The Lenovo VIBE X2 Pro smartphone, due to be released in April this year, will use the LPC54100 series of MCUs from NXP Semiconductors for always-on sensor processing applications. Lenovo selected this MCU for its processing power and power efficiency to maximise battery life while supporting today's popular and innovative always-on sensor-based features.
Average smartphones use up to 12 sensors to detect or measure data such as movement, orientation, location, voice and light intensity. As an ultra-low-power sensor hub, LPC54100 MCUs offer a more power-efficient alternative to an application processor for sensor interface and processing, using as little as 3µA for always-on 'sensor listening' and as little as 55µA/MHz for active mode sensor data aggregation.
The power-efficient Cortex-M4 core provides ample bandwidth for sensor fusion algorithms to support features such as motion, gesture control and context awareness, and can scale to address new use cases or new features as they become available.
“Sensors are increasingly being used to drive innovative design of smart devices that are aware of their external environment. This ‘always listening’ nature, of course, uses more power and battery life which is a major issue for consumers,”commented Jim Trent, Vice President and General Manager, MCU Secure Monitoring & Control, NXP Semiconductors. "The LPC54100’s breakthrough power efficiency is enabling the new Lenovo VIBE to enhance the mobile user's experience with extended battery life by off-loading the application processor from taxing sensor-based features like motion, gestures, and context awareness. The MCU's performance and power scalability give our customers the flexibility to further differentiate future generations of products with additional features and use cases.”
