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 specific project standards, as this variant may not meet current environmental directives. Validate package integrity upon receipt, ensuring the TQFP-64 leads are undamaged. Check datasheet revisions for any pinout or electrical characteristic updates prior to final design integration.

Memory IC Selection Notes

Select this component when dual-port functionality is required for shared memory access between multiple controllers. Ensure the system operates within the specified 4.5 V to 5.5 V voltage range. Consider the 35 ns access speed against system timing requirements. Verify that the TQFP-64 package fits the PCB layout constraints. Evaluate thermal management needs based on the 110 mA maximum current draw at the intended operating temperature.

Memory IC Part Context

This part belongs to the Renesas 7130 series of dual-port SRAMs. It is manufactured by Renesas Electronics Corporation, formerly IDT. The 7130SA35TF is a specific variant within the 7130 family, distinguished by its 35 ns speed grade and 5V operation. It serves as a high-speed memory solution for applications requiring concurrent read/write access from two distinct masters.

Memory IC Replacement Considerations

The 7130SA35TF is listed as obsolete. Potential substitutes include other Renesas dual-port SRAMs with similar specifications, such as the 71321SA35TFG for larger capacity or different packages. Cross-reference pinouts and electrical characteristics carefully before substitution.
