Brief Parameter Comparisons between BLE5.1 nRF52833 and BLE5.0 nRF52840

As the fifth new member of the 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 aQFNTM73 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 a 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 the 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 the signal direction. Typical applications include the 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
• Bluetooth mesh
• Thread, ZigBee
• +8 dBm TX Power
• 128-bit AES CCM
• UART, SPI, TWI, PDM
• HS-SPI, I2S, PWM
• 12-bit ADC
• NFC
• USB 2.0

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

What are the advantages of nRF52833 compared with the previously released nRF52840?

From the specific parameters above, we know that the core of nRF52840 and nRF52833 is both M4 with the 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. nRF52833 supports BLE 5.1 and direction-finding function, which will be a good choice for the industrial scenarios of Demand-oriented. In some points of view, nRF52840 is not as powerful as nRF52833.

RF-star Technology previously launched the RF-BM-ND05 and RF-BM-ND06 module with excellent performance using the nRF52840 chip.
