Bluetooth 5.1 SoC covers -40 to 105ºC operation
The chip includes a Bluetooth 5.1 Direction Finding-capable radio and is qualified for operation across a -40 to 105ºC temperature range. The nRF52833 features a 64-MHz 32-bit Arm Cortex-M4 processor with FPU and includes a generous amount of Flash (512 KB) and RAM (128 KB) memory making it a suitable option for a wide range of commercial and industrial wireless applications.
The SoC’s large amount of Flash and RAM memory supports a dynamic multiprotocol capability which is an advantage for applications such as professional lighting where concurrent Bluetooth LE and Bluetooth mesh/Thread/Zigbee support enables provisioning, commissioning, and interaction with a lighting mesh network from a smartphone using Bluetooth LE. The SoC’s 105oC capability brings a further advantage for professional lighting applications which typically feature elevated ambient temperatures. Advanced features include Full-Speed USB, High-Speed SPI, and +8dBm output power. The SoC includes up to 42 GPIOs and a range of analog and digital interfaces such as an NFC-A Tag, ADC, UART/SPI/TWI, PWM, I2S, and PDM. The device has a two-stage LDO voltage regulator and a DC-DC converter with a 1.7 to 5.5-V input supply range, allowing the nRF52833 SoC to be powered by coin-cells, rechargeable batteries, or the on-chip USB.
nRF52833 engineering samples are available now with volume production Q4, 2019. The SoC will be made available in three different packages: a 7- x 7-mm aQFN73 with 42 GPIOs, a 5x5mm QFN40 with 18 GPIOs and a 3.2- x 3.2-mm wlCSP with 42 GPIOs.
