Dialog Semiconductor recently announced the next generation in its SmartBond family. The DA14586 SoC is the company’s first standalone device qualified to support the latest Bluetooth 5.0 specification. It delivers the lowest power consumption and unrivaled functionality for advanced use cases.
The DA14586’s features, specs, and benefits:
- Bluetooth 5 qualified
- An integrated microphone interface allows manufacturers to add intuitive intelligent voice control to any cloud connected product that has a microphone and speaker
- Enhancements include an advanced power management setup with both buck and boost converters, which enable support of most primary cell battery types.
- Double the memory of its predecessor for user applications, making it ideal for adding Bluetooth low energy to proximity tags, beacons, connected medical devices, and smart home applications.
- Advanced features allow for mesh-based networked applications to be simply supported.
- Supported by a complete development environment and Dialog’s SmartSnippets software to help engineers optimize software for power consumption.

Nordic Semiconductor’s Bluetooth 5 developer solution for its nRF52840 SoC comprises the Nordic S140 v5.0 multi-role, concurrent protocol stack that brings Bluetooth 5’s long range and high throughput modes for immediate use to developers on the Nordic nRF52840 SoC. The Nordic nRF5 SDK offers application examples that implement this new long-range, high-throughput functionality. The existing Nordic nRF52832 SoC is also complemented with a Bluetooth 5 protocol stack.
Bluetooth 5’s high throughput mode offers not only new use cases for wearables and other applications, but also significantly improves user experience with Bluetooth products. Time on air is reduced and thus leads to faster more robust communication as well as reduced overall power consumption. In addition, with 2 Mbps, the prospect of audio over Bluetooth low energy is possible.
The new Preview Development Kit (nRF52840-PDK) is a versatile, single-board development tool for Bluetooth 5, Bluetooth low energy, ANT, 802.15.4m, and 2.4-GHz proprietary applications using the nRF52840 SoC. The kit is hardware compatible with the Arduino Uno Revision 3 standard, making it possible to use third-party-compatible shields. An NFC antenna can be connected to enable NFC tag functionality. The kit gives access to all I/O and interfaces via connectors and has four LEDs and four buttons which are user-programmable.

Nordic Semiconductor’s new Bluetooth 5-ready nRF52840 SoC is well suited for smart home, advanced wearables, and industrial IoT applications. In addition to supporting 802.15.4, it’s capable of delivering Bluetooth low energy (BLE) wireless connectivity with up to 4× the range or 2× the raw data bandwidth (2 Mbps) compared with the BLE implementation of Bluetooth 4.2
The nRF52840 SoC’s features, specs, and benefits:
- Features a 64-MHz, 32-bit ARM Cortex M4F processor employed on Nordic’s nRF52832 SoC
- A new radio architecture with on-chip PA boosting output power considerably, and extending the link budget for “whole house” applications, a doubling of flash memory to 1 MB, and a quadrupling of RAM memory to 256 KB
- Support for Bluetooth 5, 802.15.4, ANT, and proprietary 2.4-GHz wireless technologies
- A full-speed USB 2.0 controller
- A host of new peripherals (many with EasyDMA) including a quad-SPI
- Operates from power supplies above 5 V (e.g., rechargeable battery power sources)
- Incorporates the ARM CryptoCell-310 cryptographic accelerator offering best-in-class security for Cortex-M based SoCs. Extensive crypto ciphers and key generation and storage options are also available.
Nordic released the S140 SoftDevice and associated nRF5 SDK with support for Bluetooth 5 longer range and high throughput modes in December 2016. Engineering samples and development kits are now available. Production variants of the nRF52840 will be available in Q4 2017.
