Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the revision level against the latest manufacturer datasheet to ensure compatibility with existing designs. Check for any product change notifications or end-of-life status updates prior to finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 128Mb density with an 8-bit data bus width is required. Ensure the system design accommodates the 54-pin TSOP II physical footprint. Verify that the operating environment falls within the specified commercial or industrial temperature limits defined for the specific grade.

Memory IC Part Context

This part belongs to the IS42/45S81600F series of high-speed CMOS dynamic random-access memories. It is internally configured as a quad-bank DRAM designed for 3.3V memory systems. The series supports various burst configurations and includes features like auto-precharge and burst termination for flexible system integration.

Memory IC Replacement Considerations

Direct substitutes include other parts from the IS42S81600F family with matching speed grades and packages. Cross-vendor replacements must match the 128Mb density, 8-bit width, and 54-pin TSOP II form factor while maintaining LVTTL interface compatibility.
