Bluetooth 5.1 SoC DA14531 for electronic price tags application

- Oct 17, 2020-

In November 2019, Dialog Semiconductor launched Bluetooth 5.1 SoC SmartBond TINY™ DA14531 with the smallest size and the highest power efficiency in the world, when working at 0dBm, it’s TX and RX consumption are 3.5mA and 2.2mA specifically, which means even utilize a coin cell battery, the battery life can be up to years.


With the development of the Internet of Things or smart devices, more and more devices need wireless connection. However, not all devices need to transmit large data, nor do they necessarily need a lot of power. At this time, Bluetooth connection seems to be a better way. In addition, if you want to have a connection with a mobile device in an existing product to facilitate the use of the application, and provide a simple setting or operation interface, if the existing product is added with the connection function at a lower cost, it is more than a complete refurbishment. The design is easier.


DA14531 can be used in smart medical care, especially in many wearable devices.
