DIO706SCS8 from DIOO, in a SOIC-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 | MR | input | Manual reset input: pulling it low triggers a reset pulse, it has an internal pull-up current (100 to 600 uA at VCC=5V with MR=0V), and it can be driven by TTL or CMOS logic or shorted to GND by a switch. |
| 2 | VCC | power_in | Positive supply input, operating from 1.15 V to 5.5 V, and monitored against the reset threshold (2.93 V for the DIO706S). |
| 3 | GND | power_in | Negative supply (ground) input. |
| 4 | PFI | input | Power-fail monitor input: PFO goes low when PFI is below its 1.22 V threshold (1.184 V to 1.256 V), and PFI should be connected to GND or VCC when not used. |
| 5 | PFO | output | Power-fail monitor output that goes low when the voltage at PFI is below 1.22 V and goes high otherwise. |
| 6 | WDI | input | Watchdog input: if WDI stays high or low for 1.6 s the watchdog times out and WDO goes low, while floating or three-stating WDI disables the watchdog function. |
| 7 | RESET | output | Active-low reset output that stays low while VCC is below the reset threshold and for 200 ms after VCC rises above the threshold or MR goes from low to high. |
| 8 | WDO | output | Watchdog output that goes low when the watchdog timer completes its 1.6 s count and stays low while VCC is below the reset threshold, returning high without delay once VCC rises above it. |
