71V547XS100PF

Overview

The IDT71V547XS100PF is a high-speed synchronous static random-access memory (SRAM) component manufactured by Integrated Device Technology. It features a memory organization of 128K x 36 bits, providing a total storage capacity of 4.5 Mbit. The device operates with a maximum clock frequency of 100 MHz and supports a typical access time of 10 ns. It utilizes a 3.3V power supply for the core and includes Zero Bus Turnaround (ZBT) technology to eliminate dead cycles between read and write operations. The component is housed in a standard 100-pin plastic thin quad flatpack (TQFP) package.

Feature Summary

• Supports high-performance system speeds through synchronous operation at up to 100 MHz.
• Integrates ZBT technology to ensure no dead cycles occur between write and read bus transitions.
• Features internally synchronized output buffer enable to simplify control logic requirements.
• Includes a burst counter for efficient sequential data access.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network routers and switches
• Signal processing systems requiring low-latency data access

Procurement Notes

Verify the specific suffix 'X' against official Renesas or IDT documentation to confirm exact speed grade and pinout compatibility. Ensure the procurement source provides valid RoHS compliance certificates as required for modern electronic assemblies. Confirm that the 100-pin TQFP package dimensions match the target PCB footprint specifications before finalizing orders.

Selection Notes

Select this component when a 128K x 36 bit configuration is required for synchronous applications. It is suitable for designs needing 100 MHz performance with ZBT efficiency. Consider alternative packages like BGA if board space constraints exist, as other variants in the series may offer different form factors while maintaining identical electrical characteristics.

Part Context

This part belongs to the 71V547 family of synchronous ZBT SRAMs. The family is characterized by its ability to handle high-bandwidth data streams without bus turnaround delays. The manufacturer has transitioned from IDT to Renesas Electronics, meaning technical support and datasheets are now hosted under the Renesas brand name while retaining the original IDT part numbering conventions.

Replacement Considerations

The IDT71V547S100PFI is a confirmed equivalent part number within the same product family. Verify that the replacement maintains the same 100-pin TQFP package and 10 ns access time specifications to ensure direct compatibility with existing circuit designs.
