• Provides fast access times for efficient system performance in real-time applications.
• Operates on a standard 3.3V power supply with defined voltage tolerances.

Applications

• High-performance embedded systems requiring fast data buffering
• Industrial equipment control units
• Network communication hardware

Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence status. Confirm package integrity and moisture sensitivity handling procedures prior to assembly. Cross-reference datasheet revisions to ensure compatibility with current design specifications and regulatory requirements.

Selection Notes

Select this model for designs requiring 256K x 18 organization with synchronous timing. Ensure the PCB layout accommodates the 100-pin TQFP footprint. Verify that the system clock frequency aligns with the 8 ns access time specification for optimal signal integrity.

Part Context

This component belongs to the 71V3559 series of synchronous SRAMs, designed for high-density memory applications. It shares architectural similarities with other members of the family but differs in pin count and package type, specifically utilizing the TQFP form factor for compact integration.

Replacement Considerations

Check for direct pin-compatible substitutes within the same series. Verify if alternative packages like BGA variants offer functional equivalence while meeting thermal and spatial constraints.
