STM811RW16F from STMicroelectronics, in a SOT-143. 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 reset output; asserts reset (pulls low) when VCC drops below reset threshold VRST or when MR goes low; guaranteed valid down to VCC = 1.0 V; minimum pulse width 140 ms |
| 2 | VSS | power_in | Ground connection (0 V reference) |
| 3 | MR | input | Manual reset input with internal 20 kΩ pull-up resistor; logic low asserts RST and keeps it low for minimum trec after MR returns high |
| 4 | VCC | power_in | Power supply voltage input; operating range 1.2 V to 5.5 V at -40 to 85 °C, or 1.0 V to 5.5 V at 0 to 70 °C |
