71V3559S75PFGI

Overview

The IDT 71V3559S75PFGI is a Synchronous ZBT SRAM IC with a memory organization of 256K x 18, providing a total capacity of 4.5Mb. It features an access time of 7.5 ns and operates on a single 3.3V power supply within the range of 3.135V to 3.465V. The device utilizes a parallel interface and is housed in a 100-TQFP (14x14) package. It supports synchronous operation with burst counters and single-cycle deselect capabilities.

Feature Summary

• Supports synchronous operation with flow-through outputs
• Includes integrated burst counter for sequential data access
• Enables single-cycle deselect for flexible bus control

Applications

• High-speed cache memory systems
• Network routing equipment buffers
• Telecommunications signal processing

Procurement Notes

Verify component authenticity through authorized Renesas Electronics distributors. Confirm RoHS compliance status as manufacturing revisions may affect environmental certifications. Validate package integrity upon receipt to ensure pin alignment matches the 100-TQFP specification before integration into PCB assemblies.

Selection Notes

Select this component when a 4.5Mb synchronous SRAM with 7.5 ns latency is required. Ensure the design accommodates the 100-pin TQFP footprint and 3.3V logic levels. Consider thermal dissipation requirements for the surface-mount package in dense circuit layouts.

Part Context

This part belongs to the IDT 71V3559 family of Synchronous ZBT SRAMs. It shares architectural similarities with other variants in the series but differs in speed grade and package type. The 'S' suffix typically denotes specific speed binning, while 'PFGI' indicates the TQFP package and lead-free finish.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing system timing constraints if considering alternative vendors or speed grades within the same memory architecture.
