Working Principles

The AT24C256W-10SC-1.8 utilizes electrically erasable programmable read-only memory technology. It consists of an array of memory cells that can be individually programmed or erased using electrical signals. The stored data is retained even when power is removed, making it non-volatile.

The chip communicates with the host device through a serial interface, using the SDA and SCL pins for data transfer. The address pins (A0, A1, A2) are used to select the specific memory location for read or write operations. The WP pin provides hardware write protection, while software commands can be used to enable or disable write protection.
