71V3559S80PFGI8

Overview

The IDT71V3559S80PFGI8 is a synchronous single data rate zero bus turnaround SRAM IC manufactured by Renesas Electronics. It features a storage capacity of 4.5Mb organized as 256K x 18 bits with a parallel interface. The device supports a maximum clock frequency of 100 MHz and offers an access time of 8 ns. It operates within a supply voltage range of 3.135V to 3.465V and is housed in a 100-TQFP (14x14) surface-mount package.

Feature Summary

• Supports high-speed synchronous operation with a 100 MHz clock frequency for efficient data throughput.
• Utilizes zero bus turnaround technology to minimize latency during read-to-write transitions.
• Provides a wide 18-bit data width suitable for complex data processing applications.

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment demanding low-latency buffering
• Industrial automation controllers needing reliable volatile storage

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status as specifications may vary by production batch. Check moisture sensitivity level handling requirements prior to assembly. Ensure the specific suffix matches design requirements for pinout and electrical characteristics.

Selection Notes

Select this model when a 100 MHz synchronous SRAM with 18-bit width is required. Compare against the 71V3559S85 variant if slower speeds suffice. Consider the 71V3558 series for faster access times if performance needs exceed 8 ns. Evaluate package constraints to ensure compatibility with the 100-TQFP footprint.

Part Context

This component belongs to the IDT 71V3559 family of synchronous SRAMs, designed for high-bandwidth applications. It complements other devices like the 71V3559S85PFGI8, which shares similar architecture but operates at lower frequencies. The family emphasizes reliability and speed for embedded memory solutions.

Replacement Considerations

The 71V3559S85PFGI8 serves as a compatible alternative with identical organization but reduced speed. Verify pin compatibility and electrical parameters before substitution. No direct public substitute part numbers are confirmed for exact replacement.
