Working Principles

The AT24C128W-10SC-1.8 utilizes an I2C-compatible interface for communication with the host device. It employs a combination of floating gate transistors and control circuitry to store and retrieve data. When data is written, charge is trapped in the floating gate, altering the transistor's behavior. This trapped charge represents the stored information. During read operations, the transistor's behavior is determined by the presence or absence of charge in the floating gate, allowing the retrieval of stored data.
