STM813LM6F from STMicroelectronics, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | MR | input | Active-low push-button reset input with 40 kΩ internal pull-up; asserts reset while low and for 200 ms (typical) after release. |
| 2 | VCC | power_in | Supply voltage input for 5 V supervisor with 1.0-5.5 V operating range and 40 μA (typical) quiescent current. |
| 3 | VSS | power_in | Ground reference. |
| 4 | PFI | input | Power-fail comparator input; triggers output PFO low when voltage falls below 1.25 V (typical) threshold. |
| 5 | PFO | output | Power-fail output (push-pull, active-low); goes low when PFI < 1.25 V (typical) with 2 μs propagation delay. |
| 6 | WDI | input | Watchdog input; requires edge transitions every 1.6 s (typical) to prevent watchdog timeout; function disabled by floating pin. |
| 7 | RST | output | Active-high reset output; asserts high when VCC < 4.63 V (typical) or manual reset input MR pulled low or watchdog timer times out; remains high for 200 ms (typical). |
| 8 | WDO | output | Watchdog output (push-pull, active-low); goes low on 1.6 s (typical) watchdog timeout or when VCC < 4.63 V (typical); returns high after WDI edge transition. |
