The Xicor X20C16D-55 is a 16K CMOS Nonvolatile Static RAM (NVSRAM) device. It combines the features of static RAM (SRAM) with non-volatile EEPROM backup, ensuring data retention even when power is lost.

Applications

• Data Logging: For storing critical data in industrial applications, ensuring data retention during power outages.
• Meter Reading: Used in smart meters to store energy consumption data without power supply.
• Medical Equipment: For storing patient data or calibration settings in medical devices.
• Industrial Control Systems: For storing parameters and configurations in PLCs and other control systems.
• Point-of-Sale (POS) Systems: Used in POS terminals to store transaction logs and other important data.

Features

• Nonvolatile Storage: Retains data even when power is removed.
• Fast Access Time: 55ns access time for quick data retrieval.
• Automatic Store on Power-Down: Automatically stores data to EEPROM when power is lost.
• Software Store: Allows manual storage of data to EEPROM via software command.
• Automatic Recall on Power-Up: Automatically recalls data from EEPROM when power is restored.
• CMOS Technology: Low power consumption due to CMOS technology.
• JEDEC Standard Pinout: Standard pinout for easy integration.

Benefits

• Data Retention: Ensures data integrity even during power failures.
• Fast Read/Write: Provides fast access to data for efficient system operation.
• Automatic Backup: Simplifies data management with automatic store and recall functions.
• Low Power Consumption: Extends battery life in portable applications.
• Easy Integration: Standard pinout simplifies integration into existing systems.
