Memory IC Procurement Notes

Verify the specific suffix J8 against official Renesas documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check current production status as legacy components may have limited availability or obsolescence notices. Ensure voltage levels match your system design before procurement.

Memory IC Selection Notes

Select this component when dual-port functionality is required for shared memory access between distinct logic blocks. The 12 ns speed class offers a balance between performance and power consumption compared to faster variants. Consider the 84-PLCC package constraints regarding board space and thermal management. Verify that the 5V operating voltage aligns with your system's power distribution network.

Memory IC Part Context

This part belongs to the Renesas 7025L series of dual-port SRAMs, which are widely used in embedded systems. The series typically includes variations with different access speeds and package options. These devices are engineered for robustness in demanding electronic environments, providing non-volatile-like reliability for volatile memory operations through their stable CMOS technology.

Memory IC Replacement Considerations

Official substitutes include other members of the 7025L series with compatible pinouts and electrical characteristics. Verify that any replacement maintains the same 8Kx16 organization and dual-port capability. Cross-reference datasheets to ensure identical voltage and temperature specifications.
