STM690AM6F 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 the external LPSRAM: connected to VCC through a 3 Ω PMOS switch when VCC is above the switchover voltage, and switched to VBAT through a 100 Ω switch when VCC falls below it. |
| 2 | VCC | power_in | Main supply voltage input for the 5 V operating device; reset is asserted when VCC falls below the reset threshold (VRST), and RST is guaranteed valid down to VCC = 1 V without a backup battery. |
| 3 | VSS | power_in | Ground reference for the device. |
| 4 | PFI | input | Power-fail comparator input: when PFI is below VPFI, or VCC falls below 2.4 V (or VSO), PFO goes low; connect to ground if unused. |
| 5 | PFO | output | Push-pull power-fail output that goes low when PFI is below VPFI or VCC falls below 2.4 V (or VSO); leave open if unused. |
| 6 | WDI | input | Watchdog input: if WDI stays high or low for 1.6 s (typ) a reset is triggered, and the watchdog is disabled when WDI is left floating (leakage at most 10 µA, load capacitance at most 200 pF when tri-stated). |
| 7 | RST | output | Active-low push-pull reset output that stays low while VCC is below the reset threshold or a watchdog reset occurs, and for trec (200 ms typ) after VCC rises above the threshold. |
| 8 | VBAT | power_in | Backup battery input that supplies VOUT when VCC falls below VSO; VBAT may exceed VCC, and it should be connected to VCC if no battery is used. |
