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). Drive low to select the device and enable command/data transfer; drive high to deselect and place SO in High-Z. |+| 2 | SO/IO1 | bidirectional | Serial Data Output in standard SPI mode; becomes bidirectional data line IO1 during Dual SPI operations (Dual Output Fast Read 3BH, Dual I/O Fast Read BBH, DREMS 92H). |+| 3 | NC | unconnected | No connection. May be left floating or tied to ground. |+| 4 | VSS | power_in | Ground reference for all supply and signal pins. |+| 5 | SI/IO0 | bidirectional | Serial Data Input in standard SPI mode; becomes bidirectional data line IO0 during Dual SPI operations. All commands, addresses, and data-in are shifted in MSB-first on the rising edge of SCLK. |+| 6 | SCLK | input | Serial Clock input. Supports SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1). Input data is latched on the rising edge and output data is shifted on the falling edge. Max 104MHz single-I/O fast read. |+| 7 | NC | unconnected | No connection. May be left floating or tied to ground. |+| 8 | VCC | power_in | Power supply input, 1.65V to 3.6V. Typical currents: 1.3mA active read at 33MHz, 3.2mA active program/erase, 0.5uA standby, 0.3uA deep power-down. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Zetta |+| Package | USON-8(2x3) |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `ZD25WD20CEIGR`+- `ZD25WD20CEIGREIGT`+- `ZD25WD20CEIGREIGY`+- `ZD25WD20CEIGREEGR`+- `ZD25WD20CEIGRTIGR`+- `ZD25WD20CEIGRTEGR`+- `ZD25WD20CEIGRTIGT`+- `ZD25WD20CEIGROIGR`+- `ZD25WD20CEIGROEGR`+- `ZD25WD20CEIGRKIGR`+- `ZD25WD20CEIGRKEGR`+- `ZD25WD20CEIGRJIGR`+- `ZD25WD20CEIGRJEGR`+- `ZD25WD20CEIGRFIGR`+- `ZD25WD20CEIGRFEGR`++## CAD (KiCad official)++- Symbol: `ZD25WD20CEIGR`+- Footprint: `Package_SON:Winbond_USON-8-1EP_3x2mm_P0.5mm_EP0.2x1.6mm`+- 3D model: USON-8(2x3) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Zetta datasheet](docs/zd25wd20ceigr-datasheet.pdf) (40 pp, sha256 `114863a3cfb6032a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
