Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required voltage and temperature grade. Confirm the x8 interface width aligns with the system bus design. Ensure the PCB footprint accommodates the 63-ball FBGA dimensions. Check RoHS compliance documentation if environmental regulations apply to the final assembly.

Memory IC Selection Notes

Select this component when a 1 Gbit density with x8 parallel interface is required. Choose this variant over x16 versions if the system design limits available data pins. Consider the 25 ns minimum sequential access speed for performance requirements. Verify that the 2.7 V to 3.6 V supply range matches the target platform's power rails.

Memory IC Part Context

This part belongs to the JSC NAND Series, which offers cost-effective solutions for mass storage markets. The series supports densities from 1 Gbit to 8 Gbit with pinout compatibility across densities. The device architecture allows migration between different capacities without rearranging the footprint. It integrates an on-chip Program/Erase Controller to automate memory management tasks.

Memory IC Replacement Considerations

Pinout compatibility exists within the JSC NAND Series for all densities. Verify that the replacement part maintains the same x8 interface and voltage specifications. Ensure the spare area size matches the existing controller configuration. Check if the new part supports the required ONFI version.
