Nanopowersemi

Nanopower Semiconductor AS is a Norwegian semiconductor company that designs ultra-low-power integrated circuits intended to reduce the energy consumption of battery-powered electronic systems. Its product line is the nPZero power saving IC (PSIC) platform, which acts as a companion device alongside a host microcontroller: the PSIC handles sensor monitoring, timing and event detection at nanoampere-level current while the main processor stays powered down until an event warrants processing. The company positions the technology as compatible with a range of wireless standards and sensors, and frames the value proposition around longer battery life, fewer and smaller batteries, and reduced battery waste in large-scale industrial IoT deployments.

The current catalogue includes the nPZG1S, positioned for minimum power draw and simple ultra-low-power duty cycles, and the nPZ2100, positioned for feature-rich smart IoT devices requiring more control and an industrial temperature range. The nPZ2100, announced in August 2026, has typical idle consumption of 200nA at 3.0V and 1µA polling consumption, can autonomously manage up to six independent peripherals over I²C or SPI, and integrates four 1mA peripheral power switches, a 10mA host power switch, 256 bytes of SRAM, an 8-bit three-channel ADC, a 32-bit global time counter with alarm, a watchdog and a general-purpose event counter, with power-aware operation for energy-harvesting designs and a −40°C to +85°C operating range.

The company operates from Kristiansand, Norway, with a subsidiary in Porto, Portugal, and sells through a global network of distributors and sales representatives. Svein-Egil Nielsen is CEO.
