Procurement Notes

Verify the specific suffix against official documentation, as the provided model lacks the 'I8' designation found in common variants. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure the procurement channel supplies genuine Renesas components to avoid counterfeit risks associated with obsolete or legacy memory parts.

Selection Notes

Select this component when a 36-bit data width is required for system bus compatibility. The 10 ns access time suits applications demanding moderate synchronization speeds. Consider the TQFP-100 package constraints for PCB layout. Verify that the 66 MHz operational limit aligns with the host processor's clock requirements.
