STM802SM6F 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 | VOUT | power_out | Supply output for external LPSRAM: connected to VCC through a P-channel switch when VCC is above VSO, and switched to VBAT when VCC falls below VSO; connect to VCC if no battery is used. |
| 2 | VCC | power_in | Supply voltage input; without a backup battery, RST is guaranteed valid down to VCC = 1 V. |
| 3 | VSS | power_in | Ground reference for the device. |
| 4 | PFI | input | Power-fail input: PFO goes low when PFI is less than VPFI (or VCC falls below VSW = 2.4 V), and PFI is disabled in battery backup; connect to ground if unused. |
| 5 | PFO | output | Push-pull power-fail output that goes low when PFI is less than VPFI or VCC falls below VSW; leave open if unused. |
| 6 | WDI | input | Watchdog input: if WDI stays high or low for 1.6 s (typ) the watchdog triggers a reset, and the watchdog cannot be disabled by letting WDI float. |
| 7 | RST | output | Active-low reset output that pulses low for trec when triggered and stays low while VCC is below the reset threshold or MR is low. |
| 8 | VBAT | power_in | Backup battery input that connects to VOUT when VCC falls below VSO; VBAT may exceed VCC, and it should be connected to VCC if no battery is used. |
