W25N04KVZEIR

WINBOND · Global Sourcing Parts · WSON-8(6x8)

W25N04KVZEIR from WINBOND, in a WSON-8(6x8). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 /CS input Chip Select input: when high the device is deselected and the DO/IO pins are high impedance, and /CS must track the VCC supply level at power-up and power-down.
2 DO (IO1) bidirectional Data Output (Data Input Output 1), used for Standard and Dual SPI instructions and as IO1 for Quad SPI operation.
3 /WP (IO2) bidirectional Write Protect input, active low, which controls Status Register-1 write protection depending on WP-E and also functions as IO2 for Quad SPI; /WP is only available for Standard/Dual SPI as a control function.
4 GND power_in Ground reference for the device.
5 DI (IO0) bidirectional Data Input (Data Input Output 0), used for Standard and Dual SPI instructions and as IO0 for Quad SPI; data is latched on the rising edge of CLK in Standard SPI.
6 CLK input Serial Clock input that provides the timing for serial input and output operations, with up to 104MHz SPI clock frequency supported.
7 /HOLD (IO3) bidirectional Hold input, active low, which pauses device operation while selected in Standard/Dual SPI and becomes IO3 for Quad SPI operations; it must be driven high or pulled up to avoid floating.
8 VCC power_in Power supply; the device operates on a single 2.7V to 3.6V supply.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: W25N04KVZEIR
  • Footprint: Package_SON:WSON-8-1EP_8x6mm_P1.27mm_EP3.4x4.3mm
  • 3D model: WSON-8(6x8), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.75 mm nominal WSON height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: w25n04kvzeir-etched.step / w25n04kvzeir-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); w25n04kvzeir.step / w25n04kvzeir.glb are the bare package body.
