71V546S100PFGI

Overview

The 71V546S100PFGI is a 4.5 Mbit Synchronous Single Data Rate (SDR) Zero Bus Turnaround (ZBT) Static Random Access Memory (SRAM) manufactured by Renesas Electronics Corporation. It features a memory organization of 128K x 36 bits and supports parallel interface operations at a maximum clock frequency of 100 MHz with a 5 ns access time. The device 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 high-speed synchronous data transfer via ZBT architecture to eliminate dead bus cycles during read-write transitions.
• Provides 36-bit wide data path for efficient handling of complex data structures in embedded systems.
• Operates on a single 3.3V power supply with TTL-compatible inputs.

Applications

• High-performance networking equipment requiring low-latency buffering.
• Industrial control systems utilizing real-time data processing.
• Telecommunications infrastructure involving signal processing tasks.

Procurement Notes

Verify component authenticity through authorized channels as the part status is obsolete. Confirm moisture sensitivity level (MSL 3) requirements for storage and reflow soldering processes. Ensure compatibility with existing PCB footprints and verify that replacement alternatives meet all electrical specifications before integration into production lines.

Selection Notes

Select this component for applications demanding fast, deterministic memory access without bus turnaround delays. Consider the 100-TQFP package constraints for thermal management and board space. Evaluate end-of-life status implications for long-term product support and identify suitable cross-reference parts from the manufacturer's portfolio if future availability is critical.
