STMicroelectronics · Supervisor And Reset ICs · SOT-23-5
STM6823ZWY6F from STMicroelectronics, in a SOT-23-5. 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 | RST | output | Active low, push-pull reset output that pulses low when triggered and stays low whenever VCC is below the reset threshold or MR is logic low, remaining low for trec after VCC recovers, a watchdog reset, or MR returns high. |
| 2 | VSS | power_in | Ground reference for the supervisor (GND). |
| 3 | MR | input | Active low push-pull reset input; a logic low asserts reset and reset stays asserted while MR is low and for trec after it returns high, with an internal 52 kΩ pull-up (35 to 75 kΩ) so it may be left open if unused. |
| 4 | WDI | input | Watchdog input; if WDI stays high or low for at least 1.6 s (typ.) reset is asserted, the timer clears on any rising or falling edge (pulses as short as 50 ns), and leaving WDI unconnected disables the watchdog. |
| 5 | VCC | power_in | Supply voltage with operating range 1.2 V to 5.5 V (reset guaranteed valid down to VCC = 1.0 V for TA = 0 to 85 °C); absolute maximum VCC is 7.0 V. |
