Working Principles

AT25080BY6-YH-T utilizes electrically controlled floating gate transistors to store data. When a byte is written, an electrical charge is trapped in the floating gate, representing a logical "1." Erasing the byte involves removing the charge, returning it to a logical "0." The state of each memory cell is determined by the presence or absence of charge in its floating gate.

Application Field Plans

AT25080BY6-YH-T finds applications in various fields, including: - Automotive electronics: Used for storing configuration data and event logs. - Industrial automation: Stores calibration data and system parameters. - Consumer electronics: Used in smart TVs, set-top boxes, and gaming consoles for firmware storage. - Medical devices: Stores patient data, device settings, and diagnostic information.
