Working Principles

AT24C512W-10SI-2.7 utilizes EEPROM technology, which allows for electrically erasing and reprogramming of data. It consists of a grid of memory cells that can be individually addressed for read or write operations. The data is stored in these cells by trapping electrical charges, which represent binary information.

During a write operation, the desired data is sent to the chip through the I2C interface. The data is then stored in the appropriate memory cells by applying specific voltage levels. Reading data involves retrieving the stored charges from the memory cells and converting them back into digital information.
