Nanopower cuts IoT energy 90%
Nanopower says its nPZero PSIC is entering volume production and will slash IoT energy use by roughly 90% using a 'shadow' MCU control approach plus no‑code tools — a potential game changer for battery‑operated sensors ElecNotes. The company’s pitch at Embedded World framed the chip as a direct answer to years of power‑budget limitations in distributed IoT deployments ElecNotes.
Nanopower announced)) its latest update on March 10, 2026, and said samples and development kits for the nPZero are immediately available to designers. The company’s nPZero Development Kit is modular with four boards and an Arduino-format host header, and the main dev board supports two SPI and two I²C sensors and can be powered by a CR2032 coin cell or USB‑C. ([nanopowersemi.com)] Early demos linked the nPZero to Nordic Semiconductor’s nRF54 wireless MCU as a reference host during evaluations, showing how the PSIC can sit between a radio SoC and peripherals. ([prnewswire.com)] Nanopower describes the chip as autonomously handling power‑up, configuration and data reads for peripherals—then returning control to the host only when user‑defined rules fire—capabilities detailed in its product literature and PR materials. ([prnewswire.com)] Independent coverage and the EPDT technical brief note the device can operate with intervals down to about 0.6 seconds and monitor up to four I²C/SPI sensors while remaining in the nanoamp range during idle monitoring. ([epdtonthenet.net)] Nanopower is a Norwegian fabless company headquartered in Kristiansand, founded in 2017, and its nPZero was named an EPDT 2025 Product of the Year in January 2026. ([pitchbook.com)] At Embedded World the company is exhibiting in Hall 4, Booth 4‑460, and its March PR frames the product as enabling OEMs to move from evaluation kits to higher‑volume deployments.
