STM813LM6F

STMicroelectronics · Supervisor And Reset ICs · SO-8

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.
