Memory IC Procurement Notes

Verify the specific ordering suffix 'TR' indicates tape and reel packaging when sourcing this component. Confirm that the '-12J' designation matches the required DDR3L-1600 speed bin and industrial plus temperature rating (-40°C to 105°C). Ensure compatibility with the 96-ball VFBGA footprint during procurement planning.

Memory IC Selection Notes

Select this part for designs requiring a 16-bit wide DDR3L interface with high-speed capabilities up to 1600 MT/s. The -12J grade is suitable for applications demanding operation across a wider temperature range than standard industrial parts. Consider the VFBGA-96 package dimensions for PCB layout constraints.
