71V65903S80PFGI

Overview

The Renesas 71V65903S80PFGI is a 9Mb (512K x 18) synchronous SRAM IC utilizing Zero Bus Turnaround (ZBT) technology. It features an 8 ns access time and operates on a single 3.3V supply within the 3.135V to 3.465V range. The device is housed in a 100-TQFP (14x14) surface-mount package and supports parallel data interfaces for high-speed memory applications.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates dead bus cycles during read-to-write or write-to-read transitions, maximizing throughput efficiency.
• Integrated address, data-in, and control signal registers enable synchronous operation with flow-through outputs that do not add latency to output data.

Applications

• High-performance embedded systems requiring fast random access memory
• Network infrastructure equipment demanding low-latency data buffering
• Industrial automation controllers needing reliable volatile storage

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements against specific manufacturing processes. Ensure voltage levels match system specifications before integration.

Selection Notes

Select this model when ZBT performance is required over standard synchronous SRAMs. The 100-TQFP package suits designs prioritizing board space efficiency. Verify thermal management capabilities for the -40°C to 85°C operating range if deployed in industrial environments.

Part Context

This component belongs to the IDT 71V65703/903 family of synchronous SRAMs. It shares architectural similarities with other members like the 71V65903S80BQ but differs in pinout and packaging. The family is designed for applications requiring high-speed data processing without bus turnaround delays.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Check manufacturer announcements for potential end-of-life replacements or pin-compatible alternatives within the same product line.
