Working Principles

The AT93C46-10TU-2.7 utilizes a floating gate transistor technology to store data in its non-volatile memory cells. When data needs to be written, a voltage is applied to the appropriate memory cell, causing electrons to tunnel onto or off the floating gate. This alters the threshold voltage of the transistor, representing a binary 0 or 1. During read operations, the stored charge is sensed to determine the stored data.

Detailed Application Field Plans

The AT93C46-10TU-2.7 can be used in various applications, including: 1. Consumer Electronics: Used for storing configuration settings, calibration data, or user preferences in devices like TVs, set-top boxes, and audio systems. 2. Automotive: Employed in automotive electronics for storing vehicle-specific data, such as mileage, service history, or security information. 3. Industrial Control Systems: Utilized in industrial automation and control systems for storing critical parameters, device configurations, or production data. 4. Medical Devices: Integrated into medical equipment to store patient data, device settings, or diagnostic information. 5. Smart Cards: Incorporated into smart cards for secure storage of personal identification, financial data, or access control information.
