Working Principles

The M24256-WMW6 utilizes electrically erasable programmable read-only memory (EEPROM) technology. It stores data in a grid of memory cells, which can be individually programmed or erased using electrical signals. The I2C interface allows for easy communication between the IC and the controlling device.

When data needs to be written, the appropriate address is selected, and the desired information is sent through the serial data input (SDA) pin. The data is then stored in the specified memory location. Reading data involves selecting the desired address and retrieving the stored information from the memory cells.
