The X24C04 is a 4 Kb CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory) from Xicor Inc. It is organized as 512 x 8 bits and operates on a single 5V power supply. This device is designed for applications requiring non-volatile storage of data, such as configuration settings, calibration parameters, and serial numbers.

Applications:

• Storage of configuration data in electronic devices
• Calibration parameter storage in instrumentation
• Serial number storage in various systems
• Data logging applications
• Consumer electronics

Features:

• 4 Kb (512 x 8) EEPROM
• Low voltage operation (5V)
• Self-timed write cycle
• Automatic erase-before-write operation
• Write protect feature for data security
• Serial interface for easy communication with microcontrollers
• Low power consumption
• High reliability and endurance

Benefits:

• Non-volatile storage ensures data retention even when power is removed.
• Simple serial interface reduces the number of I/O pins required from the microcontroller.
• Write protect feature prevents accidental data corruption.
• Low power consumption is suitable for battery-powered applications.
• High endurance ensures long-term reliability in write-intensive applications.
• Self-timed write cycle simplifies the write operation and reduces software overhead.

Additional Details:

The X24C04 utilizes a two-wire serial interface, compatible with the I2C protocol, enabling straightforward communication with microcontrollers. The device supports page write operations, allowing multiple bytes to be written in a single write cycle, improving write performance. The EEPROM offers a typical endurance of 1 million erase/write cycles per byte, and a data retention of 100 years, providing robust non-volatile storage. The device is available in various packages, including DIP and SOIC.
