71V3559S75PFG

Overview

The IDT71V3559S75PFG is a synchronous ZBT SRAM organized as 256K x 18 with a total capacity of 4.5 Mbit. It operates at a maximum clock frequency of 100 MHz with a 7.5 ns access time. The device supports 3.3V I/O levels and utilizes a pipelined output architecture with an internal burst counter. It is housed in a 100-pin TQFP package and functions within a standard commercial temperature range.

Feature Summary

• Supports high-speed synchronous operation with a 100 MHz clock rate
• Features a pipelined output architecture for improved throughput
• Includes an internal burst address counter for sequential data access

Applications

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

Procurement Notes

Verify the specific suffix PFG to confirm the 100-pin TQFP package configuration, as other suffixes may indicate different packaging or temperature grades. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as environmental declarations can vary by production batch and region. Ensure the supply chain source is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a 256K x 18 organization with synchronous interface is required. The 7.5 ns speed grade suits applications needing 100 MHz performance. Consider the TQFP-100 package if through-hole or specific board space constraints apply. Verify that the 3.3V I/O voltage level matches the system logic requirements before integration.

Part Context

This part belongs to the IDT 71V355x family of Synchronous ZBT SRAMs. These devices are designed for high-bandwidth applications requiring fast random access and burst capabilities. The family typically includes variants with different speeds, organizations, and packages to support diverse embedded memory needs in industrial and commercial electronics.

Replacement Considerations

Check for direct pin-compatible replacements within the same 71V355x series, such as the 71V3559S75BG in BGA format, noting the package change. Verify electrical compatibility with any alternative synchronous SRAMs offering similar 256K x 18 density and 100 MHz performance.
