Working Principles

The AT24C04D-MAHM-T utilizes electrically controlled floating gate transistors to store data. When a specific voltage is applied, charges are trapped in the floating gate, representing either a "0" or a "1" bit. These charges can be erased by applying a higher voltage, allowing new data to be written.

Detailed Application Field Plans

The AT24C04D-MAHM-T finds applications in various fields, including:

1. Microcontrollers: Used for storing configuration settings, calibration data, and program code.
2. Computers: Employed in BIOS chips for storing system information and firmware updates.
3. Consumer electronics: Utilized in devices like smart TVs, set-top boxes, and digital cameras for storing user preferences and settings.
