Working Principles

The NM93C13N is a non-volatile memory IC that utilizes EEPROM (Electrically Erasable Programmable Read-Only Memory) technology. It stores digital information in a series of memory cells, which can be electrically programmed and erased. The device communicates with a microcontroller or other devices through the I2C bus, allowing for easy integration into various systems.

During operation, the chip select (CS) pin enables the device, and the serial clock (SCK) synchronizes the data transfer. Data can be written to the memory by providing the appropriate address and data inputs. Similarly, data can be read from the memory by specifying the desired address and retrieving the corresponding data output.

The write protect (WP) pin provides an additional layer of security by preventing accidental modification of stored data. The NM93C13N operates within a specified voltage range and temperature range, ensuring reliable performance in various environments.
