The X28C513JI-20 is a 512K EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Xicor Inc. It's a non-volatile memory, which means it retains stored data even when power is removed. This memory chip is designed for applications requiring reliable data storage and in-system programmability.

Applications:

• Embedded Systems: Stores configuration data, boot code, and application software in various embedded systems.
• Industrial Control: Used in programmable logic controllers (PLCs), data acquisition systems, and other industrial automation equipment.
• Telecommunications: Stores configuration parameters and firmware updates in communication devices such as routers and switches.
• Automotive Electronics: Integrated into engine control units (ECUs), instrument clusters, and other automotive electronic modules.
• Medical Equipment: Stores calibration data and operating parameters in medical devices.

Features:

• 512K (64K x 8) Memory Organization: Provides a storage capacity of 512 kilobits, organized as 65,536 bytes.
• Fast Access Time: Offers a fast read access time, typically around 200ns for the X28C513JI-20 variant.
• In-System Programmability: Allows the device to be programmed and erased while still installed in the target system.
• Low Power Consumption: Designed for low-power operation, making it suitable for battery-powered applications.
• Automatic Page Write Operation: Supports automatic page write for faster programming.

Benefits:

• Non-Volatile Data Storage: Retains data even when power is off, ensuring data integrity.
• Flexibility: Allows for easy updates and changes to stored data without removing the device from the system.
• Reliability: Provides reliable data storage and retrieval over a wide range of operating conditions.
• Simplified System Design: Simplifies system design by eliminating the need for external programming equipment.
• Cost-Effective Solution: Offers a cost-effective solution for non-volatile memory requirements.

Additional Details:

The X28C513JI-20 operates on a single 5V power supply. The device features endurance of typically 10,000 erase/write cycles per byte. It also includes features such as data polling and toggle bit for end-of-write detection. Further details on power consumption, operating temperature range, and package type (likely a JEDEC standard) can be found in the product datasheet. The -20 suffix in the part number indicates a specific access time of 200ns.
