nRF52840
High-end multiprotocol Bluetooth Low Energy (LE) SoC
supporting: Bluetooth 5.3/Bluetooth mesh/Thread/
Zigbee/802.15.4/ANT
Advanced performance, lowest power consumption
The nRF52840 employs the same hardware and software architecture as
existing nRF52 Series SoCs. At its core is an Arm Cortex-M4 processor
allowing quicker and more ecient computation of complex functions for DSP
and those requiring oating point math. There is extensive memory
availability in both ash and RAM, 1 MB and 256 KB respectively. The
combination of Cortex-M4 with oating point and memory availability oers
unparalleled capabilities for true single chip applications. A full-speed (12
Mbps) USB 2.0 controller is included on-chip. An extensive range of
peripherals are available with a number of high performance digital
interfaces such as high speed SPI (32 MHz) and quad SPI (32 MHz) to allow
direct interfacing to displays and external memory sources. The nRF52840
can operate from +5.5 V down to 1.7 V supply voltages allowing direct supply
from rechargeable batteries and USB supplies.

Thread certied and 802.15.4 support
The nRF52840 is a Thread certied component and as such
is ideal for home networking products using the Thread
mesh stack. This means it is suitable for developing products
for the Matter connected home ecosystem. The radio
supports 802.15.4 PHY and MAC layers and makes it suitable
for additional stacks using 802.15.4 such as Zigbee.
Arm CryptoCell 310
The nRF52840 features an on-chip Arm CryptoCell 310
cryptographic hardware accelerator. CryptoCell oers a
wide range of ciphers and security features for building solid
security into applications from the ground up. Use of
CryptoCell also makes associated security operations run
faster and uses less processing time and power than
equivalent operation carried out in software by the CPU.
nRF Connect SDK
The nRF Connect SDK is the software development kit for
the nRF52 Series SoCs. It supports development of Bluetooth
Low Energy, Thread and Zigbee applications. It integrates
the Zephyr RTOS, protocol stacks, samples, hardware drivers
and much more.
nRF Connect SDK also oers integration of HomeKit
Accessory Development Kit for developing products using
HomeKit.
nRF52840 Development Kit (DK)
The nRF52840 DK is the development kit for the nRF52840
SoC. It is aordable, and has everything needed for
development on a single board. All features and GPIOs of
the nRF52840 SoC are made available to the developer, and
it comes with an onboard SEGGER J-Link debugger enabling
both programming and debugging of the nRF52840 SoC,
without additional hardware investments.
The nRF52840 SoC and the nRF52840 DK is available
through Nordic Semiconductors distribution network.
