Memory IC Procurement Notes

Verify the exact suffix against manufacturer documentation, as variations such as -3DBLI or -3DBL may indicate specific packaging or temperature grades. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly. Ensure ordering specifications match the required lead times and factory production cycles provided by the supplier.

Memory IC Selection Notes

Select this component when a 1 Gbit density with a 16-bit interface is required for DDR2 compliant designs. Consider the 84-ball BGA footprint constraints and the 0°C to +85°C operating temperature range. Evaluate system timing requirements against the 450 ps access time specification to ensure compatibility with the target processor or controller.
