7027S12PFI8

Memory IC Overview

The 7027S12PFI8 is a high-speed synchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features a storage capacity of 512Kb, organized as 32K words by 16 bits. The device supports parallel interface operations with a maximum access time of 12 ns. It operates on a single 5V power supply within the range of 4.5V to 5.5V and is designed for industrial temperature applications ranging from -40°C to +85°C. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm, suitable for surface-mount technology.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous independent access to shared memory locations by two distinct processors or systems.
• Synchronous operation ensures precise timing alignment across both ports using a common clock signal for data integrity.
• Flow-through and pipelined output modes provide flexibility for optimizing data throughput in burst transfer applications.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring low-latency bidirectional data flow.
• Network switch and router memory architectures utilizing dual-processor control planes.
• Industrial automation controllers needing reliable concurrent read/write access for real-time process monitoring.

Memory IC Procurement Notes

Verify the specific suffix 'PFI8' against official Renesas documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing PCB footprints for the 100-TQFP form factor. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the part number with current Renesas lifecycle notices to verify availability and obsolescence status before finalizing procurement plans.

Memory IC Selection Notes

Select this component when system design requires true simultaneous dual-port access without arbitration overhead. The 12 ns speed grade suits applications demanding high bandwidth for burst data transfers. Consider the 5V logic compatibility if interfacing with legacy systems. Evaluate the 100-pin TQFP package constraints regarding board space and thermal dissipation capabilities relative to other available packages in the series.

Memory IC Part Context

This part belongs to the Renesas 7027S family of synchronous dual-port SRAMs. These devices are engineered for performance-critical embedded systems where deterministic access times and high reliability are paramount. The family typically offers various speed grades and organization options to fit diverse memory density and latency requirements in networking and industrial control sectors.

Memory IC Replacement Considerations

Check Renesas datasheets for pin-compatible alternatives within the 7027S series with different speed grades. Verify if the 709279 series serves as a functional equivalent with similar synchronous dual-port characteristics. Ensure any substitute maintains the 100-TQFP package and 5V operating voltage specifications.
