71V547S80PFGI

Overview

The 71V547S80PFGI is a synchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It features a storage organization of 128K x 36 bits, providing a total capacity of 4.5 Mbit. The device operates with an access time of 8 ns and supports a maximum clock frequency of 80 MHz. It utilizes a parallel interface and functions within a supply voltage range of 3.135 V to 3.465 V. The component is housed in a 100-TQFP surface-mount package.

Feature Summary

• Supports Zero-Bus Turnaround (ZBT) technology for high-speed data transfer
• Features flow-through output mode for continuous data access
• Includes an internal burst counter for sequential read operations

Applications

• High-performance embedded systems requiring fast data buffering
• Industrial equipment control units
• Network infrastructure hardware

Procurement Notes

Verify the exact suffix configuration when ordering, as variations such as PFGI8 or PFI may indicate differences in packaging or temperature ratings. Confirm current availability status, as this specific part number may be subject to end-of-life notices or discontinuation. Ensure compatibility with existing board layouts regarding the 100-pin TQFP footprint and electrical specifications before procurement.

Selection Notes

Select this component for designs requiring 36-bit wide data paths and synchronous operation at 80 MHz. Compare against the 71V547S100PFGI8 if higher speed is needed, or consider the 71V3557 series for alternative pinouts. Verify that the system power supply strictly adheres to the 3.3V nominal requirement to ensure reliable operation within the specified temperature range.

Part Context

This SRAM belongs to the 71V547 family of synchronous memories from Renesas, formerly IDT. The family is characterized by ZBT technology, which optimizes throughput without sacrificing latency. These devices are designed to replace asynchronous SRAMs in high-speed applications while offering lower power consumption and easier integration with modern processors.

Replacement Considerations

The 71V547S100PFGI8 is listed as a verified substitute for the 71V547S80PFGI8.
