The Xicor X2212P is a 4096-bit nonvolatile static RAM (NVSRAM), organized as 512 words by 8 bits. This memory integrates fast SRAM with non-volatile EEPROM technology. In the event of a power loss, data automatically transfers from the SRAM to the EEPROM, ensuring data retention without the need for batteries or external backup systems.

Applications

• Industrial Automation: Retains critical machine settings and process parameters during power interruptions.
• Medical Equipment: Preserves patient data and equipment configurations in case of power failure.
• Point-of-Sale (POS) Systems: Ensures transaction data integrity in retail environments.
• Networking Equipment: Stores configuration data for routers, switches, and other network devices.
• Aerospace and Defense: Used in applications where reliable data storage is crucial and battery backup is not feasible.

Features

• 4096-bit Memory: Organized as 512 words x 8 bits for substantial data storage.
• Nonvolatile Data Storage: Automatic data transfer to EEPROM upon power loss guarantees data retention.
• Unlimited Read/Write Cycles: SRAM provides fast and unlimited read/write operations during normal operation.
• Automatic Store Operation: Simplifies system design by automating the data backup process.
• Fast Access Time: Enables quick data retrieval from the SRAM.

Benefits

• Data Protection: Prevents data loss due to power outages, ensuring system reliability.
• Simplified Design: Eliminates the complexity and cost associated with battery backup solutions.
• Increased Reliability: Combines the benefits of fast SRAM with robust nonvolatile EEPROM.
• Fast Performance: SRAM access speeds allow for rapid data manipulation.
• Reduced Maintenance: No battery replacements are required, lowering maintenance costs.

Additional Details

The X2212P typically operates at 5V. During a power loss, the device initiates a store cycle, transferring the SRAM contents to the EEPROM. This process takes a few milliseconds. Proper decoupling capacitors should be used on the power supply pins to minimize noise and ensure stable operation. The datasheet contains detailed timing diagrams, power consumption data, and operating temperature ranges. The 'P' suffix generally indicates a specific package type, such as a DIP (Dual In-line Package), facilitating easy integration into circuit boards.
