　　The LPC54100 Series microcontrollers were designed from the ground up to deliver the industry’s best power efficiency for always-on sensor-processing applications. These highly efficient MCUs support ultra-low-power performance for sensor tasks such as listening， collection， and aggregation of sensor data as well as complex sensor processing tasks such as sensor fusion.

　　Crucial for always-on applications， LPC54100 Series MCUs require as little as 3 μA for continuous sensor listening. A first for sensor applications， an asymmetric dual-core architecture enables scalable active power/performance： Developers can use the 55 μA/MHz Cortex-M0+ core for sensor data collection， aggregation， and external communications， or the Cortex-M4F core （100 μA/MHz） to execute math-intensive algorithms （i.e.， motion sensor fusion） more quickly while saving power. The LPC54100 Series also includes single-core （Cortex-M4F） options with similar sensor listening and M4F power efficiencies.
