Working Principles

The NM93C06EM8 is a non-volatile memory IC that utilizes EEPROM (Electrically Erasable Programmable Read-Only Memory) technology. It stores data by electrically charging and discharging specific memory cells within the chip. The stored data can be read, modified, or erased using the serial interface provided.

During operation, the microcontroller communicates with the NM93C06EM8 through the SPI interface. The microcontroller sends commands and data to the IC via the SI pin, while receiving data from the SO pin. The /CS pin is used to select the device, and the SCK pin synchronizes the data transfer between the microcontroller and the IC.
