Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) distinct from commercial variants. Confirm the TQFP-100 package type matches the target PCB footprint. Ensure the 250 MHz speed grade aligns with system timing requirements. Check RoHS compliance status as indicated in official documentation.

Memory IC Selection Notes

Select this component when a 250 MHz synchronous SRAM with an 18-bit data width is required. The industrial temperature rating makes it suitable for harsh environments compared to commercial options. Consider the TQFP-100 package constraints for board space. Verify that the 2.5 V or 3.3 V I/O supply matches the host processor voltage levels.
