The CY14B256Q2A-SXI is a 256-Kbit (32K x 8) nonvolatile static RAM (nvSRAM) manufactured by Cypress Semiconductor. nvSRAMs combine the fast access times of SRAM with the non-volatility of flash memory, retaining data even when power is removed. This makes them ideal for applications requiring frequent writes and long-term data storage.

Applications

• Data Logging: Used in industrial data loggers, medical equipment, and environmental monitoring systems to store data persistently.
• Metering: Employed in smart meters for electricity, water, and gas to record usage data accurately and reliably.
• Gaming Devices: Utilized in arcade machines and gaming consoles to store game settings and high scores.
• Industrial Control: Found in programmable logic controllers (PLCs) and human-machine interfaces (HMIs) to store configuration data and real-time parameters.
• Medical Devices: Used in implantable medical devices and patient monitoring equipment for storing critical patient data.

Features

• 256-Kbit Density: 32K x 8 organization provides ample storage for configuration data and variables.
• Fast Access Time: Offers a fast read and write access time of 45 ns.
• Nonvolatile Data Storage: Retains data indefinitely, even when power is removed.
• Automatic Store on Power-Down: Automatically stores data to nonvolatile memory upon power loss.
• Automatic Recall on Power-Up: Automatically recalls data from nonvolatile memory upon power restoration.
• Unlimited Read/Write Cycles: Supports an unlimited number of read and write cycles.

Benefits

• Data Retention: Ensures data is preserved even during power outages.
• High Performance: Fast access times enable real-time data processing.
• Reliability: Provides dependable operation with unlimited read/write cycles.
• Ease of Use: Automatic store and recall functions simplify system design.
• Versatile Application: Suitable for a wide range of applications requiring nonvolatile memory.

Additional Details

The CY14B256Q2A-SXI operates from a 3.3V power supply. It is available in a SOIC (Small Outline Integrated Circuit) package. The device includes a capacitor to store the data during power loss. It uses a SONOS (Silicon-Oxide-Nitride-Oxide-Silicon) nonvolatile memory technology. The operating temperature range is -40°C to +85°C. It is suitable for use in harsh industrial environments. This nvSRAM offers a combination of speed and non-volatility, making it ideal for critical data storage applications. The fast access times allow for in-place writes and reads without the need for external EEPROM or flash memory.
