Working Principles

The 25LC160CT-I/MS utilizes EEPROM technology to store and retrieve data. It employs a floating gate transistor structure that can be electrically programmed and erased. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. These charges can be removed during an erase operation, allowing the transistor to return to its original state.

Detailed Application Field Plans

The 25LC160CT-I/MS finds applications in various electronic devices that require non-volatile storage, such as: - Consumer electronics (e.g., smartwatches, digital cameras) - Automotive systems (e.g., infotainment systems, engine control units) - Industrial equipment (e.g., data loggers, control systems) - Medical devices (e.g., patient monitoring systems, diagnostic equipment)
