Working Principles

The GD25LQ16CSIGR utilizes the Serial Peripheral Interface (SPI) protocol for communication with the host device. It stores data in a non-volatile manner using floating-gate transistors. When data is written, charges are trapped in the floating gate, altering the transistor's behavior and storing the information. During read operations, the trapped charges are detected, allowing retrieval of the stored data.

Application Field Plans

The GD25LQ16CSIGR is widely used in various electronic devices that require non-volatile data storage. Some of its application fields include:

1. Smartphones and tablets
2. Digital cameras
3. Portable media players
4. Automotive electronics
5. Industrial control systems
