STM6779SWB6F from STMicroelectronics, in a SOT-23-6. 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; driven low when VCC1 or RSTIN falls below its threshold or when MR is asserted; remains low for trec after all monitored supplies recover above thresholds and MR returns high. |
| 2 | VSS | power_in | Ground; negative supply reference. |
| 3 | MR | input | Active-low push-button reset input with internal 50 kΩ pull-up resistor to VCC1; driving low asserts RST and maintains it low for trec after release. |
| 4 | MRC | input | Manual reset delay input; leave open for 6 µs minimum delay or connect capacitor to VSS to implement delays from microseconds to seconds depending on capacitor value. |
| 5 | RSTIN | input | Adjustable reset comparator input (high impedance); monitors external threshold set via resistor divider network; asserts RST when voltage falls below 0.626 V internal reference. |
| 6 | VCC1 | power_in | Primary supply voltage monitoring input; reset threshold factory-programmed based on device suffix (4.63 V to 1.58 V range); also provides reference for push-pull RST outputs on other variants. |
