Procurement Notes

Verify current availability status as the manufacturer has issued product change notices regarding this component. Confirm RoHS compliance details and moisture sensitivity level requirements before integration into manufacturing processes. Ensure that the specific package variant matches the design footprint constraints. Check for any recent obsolescence announcements or recommended replacement parts from the supplier.

Selection Notes

Select this component when a wide 36-bit data path is required for synchronous memory interfaces. It is suitable for designs needing 133 MHz operation speeds within the commercial/industrial temperature range. Consider the physical dimensions of the 165-CABGA package during PCB layout planning. Evaluate power consumption limits against the specified maximum current draw for thermal management purposes.

Part Context

This part belongs to the 71V65603 series of synchronous SRAMs designed for high-speed data processing.
