Procurement Notes

Verify the current manufacturing status before procurement planning, as this specific part number may be discontinued or subject to end-of-life notices. Confirm that the 100-TQFP package dimensions and pinout are compatible with existing PCB footprints. Ensure that the 3.3V operating voltage aligns with the target system's power delivery network requirements. Check for available replacement components if active production is no longer guaranteed.

Selection Notes

Select this component when a 128K x 36 organization is required for synchronous memory applications. It is suitable for designs needing 100 MHz operation speeds with low latency. Consider the 100-pin TQFP package constraints for board space. Verify that the commercial temperature range meets the environmental conditions of the final assembly. Compare against newer series members if long-term availability is a primary constraint.
