Memory IC Applications

• High-speed data buffering in telecommunications equipment.

Memory IC Procurement Notes

This component has reached end-of-life status and is no longer manufactured by Renesas Electronics Corporation. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Procurement should prioritize the manufacturer-recommended replacement part number 7024L20G to ensure long-term supply chain stability and compatibility with existing designs.

Memory IC Selection Notes

Designers requiring this specific memory configuration must account for the discontinuation status when planning production lifecycles. The primary selection criterion involves evaluating the recommended substitute, 7024L20G, which offers faster performance metrics and extended temperature ranges. Compatibility checks regarding pinout and electrical specifications are essential before transitioning to alternative components.

Memory IC Part Context

The 7024S55G belongs to the Renesas 7024S/L series of dual-port SRAMs. This family is designed for applications requiring high-speed data exchange between asynchronous systems. The specific model represents a mid-range speed variant within the series, utilizing standard CMOS technology for low power consumption relative to its performance class.

Memory IC Replacement Considerations

The manufacturer recommends the 7024L20G as the direct replacement. Designers should verify that the improved speed and temperature range of the substitute do not introduce signal integrity issues in existing layouts.
