Working Principles

The AT49LV001T-90JI utilizes flash EEPROM technology to store and retrieve digital information. It consists of an array of floating-gate transistors that can be electrically programmed and erased. When data is written, charges are trapped in the floating gate, altering the transistor's threshold voltage. This change in threshold voltage allows the stored data to be retained even when power is removed. The device can be accessed and manipulated through various control signals.

Detailed Application Field Plans

The AT49LV001T-90JI finds applications in a wide range of electronic systems, including but not limited to: - Embedded systems - Consumer electronics - Automotive electronics - Industrial control systems - Communication devices
