# STM795TM6F

**STMicroelectronics** · Supervisor And Reset ICs · SO-8

STM795TM6F 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: VOUT connects to VCC through a P-channel MOSFET switch when VCC is above VSO, switches to VBAT when VCC falls below VSO, and should be connected to VCC if no battery is used. |
| 2 | VCC | power_in | Supply voltage input; RST is asserted whenever VCC is below the reset threshold VRST and is guaranteed valid down to VCC = 1 V when no backup battery is used. |
| 3 | Vccsw | output | Push-pull output that goes high when VOUT switches to the battery and low when it switches back to VCC, and can drive an external PMOS transistor for IOUT requirements above 75 mA. |
| 4 | VSS | power_in | Ground reference pin for the device. |
| 5 | E | input | Input to the chip enable gating circuit, which should be connected to ground if unused. |
| 6 | ECON | output | Conditional chip enable output that goes low only when E is low and reset is not asserted, remains low for 15 µs or until E goes high if reset is asserted while low, and is pulled up to VOUT in the disabled mode. |
| 7 | RST | output | Active-low reset output that pulses low for trec when triggered and stays low whenever VCC is below the reset threshold or MR is a logic low. |
| 8 | VBAT | power_in | Backup battery input that connects to VOUT when VCC falls below VSO; it may exceed VCC and should be connected to VCC if no battery is used. |
