71V547S100PFG

Overview

The IDT71V547S100PFG is a 3.3V synchronous ZBT SRAM with a memory organization of 128K x 36, providing a total capacity of 4 Mbit. It features a maximum clock frequency of 66 MHz and an access time of 10 ns. The device operates within a supply voltage range of 3.135 V to 3.465 V and supports parallel interface communication. It is housed in a 100-pin TQFP package suitable for surface mount installation.

Feature Summary

• Supports Zero Bus Turnaround (ZBT) technology to eliminate dead cycles between read and write operations
• Features flow-through outputs for continuous data availability without pipeline latency
• Includes a burst counter for sequential access efficiency

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network routers and switches
• Data storage in industrial control systems requiring fast access times

Procurement Notes

Verify the specific suffix 'PFG' against manufacturer documentation to confirm pinout and package dimensions. Ensure compatibility with 3.3V logic levels and check for moisture sensitivity handling requirements during assembly. Confirm RoHS compliance status with current supplier declarations.

Selection Notes

Select this component when zero bus turnaround performance is required alongside flow-through output simplicity. Compare against pipelined alternatives if lower latency per cycle is prioritized over throughput continuity. Verify that the 128K x 36 organization matches system data width requirements.

Part Context

This part belongs to the IDT 71V547 series of synchronous ZBT SRAMs. It shares architectural similarities with other members like the 71V547S80 but differs in speed grade. The series is designed for applications needing high bandwidth without the complexity of pipelined architectures.

Replacement Considerations

IDT71V547S100PFGI8 is a documented equivalent variant.
