Working Principles

The AT49BV1614AT-90TI utilizes flash memory technology to store data. It consists of a grid of memory cells that can be electrically programmed and erased. When data is written, an electrical charge is applied to the memory cell, altering its state. To erase data, the charge is removed from the cell. The stored data can be accessed by sending appropriate address signals and reading the corresponding data from the memory cells.

Detailed Application Field Plans

The AT49BV1614AT-90TI finds applications in various electronic systems, including but not limited to: - Embedded systems - Consumer electronics - Automotive electronics - Industrial control systems - Communication devices
