Memory IC Procurement Notes

Verify the specific suffix 'TQI' confirms the 100-pin TQFP package and industrial temperature grade (-40°C to +85°C). Confirm that the '-200' designation matches the required 200 MHz operating speed. Ensure the datasheet specifies the correct I/O voltage compatibility (3.3V or 2.5V) for your system design. Check for RoHS compliance status if environmental regulations apply to your deployment.

Memory IC Selection Notes

Select this component when a wide 36-bit data path is required for high-throughput applications. The synchronous pipelined architecture suits designs needing predictable latency at high clock speeds. Consider the dual-voltage I/O capability if interfacing with mixed voltage logic families. Evaluate the 100-pin TQFP package constraints against available PCB real estate and thermal dissipation requirements.
