71V632S5PFGI

Overview

The 71V632S5PFGI is a synchronous single data rate (SDR) static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 2 Mbit organized as 64K words by 32 bits. The device operates with a maximum clock frequency of 100 MHz and supports a pipeline burst architecture for high-speed parallel data transfer. Key electrical specifications include a 5 ns access time and a supply voltage range of 3.135 V to 3.465 V. It is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm, suitable for surface-mount assembly.

Feature Summary

• Supports synchronous single data rate operation with a pipeline burst architecture for efficient high-speed data handling.
• Provides a wide 32-bit data bus interface to minimize the number of external components required for system design.
• Operates within a standard 3.3 V power supply range while maintaining reliable performance across industrial temperature conditions.

Applications

• High-performance networking equipment requiring fast packet buffering
• Telecommunications infrastructure systems
• Industrial control systems with real-time data processing needs

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS3 compliance status and check for specific package labeling changes documented in recent Product Change Notices. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when a 32-bit wide synchronous SRAM interface is required for bandwidth-intensive applications. The 100 MHz clock speed and 5 ns access time make it suitable for systems needing rapid data retrieval. Consider the 100-TQFP package constraints for PCB space and ensure the design supports the necessary 3.3 V power delivery network stability.

Part Context

This part belongs to the Renesas 71V6xx series of synchronous SRAMs, designed for high-throughput memory applications. It succeeds earlier asynchronous designs by offering synchronized data transfers aligned with system clocks. The 71V632S5PFGI specifically addresses the need for wider data paths in embedded systems compared to narrower 8-bit or 16-bit alternatives.

Replacement Considerations

No officially confirmed substitute part numbers are available in public documentation for this specific discontinued model. Designers should evaluate newer generation synchronous SRAMs from Renesas or other manufacturers, ensuring pin compatibility and electrical parameter alignment during migration.
