Working Principles

AT25256T2-10TI utilizes electrically controlled floating gate transistors to store and retrieve data. When data is written, an electrical charge is trapped in the floating gate, altering the transistor's behavior. This charge can be removed during erasure, allowing the transistor to return to its original state. The stored data can be accessed by applying appropriate voltages to the memory cells.

Detailed Application Field Plans

AT25256T2-10TI finds applications in various fields, including: 1. Automotive electronics: Used for storing vehicle configuration data, firmware updates, and event logging. 2. Industrial automation: Enables storage of calibration data, configuration settings, and production records. 3. Consumer electronics: Utilized for storing user preferences, firmware updates, and device-specific data.

Detailed and Complete Alternative Models

1. AT25256A-10PU: Similar to AT25256T2-10TI but in a DIP (Dual Inline Package) form factor.
