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 enable device access; when high the device is deselected and DO/IO pins are high-Z. /CS must track VCC at power-up (per power-up timing). |+| 2 | DO/IO1 | bidirectional | Standard SPI serial data output (DO); in Dual/Quad SPI modes acts as bidirectional IO1. In Standard/Dual SPI this pin is DO; when QE=1 in Status Register-2 it becomes IO1 for Quad SPI. |+| 3 | /WP/IO2 | bidirectional | Active-low hardware Write Protect input in Standard/Dual SPI, used with the Status Register Block Protect (CMP/SEC/TB/BP2/BP1/BP0) and SRP0 bits. Becomes bidirectional IO2 for Quad SPI when the Quad Enable (QE) bit is set. |+| 4 | GND | power_in | Device ground reference for all logic and I/O signaling. |+| 5 | DI/IO0 | bidirectional | Standard SPI serial data input (DI); latched on rising edge of CLK. In Dual/Quad SPI acts as bidirectional IO0 for command, address, and data phases. |+| 6 | CLK | input | SPI Serial Clock input, up to 104 MHz. Provides timing for serial input/output; data on DI/IOx is latched on rising edge, data on DO/IOx is shifted out on falling edge. |+| 7 | /HOLD/IO3 | bidirectional | Active-low Hold input in Standard/Dual SPI: while /CS is low, driving /HOLD low pauses the device with DO high-Z and DI/CLK ignored. Becomes bidirectional IO3 for Quad SPI when the Quad Enable (QE) bit in Status Register-2 is set. |+| 8 | VCC | power_in | Main power supply, 2.7V to 3.6V single-supply. Decouple with a local bypass capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Winbond |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `W25Q80DVSNIG TRSN`+- `W25Q80DVSNIG TRSS`+- `W25Q80DVSNIG TRSV`+- `W25Q80DVSNIG TRZP`+- `W25Q80DVSNIG TRUX`+- `W25Q80DVSNIG TRUXIE`+- `W25Q80DVSNIG TRDA`+- `W25Q80DVSNIG TRBY`++## CAD (KiCad official)++- Symbol: `W25Q80DVSNIG TR`+- 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 datasheet](docs/w25q80dvsnig-tr-datasheet.pdf) (71 pp, sha256 `3300ea3e9d2cda4e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
