The X25170S is a CMOS serial EEPROM manufactured by Intersil. This device uses a Serial Peripheral Interface (SPI) to communicate with a host microcontroller. It provides non-volatile storage typically used for storing configuration data, user preferences, and calibration settings that need to be retained when power is removed.

Applications

• Consumer Electronics: Storage of user preferences and settings in TVs, DVD players, and other consumer devices.
• Industrial Control Systems: Storing calibration parameters and program settings in industrial equipment.
• Instrumentation: Used in test and measurement equipment for storing calibration data.
• Automotive: Storing configuration data in automotive electronics.
• Medical Devices: Data logging and storage of device parameters in medical equipment.

Features

• SPI Interface: Simple serial communication protocol for easy integration with microcontrollers.
• 16Kb (2048 x 8) Memory Array: Provides a non-volatile storage capacity of 16 kilobits.
• Low-Power Operation: Suitable for battery-powered applications.
• Self-Timed Write Cycle: Simplifies write operations and reduces the need for external timing components.
• Software Write Protection: Prevents accidental overwriting of data.
• High Reliability: Ensures data integrity over extended periods.

Benefits

• Easy Integration: SPI interface simplifies interfacing with microcontrollers.
• Non-Volatile Storage: Retains data even when power is removed.
• Low Power Consumption: Suitable for battery-powered applications.
• Reliable Data Storage: Ensures data integrity over a long lifespan.
• Small Footprint: Available in small packages for space-constrained applications.
