Energy Micro

Energy Micro was a Norwegian fabless semiconductor company, founded in 2007 and headquartered in Oslo, best known for its EFM32 "Gecko" family of energy-friendly 32-bit ARM Cortex-M microcontrollers and the EFR radio products targeting low-power embedded and IoT applications. The company was acquired by Silicon Labs in 2013 and fully absorbed into that company's product lines; its former energymicro.com domain now redirects to silabs.com. It was surfaced as a portfolio company of Northzone and added to the API Evangelist network as a stub. Enrichment found no independent, first-party API, developer portal, OpenAPI, SDK, or MCP surface for Energy Micro as a standalone entity — the developer tooling for its EFM32 line lives under Silicon Labs today.

Energy Micro is profiled on the APIs.io network. Tagged areas include Company, Enterprise, Semiconductors, Microcontrollers, and Embedded.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/energy-micro: open an issue to ask a question, or submit a pull request to add artifacts.
