Working Principles

The AT49BV001NT-12TC utilizes flash memory technology to store and retrieve digital information. It consists of a grid of memory cells, each capable of storing a single bit of data. These cells are organized into rows and columns, with each row representing a memory address.

To write data, the device applies a high voltage to the selected memory cell, causing electrons to be trapped in a floating gate within the cell. This trapped charge represents the stored data. To read data, the device measures the electrical state of the memory cell, determining whether it is programmed or erased.

Detailed Application Field Plans

The AT49BV001NT-12TC finds applications in various electronic systems, including but not limited to: - Embedded systems - Consumer electronics - Automotive electronics - Industrial control systems - Communication devices

Its ability to retain data without power and its wide temperature range make it suitable for use in harsh environments and critical applications.
