nRF52840 multiprotocol SoC is the company’s most advanced ultra low
power wireless solution. The SoC supports complex Bluetooth LE and other
wireless applications that were previously not possible with a
single-chip solution. The nRF52840 is Bluetooth 5-, Thread 1.1-, and
Zigbee PRO (R21) and Green Power proxy specification-certified. The SoC
combines a 64MHz, 32-bit Arm® Cortex® M4F processor with a 2.4GHz
multiprotocol radio (supporting concurrent wireless connectivity of
Bluetooth 5 and Thread or Zigbee, in addition to ANT™, IEEE 802.15.4,
and proprietary 2.4GHz RF protocol software). The SoC has 1MB Flash
memory and 256kB RAM. An on-chip PA features -95dBm RX sensitivity (at
1Mbps Bluetooth LE), a maximum output power of 8dBm, and a total link
budget of 103dBm. The chip supports all the features of Bluetooth 5
(including 4x the range or 2x the raw data bandwidth (2Mbps)) compared
with Bluetooth 4.2.
The SoC is supplied with Nordic’s S140 SoftDevice, a Bluetooth 5-certified software protocol stack for building long range and high data Bluetooth LE applications. The S140 SoftDevice offers concurrent Central, Peripheral, Broadcaster, and Observer Bluetooth LE roles, and supports high throughput and long range modes as well as advertising extensions. OpenThread and Zigbee stacks are available through Nordic’s nRF5 SDK for Thread and Zigbee.
“The nRF52840’s launch followed an extensive design and development process by the company’s engineering team and builds on Nordic’s many years of Bluetooth LE and low power wireless hardware and software expertise,” says Geir Langeland, Nordic’s Director of Sales & Marketing. “We are proud that those efforts have been appreciated by the nRF52840’s recognition as a winning solution in the highly competitive RF sector from the editors of a leading U.S. electronic design title.
