STM802TM6F from STMicroelectronics, in a SOIC-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. When VCC is above the switchover voltage (VSO), VOUT is connected to VCC through an internal P-channel MOSFET switch; when VCC falls below VSO, VBAT is connected to VOUT. Connect to VCC if no backup battery is used. |
| 2 | VCC | power_in | Primary +3 V supply voltage input monitored by the reset comparator. When VCC falls below the reset threshold, RST is asserted; when VCC falls below VSO, the internal switch transfers VOUT to VBAT. |
| 3 | VSS | power_in | Device ground reference (0 V). |
| 4 | PFI | input | Power-fail comparator input. When PFI is less than VPFI (nominal 1.25 V), or when VCC falls below VSW (2.4 V), PFO is driven low; otherwise PFO remains high. Connect to ground if unused. |
| 5 | PFO | output | Power-fail output (active-low, push-pull). Goes low when PFI drops below VPFI or VCC falls below VSW; used as an early warning of impending power failure. Leave open if unused. |
| 6 | WDI | input | Watchdog input. If WDI remains high or low for ~1.6 s the internal watchdog timer expires and triggers a reset. The timer clears on any rising or falling edge on WDI, or while reset is asserted. The watchdog cannot be disabled by floating WDI. |
| 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 the watchdog trips. Guaranteed valid down to VCC = 1.0 V. |
| 8 | VBAT | power_in | Backup battery input. When VCC falls below VSO, VOUT is switched from VCC to VBAT; VOUT reconnects to VCC when VCC rises above VSO plus hysteresis. VBAT may exceed VCC. Connect to VCC if no battery is used. |
