STM6321TWY6F from STMicroelectronics, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RST | output | Active-low, open-drain reset output for STM6321; pulses low when triggered and stays low whenever VCC is below the reset threshold, remaining low for trec after VCC rises above the reset threshold or a watchdog timeout occurs; requires an external pull-up resistor (e.g. 10 kΩ) to a supply up to 6 V. |
| 2 | VSS | power_in | Ground reference for the device. |
| 3 | RST | output | Active-high, push-pull reset output, the logical inverse of RST, asserted whenever VCC is below the reset threshold or a watchdog timeout occurs and remaining asserted for trec after VCC recovers. |
| 4 | WDI | input | Watchdog input; if WDI is held high or low for at least tWD = 1.6 s (typ.) the watchdog timer expires and RST is asserted, the timer is cleared by a reset or by any rising/falling edge on WDI (edges as short as 50 ns are detected), and the watchdog can be disabled by leaving WDI floating or driving it from a tri-state buffer (max. 10 µA leakage, 200 pF load). |
| 5 | VCC | power_in | Supply voltage input monitored by the precision comparator for the reset threshold; operating range 1.0 to 5.5 V per the DC/AC operating conditions, with typical quiescent supply current of a few µA. |
