W25X05CLSNIG from Winbond Elec, in a SOIC-8. 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 | SPI Chip Select input, active low. When high, DO/IO0/IO1 pins are high impedance and the device is in standby. Must track VCC at power-up; a pull-up resistor may be used. |
| 2 | DO (IO1) | bidirectional | Serial Data Output for Standard SPI (unidirectional output on falling edge of CLK). Becomes bidirectional I/O pin IO1 during Dual SPI Fast Read Dual Output (3Bh) and Fast Read Dual I/O (BBh) instructions. |
| 3 | /WP | input | Write Protect input, active low. In conjunction with the Status Register SRP, TB, BP1 and BP0 bits, hardware-protects a portion or the entire memory array from write/erase and locks the Status Register. |
| 4 | GND | power_in | Ground reference (0V) for VCC (2.3V-3.6V supply). |
| 5 | DI (IO0) | bidirectional | Serial Data Input for Standard SPI (unidirectional input latched on rising edge of CLK for instructions/addresses/data). Becomes bidirectional I/O pin IO0 during Dual SPI Fast Read Dual Output (3Bh) and Fast Read Dual I/O (BBh) instructions. |
| 6 | CLK | input | SPI Serial Clock input, up to 104 MHz. Provides timing for serial input (rising edge) and output (falling edge) operations. Supports SPI Mode 0 (0,0) and Mode 3 (1,1). |
| 7 | /HOLD | input | Hold input, active low. When asserted with /CS low, pauses device operation: DO becomes high-impedance and DI/CLK are ignored, allowing the SPI bus to be shared without losing device state. |
| 8 | VCC | power_in | Power supply input, 2.3V to 3.6V (2.5V / 3V / 3.3V nominal). Typical 1 mA active current, <1 uA power-down. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 591 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
