Working Principles

The 24LC65-I/SM utilizes an electrically controlled floating gate to store and retrieve data. When data is written, a voltage is applied to the gate, causing electrons to tunnel through a thin oxide layer and become trapped in the floating gate. These trapped charges represent the stored data. During read operations, the charge level in the floating gate is measured to determine the stored data.

Detailed Application Field Plans

The 24LC65-I/SM finds applications in various electronic devices and systems, including but not limited to: - Consumer electronics (e.g., smart TVs, set-top boxes) - Automotive electronics (e.g., infotainment systems, engine control units) - Industrial automation (e.g., programmable logic controllers, data loggers) - Medical devices (e.g., patient monitoring systems, diagnostic equipment) - Internet of Things (IoT) devices (e.g., smart home appliances, wearable devices)
