Working Principles

The 25LC160B-I/PG utilizes an electrically erasable programmable read-only memory (EEPROM) technology. It stores data by trapping charges within a floating gate transistor structure. To write data, a high voltage is applied to the gate, allowing electrons to tunnel onto the floating gate. Erasing data involves removing these trapped charges using ultraviolet light or electrical methods.

During normal operation, the chip communicates with a microcontroller or other digital system using the Serial Peripheral Interface (SPI). This interface allows the transfer of data between the chip and the controlling device.
