STMicroelectronics · Supervisor And Reset ICs · SOT-143-4
STM812SW16F from STMicroelectronics, in a SOT-143-4. 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 | VSS | power_in | Ground reference for the device. |
| 2 | RST | output | Active-high push-pull reset output on the STM812, asserted when VCC falls below the reset threshold or MR is low, and held for trec (140 ms min) afterwards; valid down to VCC = 1.0 V (0 to 70 °C). |
| 3 | MR | input | Active-low manual reset input with internal 20 kΩ pull-up (10 to 30 kΩ), which can be left open if unused; a low level of at least 10 µs asserts reset. |
| 4 | VCC | power_in | Supply voltage input, operating range 1.0 to 5.5 V (1.2 V to 5.5 V over -40 to 85 °C), absolute maximum 7.0 V. |
