Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range (-40°C to +85°C) against the manufacturer's official datasheet. Confirm that the TQFP-100 package matches the target PCB footprint design. Ensure voltage levels align with the 2.3 V to 3.6 V operational specifications before integration.

Memory IC Selection Notes

Select this component when a 72 Mbit capacity with 36-bit width is required for high-frequency parallel interfaces. The 250 MHz speed and 6.5 ns access time suit demanding throughput applications. Consider the TQFP-100 package constraints and industrial temperature rating during system thermal and mechanical design phases.

Memory IC Part Context
