The CY14E256L-SZ25XIT is a 256Kb (32K x 8) nonvolatile Static RAM (nvSRAM) manufactured by Cypress Semiconductor (now Infineon Technologies). nvSRAMs combine the fast access speeds of SRAM with the non-volatile data storage of EEPROM, making them ideal for applications where data retention is critical, even when power is lost. The SZ25XIT designation refers to specific packaging and temperature range options.

Applications

• Data Logging: Securely storing data in applications where power loss is possible, such as industrial data loggers.
• Meter Reading: Retaining critical meter readings in smart meters during power outages.
• Industrial Control: Maintaining control parameters and configuration data in industrial automation systems.
• Medical Devices: Storing patient data and device settings in portable medical equipment.
• Gaming Machines: Preserving game state and scores in electronic gaming devices.

Features

• Memory Size: 256Kb (32K x 8 bits)
• Non-Volatile: Data is automatically retained on power loss, without external battery backup.
• Fast Access Time: SRAM-like read and write speeds, typically around 25 ns.
• Automatic Store: Data is automatically backed up to non-volatile memory on power-down.
• Automatic Recall: Data is automatically restored from non-volatile memory on power-up.
• Unlimited Endurance: Virtually unlimited read and write cycles to the SRAM portion of the memory.
• Operating Voltage: Wide operating voltage range, typically from 2.7V to 5.5V.
• Temperature Range: Industrial temperature range (SZ designation implies extended temperature range).
• Package: SOIC (Small Outline Integrated Circuit) package (SZ designation implies specific package details).

Benefits

• Data Security: Ensures data integrity and retention even in the event of power failure.
• High Performance: Provides fast read and write access speeds comparable to SRAM.
• Simplified System Design: Eliminates the need for external battery backup circuits.
• Increased Reliability: Offers superior reliability compared to traditional battery-backed SRAM solutions.
• Reduced Power Consumption: Low power consumption compared to other non-volatile memory technologies.
