The X25165S8-2.7 is a 16Kb Serial SPI Bus EEPROM manufactured by Xicor Inc. (now Intersil/Renesas). It's a non-volatile memory device used for storing configuration data, calibration parameters, and other persistent information.

Applications:

• Data storage
• Configuration storage
• Calibration parameter storage
• Serial presence detect (SPD)
• Embedded systems

Features:

• 16Kb (2048 x 8) memory organization
• SPI serial interface
• Self-timed write cycle
• Low power consumption
• Write protect feature
• 8-pin SOIC package
• Operating Voltage: 2.7V

Benefits:

• Non-volatile storage: Data is retained even when power is removed.
• Simplified interface: SPI interface requires minimal I/O pins.
• Easy programming: Self-timed write cycle simplifies the write process.
• Low power operation: Conserves energy in battery-powered devices.
• Data protection: Write protect feature prevents accidental data corruption.

Additional Details:

The X25165S8-2.7 operates from a 2.7V power supply. It supports standard SPI clock rates. The data retention is typically specified for many years. The SOIC package is industry-standard and compatible with automated assembly processes. The part includes features such as software write protection and hardware write protection via the WP pin.
