71V3559S75PFGI8

Overview

The Renesas Electronics Corporation 71V3559S75PFGI8 is a Synchronous Single Data Rate (SDR) Zero Bus Turnaround (ZBT) Static Random Access Memory (SRAM) integrated circuit. It provides a total storage capacity of 4.5 Megabits, organized as 256K words by 18 bits. The device features a parallel memory interface with an access time of 7.5 nanoseconds. It operates within a supply voltage range of 3.135V to 3.465V and supports surface mount installation in a 100-TQFP package measuring 14x14 mm. The component is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Supports synchronous single data rate operation with zero bus turnaround technology for high-speed data transfer efficiency.

Applications

• High-performance embedded systems requiring fast random access memory.
• Network infrastructure equipment utilizing parallel SRAM interfaces.
• Industrial control systems operating within standard commercial temperature ranges.

Procurement Notes

Verify current availability status as the product may be subject to discontinuation notices. Confirm RoHS compliance requirements against specific project standards, as this component may not meet all environmental directives. Ensure the 100-TQFP package dimensions align with existing PCB footprints. Validate that the 3.3V I/O logic levels are compatible with the target system's voltage domains before finalizing procurement orders.

Selection Notes

Select this component when a 4.5Mb capacity with 7.5ns access speed is required in a 100-pin TQFP form factor. It is suitable for designs needing ZBT synchronization without complex pin counts associated with larger packages. Consider the 18-bit word width for applications requiring built-in error correction or parity bits. Evaluate thermal performance within the 0°C to 70°C range for the intended enclosure environment.

Part Context

This part belongs to the 71V3559 family of synchronous ZBT SRAMs from Renesas. The 'S' suffix typically denotes specific timing characteristics, while '75' indicates the 7.5ns access speed. The 'PFGI8' suffix identifies the 100-TQFP package type and industrial/commercial temperature rating. This family offers a balance of density and speed for mid-range memory applications.

Replacement Considerations

Check for direct cross-reference parts within the same 71V3559 series with different speed grades or package options. Verify if newer revisions of the component have updated labeling or substrate changes documented in Product Change Notices. Ensure any substitute maintains the 18-bit data width and synchronous interface compatibility.
