Working Principles

The 11AA020T-I/CS16K is an EEPROM IC that stores data using electrically isolated floating-gate transistors. It utilizes the I2C interface for communication with the microcontroller or host device. The data can be written, read, and erased electronically, making it non-volatile and capable of retaining information even when power is disconnected.

Detailed Application Field Plans

• Embedded Systems: Used for storing configuration settings, calibration data, and firmware updates in various embedded systems such as IoT devices, industrial control systems, and consumer electronics.
• Automotive Electronics: Employed in automotive applications for storing critical data like vehicle identification numbers (VIN), mileage, and fault codes.
• Smart Cards: Integrated into smart cards for secure storage of personal information, financial data, and access control credentials.
• Medical Devices: Utilized in medical devices for storing patient records, treatment history, and device-specific configurations.
