The X25160 is a CMOS serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Intersil. This device provides a non-volatile storage solution using a Serial Peripheral Interface (SPI). It is typically used to store configuration settings, calibration data, and other important information that needs 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.
• Endurance: 1,000,000 Erase/Write Cycles (typical)

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.

Technical Specifications

The X25160 operates with a supply voltage typically between 4.5V and 5.5V (check datasheet for specific range). The SPI clock frequency is typically up to 10 MHz. It has an operating temperature range of -40°C to +85°C. Data retention is typically specified at over 100 years. The X25160 is commonly available in 8-pin SOIC, PDIP and TSSOP packages.
