Data Breif nRF52840 (Nordic Semiconductor) - 2

High link budget for in-home applications SPECIFICATIONS The nRF52840 is the ideal solution for smart connected home ap- plications. It supports both Bluetooth 5’s long range feature and Frequency band 2.4GHz also 802.15.4 which is already a popular technology for home On-air data rate 2Mbs/1Mbs/500kbs/125kbs - Bluetooth networking protocols. With a maximum output power of 8dBm low energy a total link budget of >111dBm is achievable for achieving robust 250kbs – 802.15.4 communications through objects within the home. 2Mbs/1Mbs – 2.4GHz proprietary ARM Cryptocell 310 Output power Programmable -20dBm to +8dBm The nRF52840 features an on-chip ARM CryptoCell 310 crypto- graphic hardware accelerator. CryptoCell offers a wide range Sensitivity Bluetooth 5: -103dBm at 125kbs, -99dBm at of ciphers and security features for building solid security into 500kbs, -96dBm at 1Mbs, -92dBm at 2Mbs applications from the ground up. Use of Cryptocell also makes 802.15.4: -100dBm at 250kbs associated security operations run faster and uses less processing time and power than equivalent operation carried out in software ANT: -92.5dBm at 1Mbs by the CPU. 2.4GHz: -92.5dBm at 1Mbs, -89dBm at 2Mbs OTA DFU The nRF52840 is supported by Over-the-Air Device Firmware Radio current con- 4.8mA TX at 0dBm, DC/DC at 3V Upgrade (OTA-DFU). This allows for in the field updates of ap- sumption DC-DC 14.8mA TX at +8dBm, DC/DC at 3V plication and/or protocol stack. at 3v 9.6mA TX at +4dBm, DC/DC at 3V Nordic SoftDevices 4.6mA RX at 1Mbps Nordic protocol stacks are known as SoftDevices. SoftDevices are Microcontroller ARM Cortex-M4F pre-compiled binaries without runtime dependencies. They reside in a separate memory location to your application and offer Program memory 1MB Flash with cache safer, easier, and more secure application development. RAM 256kB The nRF52840 is supported by the S140 SoftDevice which sup- ports 20 links operating concurrently. Oscillators 32MHz crystal oscillator, 64MHz RC oscil- lator, 32kHz crystal oscillator, 32kHz RC S140 SoftDevice oscillator The S140 SoftDevice supports 20 Bluetooth LE links in concurrent System current 0.5μA at 3V System OFF mode, no RAM operation operation for all 4 roles (Central/Peripheral/Broad- caster/Ob server). The S140 is a Bluetooth 5 qualified stack and as consumption retention such supports the latest long range and high throughput features 1.5μA System ON mode, no RAM retention introduced in Bluetooth 5. 0.7μA All peripherals in IDLE mode 0.03μA per 4kB RAM retention Hardware security 128-bit AES ECB/CCM/AAR co-processor
