nRF52840 Multi-Protocol SoC

Featured Product from Digi-Key Electronics


Nordic Semiconductor's nRF52840 is an advanced multi-protocol SoC ideally suited for ultra-low power wireless applications. The nRF52840 SoC is built around a 32-bit Arm® Cortex®-M4F CPU with 1 MB Flash, and 256 kB RAM on chip. The embedded 2.4 GHz transceiver supports Bluetooth® low energy (Bluetooth 5), 802.15.4, ANT, and proprietary 2.4 GHz protocols. It is on-air compatible with existing nRF52 series, nRF51 series, and nRF24 series products from Nordic Semiconductor. The nRF52840 has hardware support on-chip for Bluetooth 5. This includes long range, high throughput, advertising extensions, and improved coexistence. It supports all Bluetooth low energy physical layer bit rates and modulation schemes.
