nRF52833 Bluetooth® 5.1 SoC

Nordic Semiconductor's nRF52833 is an ultra-low power 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. The nRF52833 supports Bluetooth 5.1, Bluetooth mesh, 802.15.4, Thread, Zigbee^®, and proprietary 2.4 GHz protocols. It is the 5^th addition to the industry-leading nRF52^® series and includes higher-end features such as a full-speed 12 Mbps USB, high-speed 32 MHz SPI, and +8 dBm output power. The nRF52833 is built around a 64 MHz Arm^® Cortex^®-M4F and has 512 kB Flash and 128 kB RAM memory available for higher-value applications.

The nRF52833 comes with analog and digital interfaces such as NFC-A, ADC, UART/SPI/TWI, PWM, I²S, and PDM. The SoC has a 1.7 V to 5.5 V supply voltage range (two-stage LDO, one DC/DC converter), which enables powering the device from coin-cells, rechargeable batteries, or over USB. The extended temperature range of up to +105°C, a generous amount of memory, and concurrent 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 that require robust coverage.
