Memory IC Procurement Notes

Verify the specific ordering suffix matches the required voltage and interface configuration. Confirm that the component meets RoHS compliance standards for lead-free and halogen-free requirements. Ensure the selected part number aligns with the intended operating temperature range and package dimensions for your design.

Memory IC Selection Notes

Select this model when a 1.8V supply and 16-bit bus width are required for the 4 Gbit density level. Consider the 63-ball FBGA footprint constraints and verify compatibility with existing controller interfaces supporting ONFI 1.0 specifications. Evaluate the multi-plane operation capabilities if higher throughput is necessary.

Memory IC Part Context

This component belongs to the JSC NAND Series, which offers densities from 1 Gbit to 8 Gbit. The series is designed for solid-state mass storage markets, providing pinout compatibility across densities to facilitate easy migration. It features an on-chip Program/Erase Controller to automate internal verification and margining processes.

Memory IC Replacement Considerations

Pinout compatibility exists across all densities within the same series. Verify that any substitute maintains the 1.8V supply requirement and 16-bit interface width. Check that the replacement supports the same ONFI command set and package dimensions.
