The GT24C256A-2GLI-TR is a 256 Kbit (32KB) Serial EEPROM utilizing the I2C (Two-Wire) serial interface, manufactured by Giantec. It is a non-volatile memory device used to store configuration data, user preferences, or other data that needs to be retained when power is removed. The device is commonly used in a wide range of applications due to its ease of use, low power consumption, and small footprint.

Applications

• Consumer Electronics: Used in TVs, DVD players, set-top boxes to store user settings and firmware updates.
• Industrial Control Systems: Employed in programmable logic controllers (PLCs), sensors, and data loggers to store configuration parameters and calibration data.
• Automotive Electronics: Utilized in car radios, navigation systems, and engine control units (ECUs) for storing system settings and diagnostic information.
• Medical Devices: Found in patient monitoring equipment and diagnostic tools for storing calibration data and patient information.
• Networking Equipment: Used in routers, switches, and modems to store configuration files and firmware.
