Working Principles

The AT24C164-10PI-2.5 utilizes electrically erasable programmable read-only memory (EEPROM) technology. It stores data in a grid of memory cells that can be individually addressed and written to or read from using the I2C serial interface. The data is retained even when power is disconnected due to the non-volatile nature of EEPROM.

During write operations, the IC accepts data input through the SDA pin and writes it to the specified memory location. Reading data involves sending a read command followed by the memory address, and the IC outputs the requested data through the SDA pin.
