7005S15PFI8

Overview

The Renesas Electronics Corporation 7005S15PFI8 is a dual-port static random-access memory (SRAM) device with a storage capacity of 64 kbit, organized as 8K x 8. It features an asynchronous parallel interface and a maximum access time of 15 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 64-pin TQFP package. It is designed for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two masters
• Asynchronous operation with fast 15 ns access time
• Integrated master/slave semaphore functionality for bus arbitration

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microcontroller applications
• Data logging and temporary storage in industrial control units

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations such as PFI versus PFI8 may indicate differences in packaging or moisture sensitivity levels. Confirm RoHS compliance status and lead-free specifications prior to procurement, as older variants often lack these certifications. Ensure compatibility with existing PCB footprints and reflow profiles specific to the TQFP-64 package type.

Selection Notes

Select this component when a system requires independent read/write ports for concurrent data handling without external arbitration logic. The 15 ns speed suits moderate-to-high frequency asynchronous interfaces. Verify that the 8K x 8 organization meets address space requirements and that the TQFP-64 package fits the thermal and spatial constraints of the target design.

Part Context

This part belongs to the Renesas 7005 series of dual-port SRAMs, which are designed for applications requiring high-speed data sharing between processors. The series typically includes variants with different access times and package options, allowing designers to balance performance, cost, and physical size requirements for complex embedded architectures.

Replacement Considerations

Direct replacements include other 7005 series variants like the 7005L25PFI or 7005S25PFI, though access times and temperature ranges differ. Cross-vendor equivalents must be verified for pin compatibility and electrical characteristics. Always consult manufacturer substitution guides for confirmed drop-in alternatives.
