Working Principles

The AT49F002ANT-55TU utilizes flash memory technology, which is based on the principle of trapping electrical charges in a floating gate. These trapped charges represent binary data (0 or 1). The device uses a combination of transistors and capacitors to store and retrieve data.

During write operations, an electric charge is applied to the control gate, allowing electrons to tunnel through the insulating layer and become trapped in the floating gate. This process alters the threshold voltage of the memory cell, representing the desired data value.

During read operations, the stored charge is measured by applying a voltage to the control gate and sensing the resulting current flow. The magnitude of the current determines the stored data value.

Detailed Application Field Plans

The AT49F002ANT-55TU can be used in various applications, including but not limited to: - Embedded systems - Consumer electronics - Automotive electronics - Industrial control systems - Communication devices
