Advantages Comparison between Long Range nRF52833 and nRF52832 Sep 15, 2021

As the fifth new member of Nordic nRF52 series, nRF52833 SoC can provide multi-protocol solutions that support high temperature performance (up to 105 ℃) and direction finding function. And it quickly becoming one of the best choices for professional lighting and other industrial applications.


nRF52833 is an ultra-low power Bluetooth® Low Energy / Bluetooth LE, Thread, ZigBee and 2.4 GHz private wireless connection solution, which contains Bluetooth 5.1 with direction-finding function, and it can operate effectively in the temperature range of -40 ° C to 105 ° C.


nRF52833 uses 64 MHz 32-bit Arm® Cortex®-M4 processor with FPU. It contains large capacity Flash (512 KB) and RAM (128 KB), so it is very suitable for a variety of commercial and industrial wireless applications, including professional lighting, asset tracking, smart home products, advanced wearable devices and game solutions.

nRF52833 can support all Bluetooth 5.1 direction-finding functions, and its large capacity memory can support it works as both receiver and transmitter in angle of arrival (AoA) and angle of departure (AoD) applications. The direction finding function makes the positioning application not only dependent on received signal strength indication (RSSI), but also on the signal direction. Typical applications include real-time positioning system (RTLS) and indoor positioning system (IPS).


The parameters of nRF52833 are as follows:


l  64 MHz Arm Cortex-M4 with FPU
l  512 KB Flash, 128 KB RAM
l  2 Mbps, 1 Mbps, Long Range
l  Bluetooth Low Energy
l  Bluetooth Direction Finding
l  Bluetooth mesh
l  Thread, Zigbee
l  +8 dBm TX Power
l  128-bit AES CCM
l  UART, SPI, TWI, PDM
l  HS-SPI, I2S, PWM
l  12-bit ADC
l  NFC
l  USB 2.0


What are the advantages of nRF52833 compared with nRF52832?


The parameters of nRF52832 are as follows:


l  64 MHz Cortex-M4 with FPU

l  512/256 KB Flash, 64/32 KB RAM
l  2.4 GHz Transceiver
l  2 Mbps, 1 Mbps
l  Bluetooth Low Energy
l  Bluetooth mesh
l  +4 dBm TX power
l  128-bit AES
l  UART, SPI, TWI, PDM, I2S
l  PWM
l  12-bit ADC
l  NFC-A

From the specific parameters above, we know that the core of nRF52832 and the nRF52833 is both M4 with floating-point operations, however, nRF52833's RAM is doubled than nRF52832. And nRF52833 supports long distance, which will greatly increase the communication distance. For some scenarios requiring long distance, nRF52833, the 5th generation member of Nordic’s nRF52 series, will be very advantageous. Moreover, nRF52833 supports BLE 5.1 and direction finding function, which will be a good choice for the industrial scenarios with direction finding function.


RF-star Technology previously launched the RF-BM-ND04 module with excellent performance using the nRF52832 chip.


nRF52833 brings more functions to the very mature hardware and software platforms used in hundreds of millions of products around the world. This stability is particularly important for commercial and industrial markets where product life is usually longer.


RF-star Technology is a well-known and reputable wireless RF solution provider and low-power RF core device supplier.
