The STK11C88-N25I is a 64Kb nonvolatile static RAM (nvSRAM) manufactured by Cypress Semiconductor Corp. It combines SRAM technology with nonvolatile data storage using SONOS (Silicon-Oxide-Nitride-Oxide-Silicon) flash memory cells. This device provides the fast access times of SRAM with the data retention of nonvolatile memory.

Applications

• Data logging
• Meter reading
• Industrial control systems
• Networking equipment
• Medical devices

Features

• 64Kb (8K x 8) memory organization
• Fast SRAM access times (25 ns)
• Automatic store on power-down
• Software-controlled store and recall
• Unlimited read, write, and recall cycles
• 1 million store cycles
• 10-year data retention
• Single 5V power supply
• RoHS compliant

Benefits

• Nonvolatile Data Storage: Retains data even when power is removed.
• Fast Access: Provides fast SRAM access times for quick read and write operations.
• Automatic Data Protection: Automatically stores data on power loss.
• High Endurance: Supports 1 million store cycles.
• Long Data Retention: Data is retained for at least 10 years.

Additional Details

The STK11C88-N25I combines a standard SRAM array with a nonvolatile storage element for each memory cell. When power is lost, the data in the SRAM is automatically copied to the nonvolatile memory. The device also supports software-controlled store and recall operations, allowing the user to manually store or retrieve data. This nvSRAM is ideal for applications that require both fast memory access and nonvolatile data storage. Detailed timing characteristics, power consumption, and package information can be found in the Cypress datasheet. The -N25I suffix indicates a specific speed grade and temperature range.
