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 | Chip Select input, active low. Must be driven high when the device is not selected; do not leave floating after power-on. Selects the flash for all SPI/Dual/Quad transactions. |+| 2 | SO/IO1 | bidirectional | Standard SPI serial data output (SO). In Dual/Quad SPI modes this pin becomes bidirectional data line IO1. Data is shifted out on the falling edge of SCLK. |+| 3 | WP#/IO2 | bidirectional | Write Protect input (active low) that hardware-locks the status register when QE=0. When the non-volatile Quad Enable (QE) bit in the Status Register is set to 1, this pin becomes bidirectional Quad SPI data line IO2. |+| 4 | VSS | power_in | Ground reference for the device. Connect directly to system ground. |+| 5 | SI/IO0 | bidirectional | Standard SPI serial data input (SI); latched on the rising edge of SCLK. In Dual/Quad SPI modes this pin becomes bidirectional data line IO0. |+| 6 | SCLK | input | Serial clock input; supports SPI modes 0 and 3, up to 133 MHz (with 30 pF load, VCC 3.0-3.6 V). Input data is latched on the rising edge and output data shifts on the falling edge. |+| 7 | HOLD#/IO3 | bidirectional | Hold input (active low) that pauses serial communication without deselecting the device when QE=0. When QE=1, this pin becomes bidirectional Quad SPI data line IO3. |+| 8 | VCC | power_in | Single power supply, 2.7 V to 3.6 V (full voltage range). Requires local decoupling; device auto-resets below the write-inhibit threshold VWI. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | GigaDevice Semicon Beijing |+| Package | SOP-8-208mil |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `GD25Q16ESIGRETIG`+- `GD25Q16ESIGRETJG`+- `GD25Q16ESIGRETEG`+- `GD25Q16ESIGRETFG`+- `GD25Q16ESIGRESIG`+- `GD25Q16ESIGRESJG`+- `GD25Q16ESIGRESEG`+- `GD25Q16ESIGRESFG`+- `GD25Q16ESIGREEIG`+- `GD25Q16ESIGREEJG`+- `GD25Q16ESIGREEEG`+- `GD25Q16ESIGREEFG`+- `GD25Q16ESIGRENIG`+- `GD25Q16ESIGRENJG`+- `GD25Q16ESIGRENEG`+- `GD25Q16ESIGRENFG`+- `GD25Q16ESIGREQIG`+- `GD25Q16ESIGREQJG`+- `GD25Q16ESIGREQEG`+- `GD25Q16ESIGREQFG`+- `GD25Q16ESIGREWIG`+- `GD25Q16ESIGREWJG`+- `GD25Q16ESIGREWEG`+- `GD25Q16ESIGREWFG`++## CAD (KiCad official)++- Symbol: `GD25Q16ESIGR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8-208mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [GigaDevice Semicon Beijing datasheet](docs/gd25q16esigr-datasheet.pdf) (58 pp, sha256 `e664882f90d940a2`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
