Working Principles

The 25LC080C-I/SN operates based on the principles of EEPROM (Electrically Erasable Programmable Read-Only Memory). It uses a floating gate transistor structure to store and retrieve data. The SPI interface allows for easy communication with a microcontroller or other devices.

When writing data, the chip performs self-timed erase and write cycles. The data is stored in non-volatile memory cells that retain their state even when power is removed. The hardware write protection feature prevents accidental writes to the memory.

During operation, the chip can be enabled or disabled using the Chip Select (CS) pin. The Serial Clock (SCK) provides the timing for data transfer, while the Serial Data Input (SI) and Serial Data Output (SO) pins handle the data exchange between the chip and the master device.
