GC706AD 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 | Manual reset input, active low; pulling it below 0.8V triggers a RESET pulse, it 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 (1.0V to 5.5V operating range for GC706, absolute maximum -0.3 to +6.0V). |
| 3 | GND | power_in | 0V reference ground for all signals. |
| 4 | PFI | input | Power-fail monitor input; PFO goes low when PFI is below 1.25V, and PFI is tied to GND or VCC when unused. |
| 5 | PFO | output | Power-fail output that goes low and sinks current when PFI is below 1.25V, otherwise stays high. |
| 6 | WDI | input | Watchdog input; if held low or high for 1.6 s the watchdog times out and WDO goes low, and leaving it floating or on a high-impedance tri-state line disables the watchdog timer. |
| 7 | RESET | output | Active-low reset output that gives a 200ms low pulse when triggered and stays low while VCC is below the reset threshold (4.40V for GC706), holding low 200ms after VCC rises above it or MR goes high. |
| 8 | WDO | output | Watchdog output that goes low if the 1.6 s timer expires without being cleared and also while VCC is below the reset threshold, returning high immediately once VCC rises above the threshold. |
