# Manufacturer-first (ST / TI / Nordic / NXP / Microchip / …)

The manufacturer is the **authoritative** source for the full family, the latest datasheet, and
official 3D STEP. chip-fetcher's ladder starts here. Native browser matters because several
manufacturer datasheet CDNs **curl-block** but serve a real browser (use `fetch().arrayBuffer()`
inside the page to grab the PDF with the browser's fingerprint).

## ST example — the VL53Lx ToF family

```
ST's product-selector table lists every orderable variant + datasheet + STEP. Extract the family:
```js
[...document.querySelectorAll("a,td")].map(e=>e.textContent).join(" ").match(/\bVL53L[0-9][A-Z0-9]+\b/g)
```
Cross-check the manufacturer family against the DigiKey/Mouser parametric pull to catch NRND/new
variants. Then hand each MPN to chip-fetcher for the CAD bundle.
