GC705AD from Sungine, in a DIP-8L. 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 | Active-low manual reset input that triggers a RESET pulse when pulled below 0.8V, has an internal 250uA pull-up, and can be driven by TTL/CMOS logic or a switch to ground. |
| 2 | VCC | power_in | +5V supply input (absolute maximum -0.3 to +6.0V relative to GND). |
| 3 | GND | power_in | 0V reference ground for all signals. |
| 4 | PFI | input | Power-fail monitor input with 1.25V threshold, PFO goes low when PFI is below 1.25V; connect to GND or VCC when unused. |
| 5 | PFO | output | Power-fail output that goes low (sinking current) when PFI is below 1.25V and stays high otherwise. |
| 6 | WDI | input | Watchdog input; if held low or high for 1.6s the watchdog times out and WDO goes low, and leaving it floating or on a high-impedance three-state line disables the watchdog. |
| 7 | RESET | output | Active-low reset output that gives a 200ms pulse when triggered and stays low while VCC is below the reset threshold (4.65V for GC705), and the 200ms low time continues after VCC rises above the threshold or MR goes high. |
| 8 | WDO | output | Watchdog output that goes low if the 1.6s watchdog timer is not cleared and also whenever VCC is below the reset threshold, returning high immediately once VCC rises above the threshold. |
