Memory IC Procurement Notes

Verify the specific suffix against official ISSI documentation to confirm package type and speed grade. Confirm availability status as distribution channels may list obsolete or discontinued variants. Ensure compatibility with existing board layouts regarding the BGA-90 footprint and pinout configuration before procurement.

Memory IC Selection Notes

Select this component when automotive environmental standards are required alongside high-density 32-bit data bus interfaces. Compare thermal performance and power consumption metrics against alternative packages if space allows. Validate that the 143 MHz operating speed meets system timing requirements for the target application.

Memory IC Part Context

This part belongs to the IS45S32400F series of automotive SDRAMs. It shares architectural similarities with other members but differs in physical package and specific speed binning. The F suffix typically denotes the BGA package variant within this product family line.

Memory IC Replacement Considerations

Check for direct substitutes such as the IS45S32400J series if TSOP-II packaging is acceptable. Verify electrical equivalence and pin compatibility before substituting with non-ISSI manufacturers.
