JS28F320J3D75D TR

Memory IC Overview

The JS28F320J3D75D TR is a 32Mb parallel NOR flash memory IC from Micron's StrataFlash J3 series. It features a 56-TSOP package and supports 4M x 8 or 2M x 16 organization. The device operates with a 75 ns access time and a write cycle time of 75 ns. Supply voltage ranges from 2.7V to 3.6V, and it functions within an industrial temperature range of -40°C to 85°C.

Memory IC Feature Summary

• Supports asynchronous parallel interface for direct host connection
• Non-volatile storage architecture retains data without power
• Industrial-grade thermal stability for demanding environments

Memory IC Applications

• Embedded firmware storage in industrial controllers
• Code execution in XIP (Execute-In-Place) systems
• Data logging in automotive telematics units

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS3 compliance and MSL level 3 handling requirements during assembly. Cross-reference part numbers carefully as suffixes may indicate packaging variations rather than functional changes. Validate lead times with suppliers given the end-of-life nature of this specific item.

Memory IC Selection Notes

Select this component when legacy parallel NOR compatibility is required for existing board designs. Ensure voltage levels match the 2.7V to 3.6V operating range. Consider the 56-pin TSOP footprint constraints during PCB layout. Verify that the 32Mb density meets system storage needs without requiring external memory expansion.

Memory IC Part Context

This part belongs to Micron's StrataFlash J3 family, designed for high-reliability embedded applications. It represents a transition point in Micron's NOR portfolio, offering robust performance in a compact surface-mount package. The J3 series is known for consistent timing characteristics across varying voltage conditions.

Memory IC Replacement Considerations

Check for JS28F128J3F75A for lower density options within the same interface family. Verify pinout compatibility before substituting with other 56-TSOP NOR devices. Consult Micron's official cross-reference tools for validated alternatives.
