Memory IC Procurement Notes

Verify the specific suffix 'Q' against official datasheets to confirm package type and temperature range. Ensure compatibility with DDR2 controller specifications regarding voltage levels and timing parameters. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Memory IC Selection Notes

Select this component when a 64M x 16 configuration is required with 400 MHz operation capability. Compare access times and power consumption metrics against alternative DDR2 devices. Ensure the FBGA footprint matches the target PCB layout constraints and thermal management requirements.

Memory IC Part Context

This part belongs to the EM68C series of DDR2 SDRAMs from Etron Technology. It shares architectural similarities with other members like the EM68C16CWQE-25H but differs in package and potentially qualification grades. The series targets applications demanding synchronous dynamic random-access memory with double data rate capabilities.

Memory IC Replacement Considerations

Direct substitutes include the EM68C16CWQE-25H and EM68C16CWQG-18H from the same manufacturer. Verify pinout compatibility and electrical characteristics before substitution. Cross-reference with Alliance Semiconductor AS4C64M16D2-25BCN for functional equivalence.
