W25Q128JVPIQ

Winbond Elec · NOR FLASH · WSON-8-EP(5x6)

W25Q128JVPIQ from Winbond Elec, in a WSON-8-EP(5x6). 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; driving it high deselects the device and puts DO/IO pins in high impedance, and it must track VCC at power-up and power-down.
2 DO (IO1) bidirectional Data Output (Data Input Output 1) used for standard and dual SPI instructions; it is high impedance when the device is deselected.
3 /WP (IO2) bidirectional Write Protect Input (Data Input Output 2) that is active low and is used as IO2 for Quad SPI instructions when QE=1.
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, sampled on the rising edge of CLK.
6 CLK input Serial Clock Input that provides the timing for serial input and output operations.
7 /HOLD (IO3) bidirectional Hold Input (Data Input Output 3) that is active low and pauses the device while selected in standard/dual SPI; it is used as IO3 for Quad SPI when QE=1 and the hold function is then disabled.
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).
