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 chip is not selected; do not leave floating after power-on. Enables/disables device serial communications. |+| 2 | SO/IO1 | bidirectional | Serial Data Output in Standard SPI mode. Acts as bidirectional Data Input/Output 1 (IO1) in Dual and Quad SPI modes. |+| 3 | WP#/IO2 | bidirectional | Active-low Write Protect input in Standard/Dual SPI (hardware-protects the Block Protect bits BP4-BP0 and SRP0/SRP1). Becomes bidirectional Data I/O 2 (IO2) in Quad SPI mode when QE=1 in the Status Register. |+| 4 | VSS | power_in | Ground reference for all signals and power supply. |+| 5 | SI/IO0 | bidirectional | Serial Data Input in Standard SPI mode. Acts as bidirectional Data Input/Output 0 (IO0) in Dual and Quad SPI modes. Input data is latched on the rising edge of SCLK. |+| 6 | SCLK | input | Serial Clock input. Provides the timing of the serial interface; supports SPI modes 0 and 3, up to 133MHz for fast read. |+| 7 | HOLD#/IO3 | bidirectional | Active-low HOLD input in Standard/Dual SPI mode (pauses serial communication without deselecting the device). Becomes bidirectional Data I/O 3 (IO3) in Quad SPI mode when QE=1. |+| 8 | VCC | power_in | Power supply input, single supply 2.7V to 3.6V. Typical standby current 12uA; deep power-down current ~1uA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | GigaDevice Semicon Beijing |+| Package | SOP-8-208mil |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `GD25Q64ESIGRESIG`+- `GD25Q64ESIGRESIGR`+- `GD25Q64ESIGRESIGT`+- `GD25Q64ESIGRESIGY`+- `GD25Q64ESIGRESJG`+- `GD25Q64ESIGRESEG`+- `GD25Q64ESIGRESFG`+- `GD25Q64ESIGRETIG`+- `GD25Q64ESIGRETJG`+- `GD25Q64ESIGRETEG`+- `GD25Q64ESIGRETFG`+- `GD25Q64ESIGRENIG`+- `GD25Q64ESIGRENJG`+- `GD25Q64ESIGRENEG`+- `GD25Q64ESIGRENFG`+- `GD25Q64ESIGREQIG`+- `GD25Q64ESIGREQJG`+- `GD25Q64ESIGREQEG`+- `GD25Q64ESIGREQFG`+- `GD25Q64ESIGREWIG`+- `GD25Q64ESIGREWJG`+- `GD25Q64ESIGREWEG`+- `GD25Q64ESIGREWFG`+- `GD25Q64ESIGREYIG`+- `GD25Q64ESIGREYJG`+- `GD25Q64ESIGREYEG`+- `GD25Q64ESIGREYFG`+- `GD25Q64ESIGREFIG`+- `GD25Q64ESIGREFJG`+- `GD25Q64ESIGREFEG`+- `GD25Q64ESIGREFFG`+- `GD25Q64ESIGREZIG`+- `GD25Q64ESIGREZJG`+- `GD25Q64ESIGREZEG`+- `GD25Q64ESIGREZFG`+- `GD25Q64ESIGREBIG`+- `GD25Q64ESIGREBJG`+- `GD25Q64ESIGREBEG`+- `GD25Q64ESIGREBFG`++## CAD (KiCad official)++- Symbol: `GD25Q64ESIGR`+- 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/gd25q64esigr-datasheet.pdf) (62 pp, sha256 `578950858fdf4572`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
