71V3577YS85PFG

Overview

The IDT71V3577YS85PFG is a high-speed Synchronous ZBT SRAM organized as 128K x 36. It features an 8.5 ns access time and operates on a 2.5V core voltage with 3.3V I/O levels. The device utilizes a flow-through architecture without output registers, supporting burst modes for efficient data transfer. Packaged in a 100-pin TQFP, it is designed for applications requiring fast memory access and low power consumption.

Feature Summary

• Synchronous Zero Bus Turnaround (ZBT) technology enables high-speed data transfers with minimal wait states.
• Flow-through architecture provides immediate data availability at the outputs without pipeline latency.
• Integrated burst counter supports linear or interleaved burst sequences for single-cycle deselect operations.

Applications

• High-performance cache memory systems
• Network routing and switching equipment
• Telecommunications base stations

Procurement Notes

Verify the specific suffix 'YS' against the manufacturer's current datasheet to confirm pinout compatibility and electrical characteristics. Ensure the ordering part number matches the exact package type and temperature grade required for your design. Cross-reference with Renesas Electronics documentation as IDT products are now managed under their portfolio.

Selection Notes

Select this component when a synchronous interface is preferred over asynchronous for higher system bandwidth. The 36-bit width is suitable for error correction code (ECC) implementations. Consider the 2.5V core voltage for power efficiency while maintaining 3.3V I/O compatibility with standard logic families.

Part Context

This part belongs to the IDT 71V35xx series of synchronous SRAMs. It shares architectural similarities with other members like the 71V3577S but differs in speed grade and packaging options. The series is widely used in embedded systems requiring fast, reliable static random-access memory solutions.

Replacement Considerations

Check for direct substitutes within the 71V3577 family with different speed grades or package variations. Verify if newer revisions from Renesas offer equivalent functionality with updated compliance standards.
