This is the most relevant entry I found related to your question. Quoting Flux documentation:

“2. Look Up a Component's Datasheet

Ensure Copilot references the correct datasheet by mentioning a specific part in your design:

@U1 What is the input voltage range for this component?

@U3 How do I configure an interrupt on this microcontroller?

Tip: If the component has a Datasheet URL in Flux, Copilot will automatically read it.” Source

I can’t directly download files for you from Flux. Here’s the direct datasheet URL so you can open it and save it locally:

I couldn’t find documentation for an in-Flux “download datasheet” action. For reference:

I can’t download files on your behalf. I also couldn’t find documentation for an in‑editor “download” action. The Flux docs only note that Copilot reads the Datasheet URL if present:

“Tip: If the component has a Datasheet URL in Flux, Copilot will automatically read it.” Source

If you want, I can pull specific specs or tables from this datasheet for you.
