Working Principles

The AT49F512-55JU utilizes Flash memory technology, which is based on floating-gate transistors. It stores data by trapping electric charges within the floating gate, which alters the transistor's behavior. This trapped charge can be retained for an extended period, allowing non-volatile storage of data.

During read operations, the stored charge is measured to determine the logic state of each memory cell. Write operations involve applying higher voltages to the appropriate pins to modify the charge within the floating gate.

Detailed Application Field Plans

The AT49F512-55JU finds applications in various electronic systems, including but not limited to: - Embedded systems - Consumer electronics - Automotive electronics - Industrial control systems - Communication devices
