Memory IC Applications

• Embedded systems requiring shared memory resources
• Industrial control applications with dual-processor architectures
• Telecommunications equipment utilizing asynchronous memory interfaces

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance requirements against project specifications, as this specific variant may not meet current environmental directives. Validate package integrity upon receipt, ensuring the PLCC-68 leads are undamaged. Cross-reference part numbers with official Renesas documentation to avoid counterfeit substitutions.

Memory IC Selection Notes

Select this component when a 256 kbit dual-port SRAM with 35 ns access speed is required for 5V logic systems. Ensure the design accommodates the 68-PLCC surface-mount footprint and thermal constraints within the commercial temperature range. Verify that the parallel interface signals align with the target processor's memory controller capabilities before finalizing the bill of materials.

Memory IC Part Context

This device belongs to the Renesas 7007S35 series of dual-port SRAMs. It serves as a successor to legacy IDT products, maintaining pin compatibility and functional equivalence. The series provides reliable non-volatile-free storage solutions for applications needing high-speed data exchange between multiple masters without complex arbitration logic.

Memory IC Replacement Considerations

Official substitute part numbers include IDT7007S35J8 and IDT7007S35JI8. These variants offer identical electrical characteristics and pinouts, facilitating drop-in replacements in existing designs.
