Working Principles

The NM24C16EN is an electrically erasable programmable read-only memory (EEPROM) IC. It stores data using a floating gate transistor structure that can be electrically programmed and erased. The IC uses a serial interface to communicate with the microcontroller or host system. Data can be written, read, and erased at the byte level.

During a write operation, the data to be stored is sent serially to the IC along with the appropriate control signals. The IC internally manages the erase and write cycles, ensuring data integrity and reliability. The stored data remains non-volatile, meaning it is retained even when power is removed.
