Nanopower announces volume production of Award Winning nPZero Power-Saving IC for battery-powered and energy harvested IoT

NUREMBERG, Germany, March 10, 2026 /PRNewswire/ -- Nanopower Semiconductor, a European fabless semiconductor manufacturer, announces that their award winning nPZero power-saving integrated circuit (PSIC) is now in volume production enabling, original equipment manufacturers (OEMs) to move from evaluation to high-volume deployment in power-constrained Internet of Things (IoT) products. Nanopower's nPZero is a power-saving integrated circuit (PSIC) designed to reduce the energy consumption of battery-powered applications by up to 90%. Samples and development kits are immediately available.

At Embedded World in Nuremberg, visitors can meet Nanopower Semiconductor at Hall 4 / Booth 4-460 to see nPZero in action and discuss design-in options and evaluation hardware. Nanopower will showcase demonstrations focused on battery-powered and energy-harvesting, helping embedded engineers extend operating life and reduce maintenance by keeping the microcontroller in deep sleep for longer periods.

Rewriting IoT power budgets: Meet nPZero

nPZero is a power-saving IC that enables always-on monitoring and control of sensors with the host microcontroller powered down. In operation, nPZero powers down the microcontroller, takes over the controller role, and autonomously handles power-up, configuration, and data reading from up to four sensors or other peripherals. The host is powered up, and control is returned when triggered by user-defined rules, allowing to remain off for long periods while the system continues to detect and respond to events.

nPZero is designed for battery-powered and energy-harvesting IoT devices where energy budgets limit sensing frequency, uptime, or maintenance intervals. Typical deployments include smart buildings, smart cities, and smart agriculture, as well as tracking, logging, and monitoring applications where devices must remain in the field for long periods and respond reliably to threshold events.

In a reference use case, nPZero has been empirically shown to significantly reduce current consumption for peripheral polling compared to a baseline system without nPZero. The measured system included a wireless microcontroller development kit plus a temperature sensor and a three-axis accelerometer.

Why energy efficiency is now a competitive advantage

Design teams building sensor-based IoT devices are under pressure to do more with less energy. In many systems, the microcontroller is woken frequently just to poll sensors, burning power even when nothing has changed. This creates a direct cost and operational burden as product fleets scale: shorter battery life, more maintenance visits, and tighter constraints on what can be measured, logged, or transmitted.

nPZero changes that system-level power profile by moving routine sensing and decision-making into an ultra-low-power companion IC, so products can remain responsive to real-world events without repeatedly waking the host processor.

To support fast evaluation and design-in, Nanopower provides access to the nPZero Configurator, which enables developers to adjust settings through a graphical user interface and automatically generate the necessary application programming interface (API) code, reducing manual bring-up effort.
