71V2546S100PFG8

Overview

The 71V2546S100PFG8 is a 4.5 Mbit Synchronous Burst Static Random Access Memory (SRAM) manufactured by Renesas Electronics Corporation. It features a memory organization of 128K words by 36 bits, utilizing a parallel interface with Single Data Rate (SDR) ZBT technology. The device supports a maximum clock frequency of 100 MHz and offers an access time of 5 ns. It operates within a supply voltage range of 3.135 V to 3.465 V and is housed in a 100-pin Thin Quad Flat Package (TQFP).

Feature Summary

• Supports high-speed synchronous burst read/write operations via ZBT architecture.
• Provides a wide 36-bit data bus for efficient data throughput.
• Features flow-through mode for continuous data streaming without wait states.

Applications

• High-performance networking equipment requiring fast packet buffering.
• Industrial control systems needing reliable real-time data storage.
• Telecommunications infrastructure utilizing synchronous memory interfaces.

Procurement Notes

Verify the specific suffix 'G8' against official Renesas documentation to confirm package and environmental compliance details. Confirm current production status as some variants in this series may be subject to end-of-life notices. Ensure compatibility with 3.3V logic levels and check moisture sensitivity handling requirements prior to assembly.

Selection Notes

Select this component when a 36-bit wide synchronous SRAM interface is required at 100 MHz speeds. Compare against the 71V2546S133PFG8 if higher clock frequencies are needed, or the 71V2546S150PFG8 for faster access times. Ensure the design accommodates the 100-TQFP footprint and 3.3V power domain constraints.

Part Context

This part belongs to the 71V2546 family of synchronous SRAMs, designed for applications demanding high bandwidth and low latency. The family typically includes variants with different access speeds and packaging options, all sharing the same core 128K x 36 bit architecture and ZBT technology for optimized system performance.

Replacement Considerations

Official substitutes include the 71V2546S133PFG8 and 71V2546S150PFG8, which offer faster clock speeds while maintaining pin compatibility. Verify that the target application can support the increased speed specifications of these alternative parts.
