The X2004D25 is a 4K EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Xicor Inc. EEPROMs are non-volatile memory devices that can be electrically erased and reprogrammed, offering flexibility for data storage and updates in various electronic systems. The X2004D25 provides a reliable and cost-effective solution for storing small amounts of data that need to be retained even when power is removed.

Applications

• Data Logging: Storing configuration data and calibration settings.
• Parameter Storage: Holding operating parameters and system configurations.
• Calibration Data: Storing calibration data for sensors and instruments.
• Identification Information: Storing serial numbers and identification codes.
• Security Codes: Storing security codes and access credentials.

Features

• Memory Size: 4K (4096 bits) of non-volatile memory.
• Serial Interface: Utilizes a serial interface (typically SPI or I2C) for communication.
• Low Power Consumption: Designed for low-power operation, suitable for battery-powered applications.
• Write Protection: Offers write protection features to prevent accidental data corruption.
• High Endurance: Supports a high number of write/erase cycles.

Benefits

• Non-Volatile Storage: Retains data even when power is removed.
• Electrical Erasability: Allows for easy data updates and reprogramming.
• Low Power Operation: Suitable for battery-powered devices.
• Reliable Data Storage: Provides reliable storage of critical data.
• Compact Size: Small package allows for integration into space-constrained applications.

Additional Details

The X2004D25 EEPROM is typically accessed through a serial interface, such as SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit). These interfaces allow for easy communication with microcontrollers and other electronic devices. The EEPROM can be used to store a variety of data, including configuration settings, calibration parameters, and identification information. The write protection feature prevents accidental data corruption, while the high endurance ensures that the memory can withstand a large number of write/erase cycles.

Xicor Inc. (now part of Intersil, which is now part of Renesas) was a well-known manufacturer of non-volatile memory devices, including EEPROMs and flash memory. Their products were widely used in various industries, including automotive, industrial, and consumer electronics.
