Datasheet Nordic Semiconductor nRF52840 — Datenblatt

nRF52840 High-end multiprotocol Bluetooth 5 SoC
Supporting: Bluetooth 5/Bluetooth mesh/Thread/802.15.4/ANT/2.4GHz Ready for Bluetooth 5 and high grade IoT security
The nRF52840 is an advanced, highly flexible single chip solution
for today's increasingly demanding ULP wireless applications for
connected devices on our person, connected living environments
and the IoT at large. It is designed ready for the major feature
advancements of Bluetooth® 5 and takes advantage of Bluetooth
5's increased performance capabilities which include long range
and high throughput modes. Inherent industry-grade security is
essential in today's applications. The nRF52840 adds best-inclass security for CortexTM-M Series with on-chip ARM® CryptoCell
cryptographic accelerator.
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-M4F processor allowing quicker and more efficient
computation of complex functions for DSP and those requiring
floating point math. There is extensive memory availability in
both flash and RAM, 1MB/256kB respectively. The combination
of Cortex-M4F and memory availability offers unparalleled capabilities for true single chip applications.
A full-speed (12Mbs) 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
(32MHz) and quad SPI (32MHz) to allow direct interfacing to displays and external memory sources. The nRF52840 can operate …
