GD25Q80CSIG from GigaDevice Semicon Beijing, in a SOP-8-208mil. 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 | CS# | input | Chip Select Input; CS# must be driven high when the chip is not selected and must not be left floating at any time after power is on. |
| 2 | SO (IO1) | bidirectional | Data Output (Data Input Output 1) that serves as the serial data output in standard SPI and as IO1 in Dual/Quad SPI modes. |
| 3 | WP# (IO2) | bidirectional | Write Protect Input (Data Input Output 2) that serves as the write-protect control input and as IO2 in Quad SPI mode. |
| 4 | VSS | power_in | Ground reference pin for the device. |
| 5 | SI (IO0) | bidirectional | Data Input (Data Input Output 0) that serves as the serial data input in standard SPI and as IO0 in Dual/Quad SPI modes. |
| 6 | SCLK | input | Serial Clock Input that times all data transfers on the serial interface. |
| 7 | HOLD# (IO3) | bidirectional | Hold Input (Data Input Output 3) that pauses serial communication and as IO3 in Quad SPI mode. |
| 8 | VCC | power_in | Power Supply pin; single supply range stated as 2.7 to 3.6 V in the features section. |
