The Intersil X24C01ST1 is a 1Kbit CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory) device. Organized as 128 x 8 bits, it uses a 2-wire serial interface (I2C) for communication. It provides non-volatile storage for a variety of applications needing small amounts of persistent data. The 'ST1' likely signifies a specific packaging option and/or temperature grade.

Applications:

• Consumer Electronics: Used to store user preferences, settings, and configuration data in televisions, set-top boxes, DVD players, and remote controls.
• Industrial Control: Employed in industrial sensors, meters, and control systems for storing calibration constants, device identification, and configuration parameters.
• Instrumentation: Integrated into test and measurement equipment for storing calibration data, instrument settings, and serial numbers.
• Medical Devices: Non-volatile storage for device settings, calibration information, and patient-related data in portable medical devices.
• Automotive Electronics: Storage of configuration settings, diagnostic codes, and vehicle identification information in automotive control modules.

Features:

• 1Kbit (128 x 8) EEPROM: Provides 1024 bits of non-volatile storage.
