The Xicor X2004DI-20 is a 4K CMOS Nonvolatile Static RAM (NVSRAM) incorporating a static RAM array with a nonvolatile element in each memory cell. The memory array is overlaid bit-by-bit with a floating gate EEPROM array. This allows data to be transferred in parallel from RAM to EEPROM when power is lost, preserving data integrity. On power-up, data can be transferred from the EEPROM to the RAM.

Applications:

• Data logging
• Meter reading
• Automatic test equipment
• Robotics
• Point-of-sale terminals
• Medical equipment

Features:

• 4K (512 x 8) nonvolatile static RAM
• Unlimited read, write, and recall cycles
• Automatic STORE on power loss
• STORE triggered by hardware or software
• RECALL to RAM on power-up
• Data retention > 10 years
• Single 5V supply
• TTL compatible
• Industrial temperature range

Benefits:

• Increased system reliability: The nonvolatile memory ensures data is retained even during power outages, preventing data loss and ensuring system uptime.
• Simplified system design: The integrated RAM and EEPROM reduce component count and simplify board layout.
• Improved performance: Fast read and write access times enable high-speed data processing.
• Enhanced data security: Nonvolatile storage protects sensitive data from unauthorized access or modification.
• Extended product lifespan: The high endurance of the EEPROM cells ensures long-term data storage reliability.

Additional Details:

The X2004DI-20 operates from a single 5V power supply. It features TTL compatible inputs and outputs, allowing for easy integration with other digital logic circuits. The device also offers a hardware STORE function, which allows the user to manually trigger the transfer of data from RAM to EEPROM. Its industrial temperature range makes it suitable for use in harsh environments.
