Memory IC Procurement Notes

Verify the specific suffix BCN against official datasheets to confirm package type and temperature grade. Confirm RoHS compliance status through manufacturer documentation. Check for any end-of-life notifications or discontinuation notices prior to finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 4 Gbit capacity with a 16-bit interface is required for DDR4 systems. Ensure the design accommodates the 96-ball FBGA footprint. Verify that the application environment remains within the 0°C to +95°C operational temperature limits defined for the extended commercial grade.

Memory IC Part Context

This part belongs to the AS4C256M16D4A series of 4 Gbit DDR4 SDRAMs. It shares architectural similarities with other members like the AS4C256M16D4A-75BIN but differs in speed grade and package variant. The series targets high-density memory applications requiring low power consumption and high bandwidth.

Memory IC Replacement Considerations

AS4C256M16D4A-75BIN offers similar capacity and interface but operates at a lower 1.333 GHz speed grade.
