In summary, NXP’s LPC54100 Series microcontrollers were designed from the ground up to deliver 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. You 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. 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. Together these features enable LPC54100 series MCUs to offer the overall power efficiency for sensor processing than any other microcontrollers in this class.
