STM6823TWY6F 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, push-pull reset output (RST-bar). Pulses low when triggered and stays low whenever VCC is below the reset threshold or when MR is a logic low. Remains low for t_rec after VCC rises above the reset threshold, the watchdog triggers a reset, or MR goes low-to-high. |
| 2 | VSS | power_in | Ground reference (0 V). |
| 3 | MR | input | Active-low push-button reset input (MR-bar). A logic low asserts the reset output; reset remains asserted while MR is low and for t_rec after MR returns high. Has an internal ~52 kohm pull-up; can be driven by TTL/CMOS logic or shorted to ground via a switch. May be left open or tied to VCC if unused. |
| 4 | WDI | input | Watchdog input. If WDI remains static (high or low) for at least 1.6 s (typ.), the internal watchdog timer expires and reset is asserted. A rising or falling edge on WDI clears the watchdog timer. Watchdog can be disabled by leaving WDI unconnected or driving from a tri-state buffer (leakage <= 10 uA, load <= 200 pF). |
| 5 | VCC | power_in | Supply voltage input. Monitored against the internal precision reset threshold (5, 3.3, 3, or 2.5 V variants). Typical supply current 3 uA; 0.1 uF decoupling capacitor to VSS recommended. |
