The X28C010KM-25 is a 1 Megabit (128K x 8) CMOS EEPROM manufactured by Xicor Inc. (later acquired by Intersil, then Renesas). It's a non-volatile memory device that can be electrically erased and reprogrammed. It's commonly used for storing firmware, configuration data, and other data that needs to be retained even when power is removed.

Applications:

• Firmware storage
• Configuration data storage
• Programmable logic devices (PLDs)
• Data logging
• Industrial control systems
• Embedded systems

Features:

• 1 Megabit (128K x 8) capacity
• CMOS technology for low power consumption
• Electrically erasable and programmable (EEPROM)
• Fast access time (250ns)
• Page mode write operation
• Automatic page write operation
• Data polling for end-of-write detection
• JEDEC standard byte-wide pinout

Benefits:

• Non-volatile data storage
• In-system programmability
• Low power consumption
• Fast access time
• Simplified write operations with page mode

Additional Details:

The "-25" in the part number indicates an access time of 250ns. The EEPROM technology allows for a limited number of erase/write cycles, typically in the range of 10,000 to 100,000 cycles per byte. Page mode write operation allows multiple bytes to be written in a single operation, improving write performance. Automatic page write operation simplifies the write process. Data polling can be used to determine when a write operation is complete, allowing the system to continue with other tasks. The JEDEC standard byte-wide pinout ensures compatibility with other memory devices. The Xicor (now Renesas) datasheet provides detailed information on programming algorithms, timing diagrams, and electrical characteristics.
