LPC54100 microcontrollers 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. They require as little as 3 µA for continuous sensor listening. 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. This architecture is complemented by a range of analog and digital interfaces designed for power efficiency — including a 12-bit, 4.8 Msps ADC capable of full-spec performance at the full voltage range, as well as low-power serial interfaces.
