W25Q32JV in a circuit

A physical eight-lead package and a compatible 3.3 V controller.

W25Q32JV eight-pin circuit with four colored SPI signals,3.3V supply,100nF bypass and10k pullups. Ahost transmits9F000000 andexpects EF4016 identification.
Standard SPI identification example. The illustrated bytes are expected values, not a live measurement.

Connect it, step by step

Follow the component values and pin connections

Power and define idle state

Bypass VCC locally and keep CS HIGH through power-up.

Send the identification opcode

At 1 MHz mode0, transfer 9F and three dummy bytes under one CS LOW interval.

Read and deselect

Receive EF4016 after the opcode response, then raise CS.
