STM6905PWEDS6F from STMicroelectronics, in a MSOP-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 | Active-low manual (push-button) reset input with an internal 10 kΩ pull-up to VCC; RST is driven low while MR is low and remains low for tREC after MR returns high. |
| 2 | VCC | power_in | Primary supply voltage input (0.8 V to 5.5 V operating) and integrated fixed-threshold undervoltage monitor with factory-programmed reset thresholds from 3.078 V to 2.866 V. |
| 3 | V2IN | input | Second fixed-threshold voltage monitor input with factory-programmed reset thresholds from 2.333 V to 1.050 V. |
| 4 | VSS | power_in | Ground pin for the power supply. |
| 5 | V3IN | input | High-impedance adjustable reset comparator input; RST is driven low when the pin voltage falls below the 600 mV internal reference (VRSTIN 589 mV to 611 mV), with the trip point set by an external resistor divider. |
| 6 | V4IN | input | High-impedance adjustable reset comparator input; RST is driven low when the pin voltage falls below the 600 mV internal reference (VRSTIN 589 mV to 611 mV), with the trip point set by an external resistor divider. |
| 7 | V5IN | input | High-impedance adjustable reset comparator input; RST is driven low when the pin voltage falls below the 600 mV internal reference (VRSTIN 589 mV to 611 mV), with the trip point set by an external resistor divider. |
| 8 | RST | output | Active-low open-drain reset output that is driven low when any monitored supply falls below its threshold or MR is low; the datasheet calls for an external pull-up to VCC, with 10 kΩ suggested, and output is valid for VCC ≥ 0.8 V. |
