The X28C513J-12 is a 512K (64K x 8) CMOS EEPROM manufactured by Xicor (later acquired by Intersil, and then Renesas). It's a non-volatile memory device that can be electrically erased and reprogrammed. The 'J-12' indicates a specific speed grade, in this case, a 120ns access time.

Applications

• BIOS storage in computer systems
• Firmware storage in embedded systems
• Data logging
• Programmable logic controllers (PLCs)
• Industrial control equipment
• Network equipment

Features

• 512K (64K x 8) bit organization.
• Fast access time (120ns).
• Electrically Erasable and Programmable Read-Only Memory (EEPROM).
• JEDEC standard pinout.
• Low power CMOS technology.
• Automatic page write operation.
• Data protection circuitry.

Benefits

• Non-volatile data storage, retaining data even when power is removed.
• In-system programmability, allowing firmware updates without removing the device.
• Fast access time for quick data retrieval.
• Low power consumption for energy-efficient applications.
• Standard pinout for easy integration into existing systems.

Additional Details

The X28C513J-12 typically operates from a single 5V power supply. It supports byte-wide and page-mode writes. The endurance rating, representing the number of erase/write cycles the device can withstand, is typically 10,000 cycles. It is often found in DIP (Dual In-line Package) format for easy prototyping and through-hole mounting. The device is susceptible to ESD (Electrostatic Discharge), so appropriate handling precautions are required.
