STM6321RWY6F

STMicroelectronics · Supervisor And Reset ICs · SOT-23-5

STM6321RWY6F from STMicroelectronics, in a SOT-23-5. 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 on the STM6321 that pulses low when triggered and stays low while VCC is below the reset threshold, then remains low for trec after VCC rises above the threshold or the watchdog triggers; requires a pull-up resistor to a supply up to 6 V.
2 VSS power_in Ground.
3 RST (active high) output Active high, push-pull reset output that is the inverse of RST.
4 WDI input Watchdog input that asserts reset if it stays high or low for at least 1.6 s, clears the timer on a rising or falling edge, and disables the watchdog if left unconnected or driven by a tristate buffer.
5 VCC power_in Supply voltage monitored against the reset threshold, with an absolute maximum of 7.0 V and operation from 1.2 V to 5.5 V (1.0 V minimum for TA = 0 to +85 °C).
