Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure compatibility with existing PCB footprints and thermal management solutions. Review datasheet specifications for electrical characteristics prior to integration into final designs.

Selection Notes

Select this component for applications requiring synchronous FIFO functionality with 8K x 9 organization. Consider the 32-TQFP package constraints for board layout. Evaluate power consumption and thermal dissipation capabilities within the specified voltage and temperature ranges. Compare performance metrics against alternative memory solutions if higher density or different interface types are required.
