STM704TM6F from STMicroelectronics, in a SO-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 voltage for external LPSRAM connected to VCC through P-channel MOSFET switch when VCC is above switchover voltage VSO, or to VBAT when VCC falls below VSO. |
| 2 | VCC | power_in | Supply voltage input with operating range 1.1 to 5.5 V for supervisor circuit operation. |
| 3 | VSS | power_in | Ground reference and return path for supply voltage. |
| 4 | PFI | input | Power-fail input that triggers PFO output low when PFI is less than internal threshold VPFI (typ 1.237 V) or VCC falls below 2.4 V. |
| 5 | PFO | output | Power-fail output (push-pull) that goes low when PFI is less than VPFI or VCC falls below switchover voltage 2.4 V, otherwise remains high. |
| 6 | MR | input | Manual reset input (active-low) with internal 40 kΩ pull-up that asserts RST when pulled low and for trec (typ 200 ms) after returning high. |
| 7 | RST | output | Active-low reset output that stays low whenever VCC is below reset threshold (3.075 V typ for STM704T) or MR is held low, and remains asserted for trec after recovery. |
| 8 | VBAT | power_in | Backup battery input that switches to VOUT when VCC falls below switchover voltage VSO (2.4 V typical), may exceed VCC in voltage. |
