Bluetooth Low Energy (Bluetooth LE)

Broad portfolio of Bluetooth Low Energy SoCs

Want to add Bluetooth Low Energy connectivity to your product?

If you want to add Bluetooth Low Energy connectivity to your product, you have come to right place. We offer a broad portfolio of wireless multiprotocol System-on-Chips (SoCs). All our SoCs are extremely advanced and power efficient, but have different feature sets and memory configurations. We ship more than 1 million Bluetooth LE SoCs every day and in 2022 alone our customers certified 446 new end-products, making us the market leader (39 % market share). Our customers select us because we offer high quality SoCs with ultra-low power consumption, protocol stacks with excellent interoperability and easy-to-use software and tools. In addition, we offer free technical support for anyone, guiding you through the whole product development process. Explore our Bluetooth Low Energy solutions below!

Best-in-class Bluetooth Low Energy SoCs

Bluetooth Low Energy flagship SoC

The nRF5340 SoC is our Bluetooth Low Energy flagship. It is the first SoC in the nRF53 Series and is the world’s first wireless SoC with two Arm® Cortex®-M33 processors. The combination of two flexible processors and the advanced feature set make it the ideal choice for LE Audio, advanced wearables, and other complex IoT applications. The nRF5340 is an all-in-one SoC, including a superset of the most prominent nRF52® Series features. Features like Bluetooth® 5.4, high-speed SPI, QSPI, USB, up to 105 °C operating temperature, and more, are combined with more performance, memory and integration, while minimizing current consumption. It also offers security features such as trusted execution, root-of-trust and secure key storage.

Supports an extensive range of wireless protocols

The nRF5340 is a Bluetooth 5.4 SoC and is capable of taking all angle-of-arrival (AoA) and angle-of-departure roles (AoD) in Bluetooth Direction Finding. It also supports LE Audio, Long Range, high-throughput 2 Mbps and Advertising Extensions features. Mesh protocols like Bluetooth mesh, Thread and Zigbee can be run concurrently with Bluetooth Low Energy, enabling smartphones to provision, commission, configure and control mesh nodes. NFC, ANT, 802.15.4 and 2.4 GHz proprietary protocols are also supported.

nRF52 Series

The nRF52 Series consists of seven multiprotocol Bluetooth 5.4 SoCs that integrate a powerful yet efficient 64 MHz Arm Cortex-M4 CPU. Flash memory range from 192 KB to 1024 KB while RAM range from 24 KB to 256 KB. The nRF52 Series offers simpler cost-effective options and highly-advanced options, all with ultra-low power consumption. The nRF52 Series is truly the ideal platform for basing a product portfolio upon. The similar hardware and software architecture results in excellent software portability, increasing software reusability and lowering time-to-market and development cost.

All-flash based SoCs

The nRF52 and nRF53 Series are all-flash based SoCs. Flash memory brings complete flexibility and upgradability to your products. They can be re-programmed in the factory or in the field with over-the-air device firmware upgrades (OTA DFU). This enables product updates and feature additions any time, anywhere.
