STMicroelectronics · Supervisor And Reset ICs · SOT-23-5
STM6321MAWY6F 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 open drain reset output that pulses low when triggered, stays low while VCC is below the reset threshold, and needs a pull-up resistor to a supply up to 6 V. |
| 2 | VSS | power_in | Ground. |
| 3 | RST (active high) | output | Active high push-pull reset output, the inverse of the active low RST output. |
| 4 | WDI | input | Watchdog input that asserts reset if it stays high or low for 1.6 s (typ.) and can be disabled by leaving it unconnected or tristated. |
| 5 | VCC | power_in | Supply voltage monitored against the reset threshold, with an absolute maximum of 7.0 V and an operating range of 1.0 to 5.5 V. |
