SP705EN-L from MSKSEMI, in a SOP-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; a low pulse of at least 500 ns forces the reset output active. |
| 2 | VCC | power_in | Power supply input; SP705 operates from 5.0V to 5.5V. |
| 3 | GND | power_in | Ground. |
| 4 | PFI | input | Inverting input of the internal 1.25V power-fail comparator, with a threshold of 1.2V min, 1.25V typ and 1.3V max. |
| 5 | !PFO | output | Output of the internal 1.25V power-fail comparator. |
| 6 | WDI | input | Watchdog input with a 1.6s typical watchdog timeout; leaving the pin floating disables the watchdog function. |
| 7 | !RESET | output | Active-low reset signal output, asserted when VCC falls below the reset threshold or !MR is low, with a 200ms typical reset pulse width. |
| 8 | !WDO | output | Watchdog output, which goes low when the watchdog timer expires. |
