“The nRF52840 SoC builds on the success of the nRF52 series, but will enable wireless product developers to embark on even more ambitious single-chip smart home, wearables and IoT applications,” says Thomas Bonnerud, director of product management. “The new Bluetooth 5 long range feature makes Bluetooth a genuine contender for smart home device communication and the nRF52840 is designed to meet and exceed developer expectations. Security cannot be an afterthought in today’s connected products, the consequences can prove disastrous.”
The nRF52840 supports Bluetooth 5, shortly to be adopted by the Bluetooth SIG. This enables longer range and throughput improvements that enhance the technology’s applicability for smart home, wearables, and IoT applications. This, coupled with increased maximum output power, is said by the company to extend range by a factor of four or to double the data rate to 2Mbit/s, when compared to Bluetooth 4.2 low energy.
The device also supports IEEE 802.15.4, offering developers the ability to create ZigBee and Thread based systems. Proprietary 2.4GHz communications can also be developed.
Featuring a Cortex-M4F processor running at 64MHz, the part has 1Mbyte of flash and 256kbyte of RAM. And, with security in mind, the part offers ARM’s CryptoCell-310 cryptographic accelerator.
Bonnerud added: “With ARM CryptoCell hardware on-chip, we are equipping developers with the very best-in-class hardware and software security options to build secure products.”
