STK14CA8-NF25ITR

Memory IC Overview

The STK14CA8-NF25ITR is a 1 Mbit (128K x 8) nonvolatile static RAM featuring QuantumTrap storage. It provides 25 ns access time and operates on a single 3.0V supply (+20%, -10%). The device supports unlimited read/write endurance with up to 200,000 STORE cycles and 20-year data retention. It utilizes a 32-pin SOIC package for industrial temperature ranges (-40°C to +85°C).

Memory IC Feature Summary

• Integrates fast SRAM with nonvolatile QuantumTrap elements for seamless data preservation.
• Executes automatic STORE operations upon power loss detection without external control.
• Supports hardware and software controlled STORE and RECALL sequences.
• Provides unlimited recall cycles from nonvolatile storage to SRAM.

Memory IC Applications

• Industrial control systems requiring persistent configuration data.
• Telecommunications equipment needing reliable parameter storage.
• Automotive electronics demanding high reliability under varying temperatures.
• Medical devices preserving critical operational settings during power interruptions.

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms industrial temperature range compliance (-40°C to +85°C) rather than commercial grade. Confirm the 'NF' designation matches the required 32-pin SOIC package and matte tin lead finish. Ensure the 'TR' suffix aligns with tape and reel handling requirements for automated assembly processes.

Memory IC Selection Notes

Select this component when unlimited write endurance is critical compared to flash-based alternatives. Consider the 25 ns speed for high-frequency bus interfaces. Evaluate the VCAP capacitor requirement for AutoStore functionality. Verify that the 3.0V operating voltage aligns with the system power rail specifications.

Memory IC Part Context

This part belongs to the STK14CA8 family of nvSRAMs, which combines SRAM speed with nonvolatile retention. The series offers various access times and packages. The NF25 variant specifically targets applications needing 25 ns performance in a surface-mount SOIC footprint.

Memory IC Replacement Considerations

Direct pin-compatible replacements within the same family include STK14CA8-NF35ITR and STK14CA8-NF45ITR, differing only in access speed. Cross-family replacements require verification of interface compatibility and voltage levels.
