A Battery-less 507nW SoC with Integrated Platform Power Manager and SiP Interfaces

A 507nW self-powered SoC is demonstrated for ultra-low power (ULP) internet-of-things (IoT) applications. The SoC includes ULP system-in-package (SiP) interfaces that enable its harmonious integration with a radio transmitter (TX) and a non-volatile memory (NVM). The energy harvesting platform power manager (EH-PPM) powers the SoC as well as off-chip components and is optimized for low quiescent power. It supplies the SoC with 0.5V, 1.0V, and 1.8V and can also power ULP sensors and the SiP components while running an example shipping-integrity tracking algorithm. A power monitor (PM) cold-boots the SoC from NVM and adapts the system’s power consumption. The tight integration between the SoC’s blocks enables sub-µW operation.
