# New on the Nanopower DevPortal: Updated APIs, Datasheets & Errata for nPZero G1S

Designing ultra-low-power embedded systems requires accurate documentation, reliable software, and up-to-date technical information. That's why Nanopower has expanded the resources available on the **Nanopower DevPortal**, making it easier than ever to evaluate, integrate and design with the **nPZero G1S** power-saving IC. (PSIC)

The latest DevPortal updates include:

- **Updated APIs** for faster firmware integration and simplified device configuration.
- **Revised Datasheets** with enhanced electrical specifications, operating conditions, register descriptions, application diagrams and ordering information.
- **Latest Errata** providing transparent documentation of known issues, recommended workarounds and implementation guidance.
- **Additional documentation**, example code, development tools and application resources to support your design from evaluation through to production.

Together, these updates help engineers reduce development time, minimise integration risk and accelerate design-in.

The **nPZero G1S** autonomously manages up to four I²C or SPI sensors while allowing the host MCU to remain completely powered down until needed. With **100 nA idle current** and **1 µA polling current**, nPZero enables dramatic reductions in system power consumption for battery-powered and energy-harvesting applications.

### Get Started

**Download the latest APIs, datasheets and errata:**  
[https://dev.nanopowersemi.com/](https://dev.nanopowersemi.com/)

**Purchase an nPZero Development Kit** and start evaluating nPZero in your own application:  
[https://www.nanopowersemi.com/development-kit](https://www.nanopowersemi.com/development-kit)

**Find an authorised distributor or sales partner:**
