up to 105° C, a generous
amount of memory, and dynamic multiprotocol support ensures the nRF52833
is an ideal device for a wide range of commercial and industrial applications,
including professional lighting and asset tracking. The 1:4 RAM to Flash ratio
and +8 dBm output power make the nRF52833 SoC suitable for advanced
wearables or smart home applications where robust coverage is important.
It includes a range of analog and digital interfaces such as NFC-A, ADC,
Full-speed 12 Mbps USB 2.0, High-speed 32 MHz SPI, UART/SPI/TWI, PWM,
I2S, and PDM. The 1.7 V to 5.5 V supply voltage range, enables powering the
device from rechargeable batteries or over USB.
Wireless protocol support
The nRF52833 SoC supports an extensive range of wireless protocols. It
supports Bluetooth Low Energy and is capable of all angle-of-arrival and
angle-of-departure roles in Direction Finding, Long Range, high-throughput
2 Mbps and Advertising Extensions features. Mesh protocols like Bluetooth
mesh, Thread and Zigbee can be run concurrently with Bluetooth LE, enabling
smartphones to provision, commission, configure and control mesh nodes.
NFC, ANT, 802.15.4 and 2.4 GHz proprietary protocols are also supported.

Bluetooth Direction Finding
The nRF52833 includes a radio capable of Bluetooth®
Direction Finding. Direction Finding enables
positioning solutions to not only rely on received signal
strength indicator (RSSI), but also the actual direction of a
signal. This improves accuracy and opens new possibilities
for applications in this segment. There are two types of
methods for determining direction, angle of arrival (AoA),
where the direction of the received signal is calculated,
and angle of departure (AoD), where the direction of the
transmitted signal is calculated. In addition to act as a
simple transmitter in either scheme, the generous available
memory and processing power on the nRF52833 also
allows for calculating the angles when being a receiver in
either AoA or AoD mode. Illustrated below is an example
of a real time location system (RTLS) where the principle of
AoA is used to deremine the location of a tag.
