71V547XS100PFG

Overview

The IDT 71V547XS100PFG is a high-speed synchronous static random-access memory (SRAM) device belonging to the ZBT family. It features a memory organization of 128K words by 36 bits, providing a total storage capacity of 4 megabits. The component supports a maximum clock frequency of 100 MHz with an access time of 10 nanoseconds. It operates on a single 3.3V power supply and utilizes a parallel interface. The device is housed in a 100-pin Thin Quad Flat Pack (TQFP) package designed for surface-mount technology.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates dead cycles between read and write operations
• Single Read/Write control pin simplifies system logic design
• Internally synchronized output buffer enable removes external control requirements
• Supports four-word burst capabilities with interleaved or linear modes

Applications

• High-performance embedded systems requiring fast data buffering
• Network infrastructure equipment demanding low-latency memory access
• Industrial automation controllers utilizing synchronous data processing
• Telecommunications hardware implementing flow-through output architectures

Procurement Notes

Verify the exact suffix designation against manufacturer documentation, as generic model strings often omit critical voltage or temperature variants. Confirm RoHS compliance status and moisture sensitivity levels prior to integration. Ensure the specific package type matches the target PCB footprint specifications. Cross-reference part numbers with current Renesas Electronics catalogs due to historical corporate acquisitions affecting availability.

Selection Notes

Select this component when system timing requires synchronous operation with zero wait states during bus turnaround. The 36-bit width suits applications needing wide data paths without parallel chip expansion. Evaluate thermal performance within the TQFP-100 enclosure for the intended operating environment. Consider the internal synchronization features to reduce board-level control complexity compared to asynchronous alternatives.

Part Context

This device is part of the broader 71V547 series of synchronous SRAMs originally developed by Integrated Device Technology. Following the acquisition of IDT by Renesas Electronics, production and support responsibilities transitioned accordingly. The series is characterized by its ZBT technology, which optimizes throughput for high-speed digital signal processing and communication protocols requiring rapid memory cycling.

Replacement Considerations

The 71V547S100PFGI8 from Renesas Electronics serves as a direct functional equivalent. Verify pin compatibility and electrical parameters before substitution.
