7025S25PF

Memory IC Overview

The Renesas 7025S25PF is an asynchronous 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 a parallel interface with a maximum access time of 25 nanoseconds and a write cycle time of 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm, designed for surface-mount installation.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at two distinct ports without conflict.
• Utilizes asynchronous logic control, eliminating the need for an external clock signal during operation.
• Maintains data integrity through volatile memory technology requiring continuous power supply.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Real-time data logging in industrial automation controllers

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence status. Confirm RoHS compliance requirements against specific project standards, as older batches may not meet current environmental directives. Validate package marking accuracy to distinguish from similar family members. Ensure proper handling procedures are followed given moisture sensitivity classification. Review technical documentation for any recent product discontinuance notifications or lifecycle changes before finalizing procurement plans.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent processor access. Choose based on the 25ns speed grade if higher performance variants like the 15ns model are unnecessary. Consider the 100-TQFP package for suitable PCB footprint constraints. Evaluate power consumption levels against system thermal limits. Compare organizational structure compatibility with existing memory maps in the target design architecture.

Memory IC Part Context

This part belongs to the Renesas 7025 series of high-performance dual-port SRAMs. It shares architectural similarities with other models in the lineup, differing primarily in access speed and packaging options. The series is designed for applications requiring fast, independent port access. Related parts include faster variants such as the 7025L15 and slower variants like the 7025S35, offering flexibility in performance-to-cost ratios for various system designs.

Memory IC Replacement Considerations

The manufacturer lists 7025L20PFGI as an upgrade replacement. Verify pinout compatibility and electrical specifications before substitution. Assess if the alternative package type meets mechanical constraints. Confirm that the replacement maintains required access times for system timing budgets.
