Working Principles

The W25Q128FVCIG is based on the Serial Peripheral Interface (SPI) protocol. It utilizes a combination of floating gate and tunnel oxide technology to store digital information. When data is written, charges are trapped in the floating gate, altering the threshold voltage of the memory cell. This change in voltage determines the stored data. During read operations, the threshold voltage is measured to retrieve the stored information.

Detailed Application Field Plans

The W25Q128FVCIG is widely used in various electronic devices that require non-volatile memory for data storage and retrieval. Some common application fields include:

  1. Consumer Electronics: Smartphones, tablets, digital cameras, gaming consoles
