Memory IC Procurement Notes

Verify the specific suffix 'I' confirms industrial temperature rating compliance (-40°C to +85°C). Confirm the 165-bump BGA package dimensions match the target PCB layout constraints. Ensure power supply designs accommodate the specified 1.7 V to 1.9 V core voltage range and peak current requirements during active operation cycles.

Memory IC Selection Notes

Select this component when a 36-bit wide data path is required for parallel processing applications. The 333 MHz speed grade suits high-bandwidth interfaces where pipeline coherence is critical. Consider the 165-bump BGA form factor for space-constrained designs needing robust surface-mount assembly. Verify compatibility with existing JEDEC-standard pinout implementations in the system architecture.
