STM705M6F

STMicroelectronics · Supervisor And Reset ICs · SO-8

STM705M6F from STMicroelectronics, in a SO-8. 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 MR input A logic low on MR asserts reset, which remains asserted while MR is low and for trec after it returns high, and the input has an internal pull-up so it may be left open if unused.
2 VCC power_in Supply voltage monitored against the reset threshold VRST, with an operating range of 1.2 V to 5.5 V per Table 6.
3 VSS power_in Ground reference for the device.
4 PFI input Power-fail input compared to an internal threshold VPFI of 1.20 V to 1.30 V; PFO goes low when PFI is below VPFI, and PFI should be connected to VSS if the comparator is unused.
5 PFO output Push-pull power-fail output that goes low when PFI is less than VPFI and otherwise remains high, and it may be left open if unused.
6 WDI input Watchdog input; if WDI stays high or low for 1.6 s the watchdog times out and triggers reset (or WDO), and the watchdog is disabled by letting WDI float.
7 RST output Active-low reset output that is forced low when VCC is below the reset threshold or MR is low, and remains low for trec after VCC rises above the threshold or MR returns high.
8 WDO output Push-pull watchdog output that goes low when WDI is not toggled within 1.6 s or when VCC falls below the reset threshold, and goes high as soon as VCC exceeds the reset threshold.
