- Interface: SPI (standard SPI; some variants support dual/quad I/O in other models).
- Addressing: 3-byte addressing suitable for up to 16 MB.
- Operations: Page program, sector/block erase, and chip erase; supports read, write protection and security features; power-down modes.
- Packaging: 8-pin device (SIM suffix indicates package type).
Common uses:
- Storing firmware/bootloaders, parameter data, and logs in microcontroller-based designs.
- Firmware updates and data storage in consumer, industrial, and automotive applications.
For exact electrical specs, timing, supported commands, and voltage ranges, refer to the Winbond W25Q32JW(S) datasheet.
