Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | /CS | input | Active-low SPI Chip Select input. Drive low to select the device and clock in instructions on CLK; drive high to deselect and place DO/IO pins into Hi-Z. After power-up /CS must transition high-to-low before the first instruction; a pull-up to VCC is recommended. |+| 2 | DO (IO1) | bidirectional | Serial Data Output in Standard SPI mode (data shifts out on falling edge of CLK). Becomes bidirectional IO1 for Dual/Quad SPI instructions. |+| 3 | /WP (IO2) | bidirectional | Active-low Write Protect input, used with Status Register CMP/SEC/TB/BP2/BP1/BP0/SRP0 bits to hardware-protect part or all of the array. Becomes bidirectional IO2 when Quad Enable (QE) bit is set for Quad SPI I/O. |+| 4 | GND | power_in | Device ground reference (0 V). |+| 5 | DI (IO0) | bidirectional | Serial Data Input in Standard SPI mode (instructions, addresses and data clocked in on rising edge of CLK). Becomes bidirectional IO0 for Dual/Quad SPI instructions. |+| 6 | CLK | input | SPI Serial Clock input. Provides timing for serial input and output; up to 104MHz on W25Q80DV. Data is latched on rising edge and shifted out on falling edge. |+| 7 | /HOLD (IO3) | bidirectional | Active-low Hold input pauses serial communication while /CS is low: DO goes Hi-Z and DI/CLK are ignored. Becomes bidirectional IO3 when Quad Enable (QE) bit is set for Quad SPI I/O. |+| 8 | VCC | power_in | Power supply input. W25Q80DV: 2.7 V to 3.6 V (single supply). Decouple to GND with a local bypass capacitor near the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Winbond Elec |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `W25Q80DVSNIG`+- `W25Q80DVSNIGSS`+- `W25Q80DVSNIGSV`+- `W25Q80DVSNIGZP`+- `W25Q80DVSNIGUX`+- `W25Q80DVSNIGUXIE`+- `W25Q80DVSNIGDA`+- `W25Q80DVSNIGBY`++## CAD (KiCad official)++- Symbol: `W25Q80DVSNIG`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Winbond Elec datasheet](docs/w25q80dvsnig-datasheet.pdf) (73 pp, sha256 `7f8c606061fa6b81`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
