Memory IC Procurement Notes

Verify the specific speed grade and package configuration against the official datasheet before ordering. Confirm that the automotive temperature rating aligns with your system's operational environment. Ensure power supply sequencing meets initialization requirements to prevent undefined states.

Memory IC Selection Notes

Select this component when a 256 Mbit capacity with a 16-bit interface is required. Consider the 60-ball FBGA package constraints for PCB layout. Verify compatibility with SSTL_2 signaling standards in the host system design.

Memory IC Part Context

This part belongs to the IS43/46R16160D series of DDR SDRAMs. The 'IS46' prefix indicates a 16-bit organization variant within the family. The '-5B' suffix denotes the -5 speed grade and BGA package type. The 'LA1' suffix specifies the lead-free automotive qualification.

Memory IC Replacement Considerations

Check for other speed grades within the same package family if timing requirements differ. Verify pinout compatibility before substituting with similar density parts.
