7026S25G

Memory IC Overview

The Renesas Electronics Corporation 7026S25G is a high-speed, 256-kbit Dual-Port Static Random Access Memory (SRAM) organized as 16K words by 16 bits. It operates on a single 5V power supply with an access time of 25 ns and supports asynchronous parallel interfaces. The device features independent read/write ports for simultaneous data transfer without wait states. It includes automatic power-down capabilities controlled by chip enable signals to minimize standby current consumption. The component is designed for use in standalone dual-port configurations or master/slave arrangements within 32-bit or wider systems.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access from two distinct processors
• Automatic low-power standby mode activated via chip enable control
• Asynchronous parallel interface supporting standard TTL logic levels
• Capable of functioning as standalone memory or in master/slave combinations

Memory IC Applications

• High-performance computing systems requiring concurrent data access
• Network routers and switches utilizing packet buffering
• Industrial automation controllers managing real-time data streams
• Telecommunications equipment handling signal processing tasks

Memory IC Procurement Notes

Verify the specific suffix 'G' against official Renesas documentation to confirm compliance with lead-free manufacturing standards and RoHS directives. Confirm package type availability, as variations may exist between PLCC and other formats. Check for end-of-life notices or obsolescence warnings prior to procurement. Ensure compatibility with existing system voltage requirements and thermal management specifications.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent processor access without arbitration delays. Consider the 25 ns access speed for applications demanding rapid data retrieval. Evaluate the 84-pin PLCC package constraints regarding board space and thermal dissipation. Compare power consumption metrics against alternative SRAM families if energy efficiency is a critical design parameter.

Memory IC Part Context

The 7026 series represents a family of high-speed dual-port SRAMs designed for complex digital systems. These devices bridge the gap between fast microprocessors and large storage arrays. The 7026S25G specifically targets applications needing reliable, non-volatile-like performance with volatile speed. It serves as a key building block in embedded systems requiring robust data handling capabilities.

Memory IC Replacement Considerations

Consult official Renesas substitution guides for compatible alternatives. Verify pinout compatibility and electrical characteristics before replacing. Consider newer generations within the 7026 or 70V26 series for improved performance or packaging options.
