The CY14B101LA-2S45XI is a 1-Mbit (128K x 8) Nonvolatile Static RAM (nvSRAM) manufactured by Cypress Semiconductor. It combines the fast access times of SRAM with the nonvolatile data storage of EEPROM, providing reliable data retention even when power is lost. This device is designed for applications that require frequent data writes and long-term data storage without the need for battery backup.

Applications

• Data Logging
• Metering Systems
• Industrial Control Systems
• Medical Equipment
• Networking Devices

Features

• 1-Mbit Nonvolatile SRAM: Provides fast read/write operations and nonvolatile data storage.
• Fast Access Time: 45 ns access time for rapid data retrieval.
• Automatic STORE on Power-Down: Automatically saves data to nonvolatile memory on power loss.
• Manual STORE/RECALL: Allows for user-controlled data storage and retrieval.
• Unlimited Read, Write, and RECALL Cycles: Ensures long-term data reliability.
• RoHS Compliant: Meets environmental standards for hazardous substance restrictions.

Benefits
