Working Principles

The CAT24C64YI-GT3JN utilizes electrically controlled floating gate transistors to store data. When data is written, charges are trapped in the floating gate, altering the transistor's threshold voltage. This change in threshold voltage determines the stored data value. During read operations, the threshold voltage is measured to retrieve the stored data.

Detailed Application Field Plans

The CAT24C64YI-GT3JN finds applications in various fields, including:

1. Automotive: Used for storing configuration data, calibration parameters, and event logs in automotive electronic control units (ECUs).
2. Industrial Automation: Employed in programmable logic controllers (PLCs) for storing program code, configuration settings, and historical data.
3. Consumer Electronics: Utilized in devices like smart TVs, set-top boxes, and gaming consoles for storing user preferences, firmware updates, and application data.
4. Medical Devices: Used for storing patient data, device configurations, and event logs in medical equipment such as infusion pumps and patient monitors.
