The Power of Integrating Bluetooth Low Energy Into SoCs White Paper
The Bluetooth Low Energy (BLE) specification, released in 2011, enables designers of System-on-Chips (SoCs) to maximize the battery life of IoT devices and minimize the implementation costs of wireless sensors and other “connected things” by maximizing sleep time and simplifying Radio operation.
Because it is built on the established ecosystem of Bluetooth Classic for mobile phones and PCs, BLE is receiving wide acceptance and adoption, catapulting the Internet-of-Things (IoT) into the wide consumer market. It has quickly evolved, adding more and more features and capabilities, such as extended range, location and positioning, and mesh networking, to secure a strong hold on the IoT market and accelerate its growth.
To drive such fast growth, SoC designers must be able to integrate the BLE Radio into their SoCs with ease while focusing on their core competencies. Since extended battery life and robust wireless connection are key criteria, designers must choose the IP vendor that delivers the lowest power and highest performance solution. There are obvious trade-offs between consumption and circuit performance, and because of the complex dynamic of Bluetooth connections, it is difficult to estimate the effective duty-cycle on the consumption profiles.
This white paper explains the architectural and design aspects of successful BLE integration into SoCs, and presents how power consumption is properly measured in different representative scenarios.
