Memory IC Procurement Notes

Verify the specific suffix 'AT' to confirm the extended temperature rating (-40°C to 105°C) and TSOP II packaging. Ensure compatibility with LVTTL logic levels in the target circuit design. Confirm that the 54-pin footprint matches the PCB layout requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Memory IC Selection Notes

Select this component when an extended temperature range is required for SDRAM applications. The 16-bit data width suits systems needing higher bandwidth per cycle compared to 8-bit alternatives. The TSOP II package offers a balance between pin count and board space efficiency. Consider the 166 MHz speed limit when designing memory controllers for synchronous operations.

Memory IC Part Context

This part belongs to the NDS66P series of SDRAM devices from Insignis Technology Corporation. The series includes variants with different packages and temperature ratings, such as the IT version which typically covers commercial temperatures.
