Memory IC Procurement Notes

Verify the specific suffix 'B' against official ISSI documentation to confirm exact electrical characteristics and pinout compatibility. Confirm that the 0°C to 70°C commercial temperature range meets system requirements. Ensure the 144-pin FCBGA footprint matches the PCB layout design before procurement.

Memory IC Selection Notes

Select this component when a 288 Mbit capacity with a 18-bit wide interface is required. The 300 MHz speed grade suits moderate-to-high bandwidth needs. Verify that the commercial temperature range and 1.8V supply voltage align with the target system's power and environmental constraints.

Memory IC Part Context

This part belongs to the IS49NLC18160 series of RLDRAM II devices from ISSI. It shares architectural similarities with variants like the -25BLI but differs in speed grade and temperature rating. The series targets applications requiring dense, fast volatile memory in compact packages.

Memory IC Replacement Considerations

Check for direct substitutes such as the IS49NLC18160-25BLI if higher speed (400 MHz) and industrial temperature ratings are acceptable. Verify pin compatibility and electrical specifications before substitution.
