# 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). |
