STM6822RWY6F 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 STM6822; pulses low when triggered and stays low while VCC is below the reset threshold or MR is low, remaining low for trec after VCC rises above threshold, a watchdog timeout, or MR going high; requires an external pull-up resistor to a supply up to 6 V. |
| 2 | VSS | power_in | Ground reference for the device. |
| 3 | MR | input | Active-low push-button manual reset input with an internal 52 kΩ pull-up; a logic low asserts RST and reset stays asserted while MR is low and for trec after it returns high; can be driven by TTL/CMOS logic or a switch to ground, and may be left open if unused. |
| 4 | WDI | input | Watchdog timer input; if it remains high or low for at least the 1.6 s (typ.) watchdog timeout period, RST is asserted, and the timer is cleared by a rising or falling edge on WDI or while reset is asserted; the watchdog can be disabled by leaving WDI unconnected or driving it from a tristate output. |
| 5 | VCC | power_in | Supply voltage input monitored by the precision comparator for the reset threshold; operating range 1.0 V to 5.5 V per DC/AC conditions. |
