- Security – ARM Cryptocell CC310 cryptographic accelerator, 128 bit AES/ECB/CCM/AAR coprocessor
- Power Supply – 1.7 V to 5.5 V; individual power management for all peripherals; regulated supply for external components up to 25 mA
nRF52840 is “on-air-compatible with nRF51, nRF24L and nRF24AP Series”, and target advanced wearables, IoT, and interactive entertainment devices (remote controls / controllers).
The company has also launched nRF52840 Preview Development Kit to get started with evaluation and development. The development board is hardware compatible with Arduino Uno Rev. 3 to allow the use of common Arduino shields, and also includes 4 LEDs and 4 buttons, all programmable by the user. It supports Bluetooth 5, Bluetooth low energy, ANT, 802.15.4 and 2.4GHz proprietary using the latest S140 SoftDevice software stack, as well as NFC thanks to an external antenna included in the kit. The kit is compatible with Nordic Software Development Toolchain using Keil, IAR and GCC, and can be programmed & debugging with Segger J-Link OB.
Samples and the development kit are available now at an undisclosed price. You’ll find more details about the nRF52840 Bluetooth 5 SoC and development kit on the product page.
