The nRF52840 is an advanced multi-protocol system-on-chip (SoC) that supports several protocols, including the recently released Bluetooth 5 specification and is ideal for smart home, wearables, and Internet of Things (IoT) applications. The nRF52840 SoC employs a 64 MHz, 32-bit ARM Cortex-M4F processor employed on Nordic’s nRF52832 SoC, plus a CPU with ample generic processing power, floating point, and digital signal processor (DSP) performance. The embedded 2.4 GHz transceiver supports Bluetooth low energy (Bluetooth 5), 802.15.4, ANT and proprietary 2.4 GHz protocols. It includes IEEE 802.15.4 capabilities for ZigBee and Thread-based smart home technologies or as a Network Adaptation Layer with 6LoWPAN and standard internet protocols. 

The SoC supports BLE connectivity with up to four times the range or up to twice the raw data bandwidth (2 Mbps) compared to the Bluetooth low energy implementation of Bluetooth 4.2. It has NFC-A tag support on the chip. NFC Type 2 and Type 4 tag emulation protocol stacks are provided for new applications, like NFC payment and Out-of-Band (OOB) pairing. OOB pairing using NFC simplifies the process of authenticated pairing between two Bluetooth devices by exchanging authentication information over an NFC link. It has on-chip USB 2.0 (Full speed) support and on-chip VBUS regulation allowing for direct connection to USB hosts for data transfer and direct USB power for hosted applications.

The nRF52840 is available in 7 x 7 mm 73 pin AQFN package with 48 available GPIO. Nordic provides protocol stacks for Bluetooth low energy. ANT protocol stacks are available from ANT.
