Working Principles

The AT24C01A-10PI-1.8 IC is based on EEPROM technology, which allows for electrically erasing and reprogramming data. It utilizes a floating gate transistor structure to store charge, representing binary information. The stored data can be accessed and modified using the I2C interface.

During a write operation, the IC applies a high voltage to the selected memory cell, causing electrons to tunnel through an insulating layer onto the floating gate. This process traps the charge, altering the cell's threshold voltage and storing the desired data. Reading data involves applying appropriate voltages and sensing the resulting current flow to determine the stored charge.
