The X25320S is a 32 Kb Serial SPI EEProm manufactured by Xicor Inc. It is a low-power, serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device. It features a Serial Peripheral Interface (SPI) for communication with a microcontroller or other SPI-compatible devices.

Applications:

• Data storage in embedded systems
• Configuration storage for electronic devices
• Parameter storage for industrial control systems
• Storage of calibration data
• Storing user preferences in consumer electronics

Features:

• 32 Kb (4096 x 8) Serial EEPROM
• SPI Interface (Modes 0,0 & 1,1)
• Low Power Operation
• Self-Timed Write Cycle
• Write Protect Feature
• High Reliability
• 8-Pin Packages

Benefits:

• Non-volatile storage retains data even when power is removed.
• SPI interface simplifies connection to microcontrollers.
• Low power consumption makes it suitable for battery-powered applications.
• Self-timed write cycle simplifies programming and reduces programming time.
