STM6822TWY6F from STMicroelectronics, in a SOT-23-5L. 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; asserted (pulled low) when VCC falls below reset threshold (3.000-3.150 V for T-grade), MR is driven low, or watchdog timeout occurs; remains low for trec (140-280 ms typical); requires external pull-up resistor to any supply up to 6 V. |
| 2 | VSS | power_in | Ground; power supply return (0 V reference). |
| 3 | MR | input | Manual reset input (active low); internal 52 kΩ pull-up resistor; asserts reset when driven low; provides 100 ns glitch immunity; can be left open if unused or tied to VCC. |
| 4 | WDI | input | Watchdog timer input; triggers reset assertion if signal remains high or low for ≥1.6 s (typical); cleared by toggling (minimum 50 ns pulse width at VCC ≥ 3.0 V) or by reset assertion; can be disabled by leaving unconnected (max 10 µA leakage). |
| 5 | VCC | power_in | Positive supply voltage input; operating range 1.0 to 5.5 V; guaranteed reset assertion down to VCC = 1.0 V. |
