Working Principles

The AT24C04D-PUM chip utilizes electrically erasable programmable read-only memory (EEPROM) technology. It consists of a grid of memory cells that can be individually programmed or erased using electrical signals. When data is written to the chip, it is stored in the memory cells as electrical charges. These charges can be read back as data when required. The chip's internal circuitry manages the reading, writing, and erasing operations.
