71V547S80PFG8

Overview

The 71V547S80PFG8 is a Synchronous Single Data Rate (SDR) Static Random Access Memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a memory organization of 128K x 36 bits, resulting in a total storage capacity of 4.5 Mbit. The device supports parallel interface communication with an access time of 8 ns and a maximum clock frequency of 100 MHz. It operates within a supply voltage range of 3.135 V to 3.465 V and is housed in a 100-TQFP surface-mount package.

Feature Summary

• Supports synchronous single data rate (SDR) operation for high-speed data transfer via a parallel interface.
• Provides a wide data bus width of 36 bits per word to accommodate complex data processing requirements.
• Operates on a standard 3.3 V power supply rail suitable for general-purpose logic systems.

Applications

• High-performance computing systems requiring fast buffer memory
• Network infrastructure equipment utilizing packet buffering
• Industrial control systems needing rapid data acquisition

Procurement Notes

Verify component authenticity through authorized channels due to the part's end-of-life status. Confirm that the specific package variant matches the design footprint, as sourcing may involve obsolete inventory or alternative distributors. Ensure compliance with RoHS3 standards if required by the target assembly process.

Selection Notes

Select this component when a 36-bit data path is necessary for system architecture compatibility. Consider the 8 ns access speed against available alternatives if higher throughput is required. Evaluate the 100-pin TQFP package constraints regarding board space and thermal management capabilities during the layout phase.

Part Context

This SRAM belongs to the 71V547 series, designed for applications demanding moderate density with wide data buses. It serves as a bridge between high-speed processors and slower storage media, facilitating efficient data handling in embedded environments where deterministic timing is critical for system stability.

Replacement Considerations

The 71V547S100PFGI8 is a confirmed substitute offering similar specifications with a 10 ns access time. Verify pinout compatibility and electrical characteristics before implementation to ensure seamless integration into existing designs without hardware modifications.
