The X25170S8I-2.5 is a serial EEPROM manufactured by Intersil, designed for use in industrial applications. This device utilizes the SPI (Serial Peripheral Interface) protocol for communication and operates at a low voltage of 2.5V. The 'I' in the part number indicates an industrial temperature range, making it suitable for harsh environments. It provides non-volatile storage for configuration data, calibration parameters, and other critical information that must be retained when power is off.

Applications

• Industrial Control Systems: Used in programmable logic controllers (PLCs), motor drives, and process control equipment for storing program code, calibration parameters, and system logs.
• Industrial Automation: Integrated into robotic systems, automated assembly lines, and other industrial automation equipment for storing configuration data and operational parameters.
• Data Logging: Employed in industrial data loggers for storing sensor readings and other data over extended periods.
• Remote Monitoring: Utilized in remote monitoring systems for storing configuration settings and sensor data in challenging environments.
• Automotive Applications: Suitable for certain automotive applications requiring reliable data storage over a wide temperature range.
