The X28C512D-15 is a 512K (64K x 8) EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Xicor Inc. This non-volatile memory device allows for in-system electrical erasure and reprogramming, making it suitable for applications requiring frequent updates or data storage without power.

Applications:

• Data Logging: Used in devices that need to store data persistently, such as industrial sensors and data acquisition systems.
• Firmware Storage: Stores firmware code for embedded systems and microcontrollers, allowing for easy updates.
• Configuration Settings: Stores configuration parameters and settings for various electronic devices.
• Calibration Data: Used in instruments and devices that require calibration data to be stored and retrieved.

Features:

• Electrically Erasable and Programmable: Allows for in-system erasure and reprogramming without removing the chip.
• 512K (64K x 8) Memory Organization: Provides a storage capacity of 512 kilobits organized as 64K bytes.
• Fast Access Time: Offers a fast read access time for quick data retrieval. The '-15' in the part number indicates a 150ns access time.
• Automatic Page Write: Simplifies the writing process and reduces the number of write cycles.
• Data Polling: Allows the system to monitor the write status and determine when the write operation is complete.
• Low Power Consumption: Consumes minimal power during operation and standby.

Benefits:

• In-System Reprogrammability: Enables convenient firmware updates and configuration changes without requiring chip removal.
• Non-Volatile Storage: Retains data even when power is removed, ensuring data integrity.
• High Endurance: Withstands a large number of erase/write cycles, providing long-term reliability.
• Fast Access Time: Allows for quick data retrieval, improving system performance.
• Simplified Programming: Automatic page write and data polling features simplify the programming process.

Technical Specifications:

The X28C512D-15 operates on a single 5V power supply. It has a typical endurance of 10,000 erase/write cycles per byte. The access time is 150ns, as indicated by the -15 suffix in the part number. It's available in a DIP package. Refer to the Xicor datasheet for detailed specifications on voltage levels, timing characteristics, and programming procedures.

The X28C512D-15 EEPROM is a reliable and versatile non-volatile memory solution for a wide range of applications. Its in-system reprogrammability, high endurance, and fast access time make it an ideal choice for storing firmware, configuration settings, and other critical data.
