STM1001RWX6F

STMicroelectronics · Supervisor and Reset ICs · SOT-23

STM1001RWX6F from STMicroelectronics, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RST output Active-low reset output, open-drain. Asserted low whenever VCC drops below the preset reset threshold (VRST) and held low for at least trec (30 ms or 140 ms min, ~210 ms typ) after VCC recovers. Requires an external pull-up resistor to VCC. Guaranteed valid down to VCC = 1.0 V.
2 VCC power_in Supply voltage input, also the monitored rail. Nominal 3 V / 3.3 V / 5 V depending on threshold suffix (R = 2.55-2.70 V trip for STM1001RWX6F, typical 2.63 V). A 0.1 µF bypass capacitor mounted close to this pin is recommended for transient immunity.
3 VSS power_in Ground reference for the device.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
stm1001rwx6f.step 59 KB You want the bare part, or you mark your own boards.
stm1001rwx6f-etched.step 2.0 MB You want the part with STM1001RWX6F already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 493 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: STMicroelectronics datasheet (18 pp, sha256 232a6aa7f56a92be, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
