Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance variations between manufacturing lots, as some records indicate non-compliance while others show adherence to RoHS3 standards. Validate the specific suffix against current datasheets to ensure correct package type and electrical specifications before integration into new designs.

Selection Notes

Select this component for applications demanding low-latency data retrieval and wide data bus widths. The 36-bit organization suits error correction code implementations. Ensure system power supplies maintain the required 3.3-volt tolerance. Consider the physical dimensions of the 165-CABGA package during PCB layout planning to accommodate thermal dissipation requirements.

Part Context
