7025S35PF8/S2756

Memory IC Overview

The Renesas Electronics Corporation 7025S35PF8/S2756 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 128 kilobits, organized as 8K words by 16 bits. The device features asynchronous parallel interface operation with an access time and write cycle time of 35 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 100-TQFP package measuring 14x14 mm. The component is classified as obsolete and no longer manufactured.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems
• Asynchronous parallel interface for flexible integration into standard digital logic designs
• Volatile memory technology maintaining data integrity during active power supply

Memory IC Applications

• High-speed data buffering between asynchronous system components

• Data storage in industrial control systems requiring rapid read/write cycles

Memory IC Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Verification of authenticity is critical when sourcing remaining stock from third-party distributors. Confirm the specific suffix matches the required package and temperature grade. Check for RoHS compliance status, as older revisions may not meet current environmental regulations. Validate supplier authorization to mitigate counterfeit risks associated with end-of-life parts.

Memory IC Selection Notes

Designers should evaluate the 7025L series as potential upgrades due to the discontinuation of the S-series. Verify that the replacement part maintains compatibility with the existing 100-TQFP footprint and electrical specifications. Assess whether the target application requires the specific 35ns timing characteristics or can accommodate faster alternatives. Ensure the new selection supports the necessary operating voltage and temperature ranges for the intended environment.

Memory IC Part Context

The 7025S35PF8 belongs to the Renesas 7025S family of dual-port SRAMs. This series is designed for applications requiring high-performance data sharing between multiple masters. The PF8 suffix indicates a specific commercial temperature grade and tape-and-reel packaging configuration. The device utilizes standard CMOS technology to achieve low power consumption relative to its performance class.

Memory IC Replacement Considerations

The 7025L20PFGI8 is listed as an upgrade alternative. Verify pinout compatibility and electrical parameter alignment before substitution.
