Memory IC Procurement Notes

Verify current availability status as this component may be subject to discontinuation or limited stock. Confirm RoHS compliance requirements against specific project standards, as older variants may not meet current environmental directives. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference datasheet revisions to confirm pinout and electrical characteristics match design specifications before procurement.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent processor and peripheral access. Compare access times and package options against alternative parts in the 7025 series. Evaluate thermal performance within the specified operating temperature range. Consider system voltage compatibility with the 4.5 V to 5.5 V supply requirement. Assess physical footprint constraints relative to the 84-PLCC package dimensions.

Memory IC Part Context

This part belongs to the Renesas 7025 family of dual-port SRAMs, designed for applications needing independent port access. The 'L' suffix typically denotes lower power consumption compared to standard variants. The '55' indicates the 55 ns access speed class. The 'JI' suffix specifies the 84-PLCC package and industrial temperature rating. This family serves as a bridge between standard single-port memories and complex FIFO buffers.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers for the 7025L55JI were not identified in the provided source material. Verify compatibility with any potential alternatives by comparing pin configurations, electrical parameters, and functional behavior against the original datasheet specifications.
