Overview

The ultra-low power nRF52833 is a multiprotocol SoC with a

Bluetooth 5.1 Direction Finding capable radio, qualified for

operation at an extended temperature range of -40°C to

105°C. It supports Bluetooth 5.1, Bluetooth mesh, 802.15.4,

Thread, Zigbee, and proprietary 2.4 GHz protocols.

The nRF52833 is the 5th addition to the industry leading

nRF52 Series SoC family and is built around a 64 MHz Arm

Cortex-M4 with FPU, and has 512 KB flash and 128 KB RAM

memory available for higher value 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.

A 1:4 RAM to Flash ratio and +8 dBm output power make the

nRF52833 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, and has a 1.7 V to

5.5 V supply voltage range, which enables powering the device

from rechargeable batteries or over USB. The two-stage LDO

regulator and a DC-DC converter, together with the automated

power management system help deliver low power numbers

even in more advanced applications.

Professional lighting

Saving electricity while ensuring properly lighted areas is a high

priority concern for commercial building owners. In addition to

leveraging the maturity of the tried and tested nRF52 series,

the nRF52833 comes qualified for 105°C ambient temperature

operation, and ample available memory allows for concurrent

operation of multiple protocols in the 2.4 GHz frequency band,

for instance Bluetooth Low Energy in conjunction with

Bluetooth Mesh, Thread, or Zigbee. The nRF52833 is a high

quality device targeting the performance, connectivity and

stability that is required of such systems.
