Working Principles

AT49F002-90VC utilizes a floating gate transistor technology to store data. It employs a combination of electrical charges to represent binary values (0s and 1s). During programming, charges are injected into the floating gate, altering its electrical characteristics. Erasing is achieved by removing these charges from the floating gate. The presence or absence of charges determines the stored data.

Detailed Application Field Plans

AT49F002-90VC finds applications in various electronic devices, including but not limited to: - Personal computers - Laptops and notebooks - Smartphones and tablets - Digital cameras - Gaming consoles - Industrial control systems - Automotive electronics
