Memory IC Procurement Notes

Verify the specific suffix BLI against the manufacturer's current datasheet to confirm pinout and packaging details. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Check for end-of-life notifications or obsolescence warnings directly from ISSI documentation before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 32 Mbit density with a 16-bit data bus width is required. Ensure the design accommodates the 54-ball TFBGA footprint and the specified voltage levels. Verify that the system controller supports the necessary SDRAM initialization sequences and command protocols defined in the specification.

Memory IC Part Context

This part belongs to the IS42SM16200 series of low-power mobile SDRAMs. It shares architectural similarities with the IS42RM and IS42VM variants, differing primarily in environmental ratings and specific feature sets. The series targets applications demanding high bandwidth within strict power constraints.

Memory IC Replacement Considerations

Consult official ISSI documentation for verified substitute part numbers. Cross-referencing requires matching organization, speed grade, and package type.
