Working Principles

The FT24C04A-KTR-T utilizes an electrically erasable floating-gate transistor technology. Data is stored in memory cells by trapping charges on the floating gate, which alters the threshold voltage of the transistor. This change in threshold voltage represents the stored data bit (0 or 1). The stored data can be modified by applying appropriate voltage levels to the control gates and drain terminals of the memory cells.

Detailed Application Field Plans

The FT24C04A-KTR-T finds applications in various fields, including:

1. Embedded systems: Used for storing configuration data, firmware updates, and user settings in microcontrollers and system-on-chips.
2. Consumer electronics: Employed in devices like smart TVs, set-top boxes, and audio systems for storing user preferences, channel lists, and other non-volatile data.
3. Industrial automation: Utilized for storing calibration data, sensor configurations, and production parameters in programmable logic controllers (PLCs) and industrial control systems.
4. Automotive electronics: Integrated into automotive modules for storing critical data, such as mileage, vehicle settings, and diagnostic information.

Detailed and Complete Alternative Models
