The Xicor X2210P10 is a 1024-bit nonvolatile static RAM (NVSRAM), organized as 128 words by 8 bits. This memory combines the speed of static RAM (SRAM) with the non-volatility of EEPROM. Upon power loss, the data stored in the SRAM is automatically transferred to the EEPROM, ensuring data retention without the need for batteries or external power sources.

Applications

• Industrial control systems: For storing critical parameters and setpoints that must be retained during power interruptions.
• Data logging: Ideal for applications where continuous data recording is essential, such as environmental monitoring or process control.
• Point-of-sale (POS) terminals: Ensures transaction data is preserved even in the event of a power outage.
• Metering equipment: Used in smart meters and other metering devices to store usage data reliably.
• Medical devices: In critical medical equipment, the NVSRAM can retain patient data and configuration settings.

Features

• 1024-bit capacity: Provides 128 bytes of nonvolatile storage.
• Nonvolatile storage: Automatically stores SRAM contents to EEPROM on power loss.
• Unlimited SRAM read/write cycles: Offers the performance of SRAM with the persistence of EEPROM.
• Automatic store on power loss: Simplifies system design by automatically backing up data.
• Fast SRAM access times: Enables rapid data access during normal operation.

Benefits

• Data integrity: Guarantees that critical data is preserved in the event of power failure.
• Simplified system design: Eliminates the need for battery backup circuits.
• High reliability: Combines proven SRAM and EEPROM technologies for robust performance.
• Fast operation: SRAM provides quick read and write times during normal operation.
• Reduced maintenance: No batteries to replace, reducing maintenance costs.

Additional Details

The X2210P10 typically operates from a 5V power supply. The store operation is triggered when the supply voltage drops below a predetermined threshold. The device is packaged in a DIP (Dual In-line Package), facilitating easy integration into through-hole circuit boards. For reliable operation, it's essential to follow the manufacturer's recommendations regarding power supply decoupling and operating temperature. The datasheet provides detailed information on timing specifications, power consumption, and environmental ratings. The 'P10' likely refers to a specific speed grade or temperature range variant of the X2210.
