Uhnder

Uhnder is an Austin, Texas fabless semiconductor company founded in 2015 that designs the S80 and S81 77 GHz 4D digital imaging Radar-on-Chip (RoC) for automotive ADAS and automated mobility. Its Digital Code Modulation (DCM) approach on a 28nm RF CMOS process replaces analog FMCW radar with a software-defined sensor, and each RoC ships with an ASPICE-qualified Software Development Kit carrying ready-to-integrate software APIs, on-chip user algorithm support and system tools for Tier-1 and OEM radar stacks. Uhnder is a chip supplier rather than a web-API provider: the SDK and its APIs are embedded interfaces delivered under a commercial customer relationship, and the company publishes no public developer portal, documentation host or machine-readable API contract.

Uhnder is profiled on the APIs.io network. Tagged areas include Company, Semiconductors, Automotive, Radar, and ADAS.

Uhnder’s developer surface includes support and 10 more developer resources.

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.

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/uhnder: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: Uhnder's S80/S81 product briefs advertise an "ASPICE Qualified SDK with Ready-to-Integrate APIs", but the SDK is
    only obtainable through a commercial automotive customer relationship — the products page offers no download, registration
    or documentation link, only info@uhnder.com, and every candidate developer host (developer./docs./api./portal./sdk.uhnder.com)
    is NXDOMAIN.
