STM690TM6F from STMicroelectronics, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; 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 MOSFET switch when VCC is above the switchover voltage (VSO); switches to VBAT when VCC falls below VSO. Connect to VCC if no battery is used. |
| 2 | VCC | power_in | Primary +3 V supply voltage input. Monitored by internal precision comparator against the reset threshold; when it falls out of tolerance the reset output is asserted. |
| 3 | VSS | power_in | Ground return for the device. |
| 4 | PFI | input | Power-fail comparator input. When PFI is less than VPFI (typ 1.25 V) or VCC falls below VSW (2.4 V), PFO is driven low; otherwise PFO is high. Connect to ground if unused. |
| 5 | PFO | output | Active-low power-fail output (push-pull). Goes low when PFI is below VPFI or VCC falls below VSW; otherwise stays high. Leave open if unused. |
| 6 | WDI | input | Watchdog input. If WDI stays high or low for 1.6 s (typ) the internal watchdog runs out and reset is triggered. The watchdog timer clears on a rising/falling edge of WDI or while reset is asserted. Cannot be disabled by floating. |
| 7 | RST | output | Active-low reset output (push-pull). Pulses low for trec (200 ms typ) when triggered and stays low whenever VCC is below the reset threshold or MR is low. Held low for trec after VCC recovers, the watchdog trips, or MR returns high. |
| 8 | VBAT | power_in | Backup battery input. When VCC falls below VSO, VOUT switches from VCC to VBAT; when VCC rises above VSO + hysteresis, VOUT reconnects to VCC. VBAT may exceed VCC. Connect to VCC if no battery is used. |
