71V547S80PFG

Overview

The 71V547S80PFG is a Synchronous Burst SRAM manufactured by Renesas Electronics Corporation. It features a memory organization of 128K x 36 bits, providing a total capacity of 4.5 Mbit. The device supports a maximum clock frequency of 100 MHz with an access time of 8 ns. It operates on a single 3.3V power supply, with voltage limits ranging from 3.135 V to 3.465 V. The component utilizes a parallel interface and is housed in a 100-pin TQFP package.

Feature Summary

• Supports synchronous burst read operations for high-speed data transfer
• Features flow-through architecture for continuous data processing
• Includes dedicated chip enable and output enable controls

Applications

• High-performance computing systems requiring fast cache memory
• Network infrastructure equipment needing low-latency buffering
• Industrial control systems utilizing synchronous logic interfaces

Procurement Notes

Verify the specific suffix against official documentation, as the provided model lacks the final character indicating package or temperature grade. Confirm current manufacturing status via Renesas datasheets, as similar variants may be obsolete. Ensure compatibility with existing board layouts for the 100-pin form factor before procurement.

Selection Notes

Select this component when a 128K x 36 organization is required for wide data paths. Compare access times and clock frequencies against system bus requirements. Verify that the 3.3V I/O levels match the host processor specifications. Consider the thermal characteristics of the TQFP package for the intended operating environment.

Part Context

This part belongs to the 71V547 series of Synchronous ZBT SRAMs. These devices are designed for applications demanding high bandwidth and low latency. The series typically offers various speed grades and organizational options to fit different system architectures while maintaining pin compatibility within the family.

Replacement Considerations

Check for direct substitutes such as the 71V547S100PFGI8. Verify if alternative speed grades meet the timing requirements. Ensure any replacement maintains the same 128K x 36 organization and 100-pin TQFP footprint.
