Memory IC Procurement Notes

Verify the specific suffix BLI confirms the 48-ball BGA package and industrial temperature rating. Ensure the EALL designation matches the required 1.7V to 1.95V voltage range for your target circuit. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when a compact 8 Mbit storage solution is needed with low power consumption requirements. The 70 ns speed suits moderate performance embedded applications. Consider the 48-ball BGA footprint constraints during PCB layout planning. Verify that the 1.7V minimum supply voltage aligns with the system's power management architecture.

Memory IC Part Context

This part belongs to the IS66WV51216EALL series of pseudo SRAM devices from ISSI. These components are designed as drop-in replacements for standard SRAMs while offering higher density in smaller packages. The series targets applications where board space is limited and power efficiency is critical for battery-operated or thermally constrained systems.

Memory IC Replacement Considerations

Check pinout compatibility with existing designs. Verify voltage level matching between address/data lines and the host processor. Ensure the new component supports the same asynchronous timing requirements.
