Brief Comparison of BLE5.1 nRF52833 and nRF52840 Parameters
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.
Nordic's new nRF52833 SoC devices will offer three different packages: 7x7 mm aQFN73 with 42 GPIOs, 5x5 mm QFN40 with 18 GPIOs, and 3.2x3.2 mm WLCSP with 42 GPIOs.
nRF52833 is an ultra-low power Bluetooth Low Energy / Bluetooth LE, Thread, ZigBee and 2.4 GHz private wireless connection solution, including Bluetooth 5.1 direction finding. 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 device radio can support all Bluetooth 5.1 direction-finding functions, and large capacity memory can be used 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 actual parameters of nRF52833 are as follows:
64 MHz ARM Cortex-M4 with FPU
512 KB Flash, 128 KB RAM
2 Mbps, 1 Mbps, Long Range
Bluetooth Low Energy
Bluetooth direction-finding

What are the advantages of nRF52833 compared with the previously released nRF52840?
The actual parameters of nRF52840 are as follows:
64 MHz ARM Cortex-M4 with FPU
1 MB Flash, 256 KB RAM
2.4 GHz Transceiver
2 Mbps, 1 Mbps, Long Range
Bluetooth 5, Bluetooth mesh
ANT, 802.15.4, Thread, ZigBee
+8 dBm TX Power
128-bit AES CCM, ARM CryptoCell
UART, SPI, TWI, PDM, I2S, QSPI
PWM
12-bit ADC
NFC-A
USB 2.0
From the specific parameters above, we know that the core of nRF52840 and nRF52833 is both M4 with floating-point operation, however, nRF52840 is twice as much as nRF52833 in RAM and Flash. The advantage of nRF52840 parameters is far greater than nRF52833. However, nRF52833 supports long range mode, which will greatly increase the communication distance. For some scenarios requiring long distance, nRF52833, the 5th generation member of Nordic’s nRF52 series, will have great advantages. Moreover, nRF52833 supports BLE 5.1 and direction-finding function, which will be a good choice for the industrial scenarios of Demand-oriented. From these points of view, nRF52840 is not as powerful as nRF52833.
