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. Drives the device out of standby and enables the SPI interface; must be held high to deselect the device. Command bytes are latched relative to the CS# falling edge. |+| 2 | SO/IO1 | bidirectional | Serial Data Output in Standard SPI mode (data shifted out on the falling edge of SCLK). Becomes bidirectional data line IO1 during Dual Output Fast Read (3BH) and Dual I/O Fast Read (BBH) commands. |+| 3 | NC | unconnected | No internal connection. Leave floating or tie to ground per system convention. |+| 4 | VSS | power_in | Ground reference for the device. Connect to the system 0 V rail with a low-impedance path. |+| 5 | SI/IO0 | bidirectional | Serial Data Input in Standard SPI mode (data latched on the rising edge of SCLK, MSB first). Becomes bidirectional data line IO0 during Dual Output Fast Read (3BH) and Dual I/O Fast Read (BBH) commands. |+| 6 | SCLK | input | Serial Clock input. Provides the timing for serial input and output; supports SPI modes 0 and 3. Maximum clock of 104 MHz for Fast Read commands. |+| 7 | NC | unconnected | No internal connection. Leave floating or tie to ground per system convention. |+| 8 | VCC | power_in | Device power supply, 1.65 V to 3.6 V. Decouple locally with a 100 nF ceramic capacitor to VSS placed close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Zetta |+| Package | SOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `ZD25WD20CTIGTCTIGT`+- `ZD25WD20CTIGTCTIGR`+- `ZD25WD20CTIGTCTIGY`+- `ZD25WD20CTIGTCTEGT`+- `ZD25WD20CTIGTCTEGR`+- `ZD25WD20CTIGTCTEGY`+- `ZD25WD20CTIGTCO*`+- `ZD25WD20CTIGTCE*`+- `ZD25WD20CTIGTCK*`+- `ZD25WD20CTIGTCJ*`+- `ZD25WD20CTIGTCF*`++## CAD (KiCad official)++- Symbol: `ZD25WD20CTIGT`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Zetta datasheet](docs/zd25wd20ctigt-datasheet.pdf) (40 pp, sha256 `1380bd530052524e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
