Working Principles

The AT49LH00B4-33JX-T utilizes flash memory technology to store data. It consists of a grid of memory cells, where each cell can store a bit of information. These cells are organized into pages and blocks for efficient read and write operations. When data is written, an electrical charge is applied to the memory cell, altering its state. To read the stored data, the cell's state is detected by sensing the electrical current flowing through it.

Detailed Application Field Plans

The AT49LH00B4-33JX-T finds applications in various fields, including: 1. Microcontrollers: Used for program storage in microcontroller-based systems. 2. Embedded Systems: Provides non-volatile storage for firmware and configuration data in embedded systems. 3. Consumer Electronics: Used in devices like digital cameras, set-top boxes, and portable media players for data storage.
