The CAT28C64BT13-90T is a 64-kb Parallel CMOS EEPROM manufactured by Catalyst Semiconductor. This EEPROM provides non-volatile memory storage with a parallel interface, designed for applications needing fast access times and reliable data retention. As an older technology, it uses a parallel interface rather than the more modern serial interfaces.

Applications:

• Legacy Embedded Systems: Used in older embedded systems requiring non-volatile memory for storing boot code or configuration data.
• Industrial Control Equipment: Employed in legacy industrial control systems for storing program parameters and calibration data.
• Telecommunications Equipment: Utilized in older telecom infrastructure for storing system configuration and routing tables.
• BIOS Storage: Historically used to store BIOS (Basic Input/Output System) in older computer systems.

Features:

• 64-kb EEPROM: Offers 64 kilobits of non-volatile memory.
• Parallel Interface: Utilizes a parallel interface for fast data access.
• Fast Access Time: Features a 90ns access time, enabling quick read and write operations.
• Automatic Page Write: Supports automatic page write, simplifying write operations.
• Data Protection: Includes data protection features to prevent accidental writes.
• High Endurance: Provides high endurance for long-term data storage.

Benefits:

• Non-Volatile Storage: Retains data even without power, ensuring data persistence.
• Fast Data Access: The parallel interface and fast access time enable quick read and write operations.
• Simplified Write Operations: Automatic page write simplifies data programming.
• Data Security: Data protection features prevent unintentional data loss.
• Long-Term Reliability: High endurance ensures reliable data storage over an extended lifespan.

Additional Details:

The CAT28C64BT13-90T operates with a 5V power supply and is typically available in a DIP package. The device features a self-timed write cycle. Given its 'END-OF-LIFE' category, the CAT28C64BT13-90T is no longer in production and replacements may require significant redesign.
