Working Principles

The 25LC010A-H/SN utilizes EEPROM technology to store and retrieve data. It employs a floating gate transistor structure that allows for the trapping and releasing of electric charge, representing binary information (0s and 1s). The SPI interface facilitates communication between the chip and external devices, enabling read and write operations.

During a write operation, the chip receives data serially through the SI pin and stores it in the memory array. The CS pin is used to select the chip for communication, while the SCK pin provides the clock signal for synchronization. The WP pin can be used to enable or disable write protection.

During a read operation, the chip retrieves stored data from the memory array and sends it serially through the SO pin. The HOLD pin can be used to pause ongoing operations without losing data.
