Part Datasheet Review and Mismatch Check

flux

I’ll populate terminal metadata from the existing ball names: grouping pins by LPDDR channel/function, adding concise datasheet-style descriptions, section labels, and symbol orientation consistently across all 200 terminals.

flux

Signal metadata is populated for the data, strobe, command/address, clock, control, power, ground, reserved, and calibration groups. I’m doing a quick coverage check now.

Completed the metadata population pass for the 200-terminal LPDDR4/LPDDR4X part.
Updated:
  • Pin Description
  • Pin Group
  • Pin Orientation
  • Section
Coverage included:
  • DQ data pins
  • DMI pins
  • DQS true/complement strobes
  • CA command/address pins
  • CK true/complement clocks
  • CKE, CS, ODT_CA, RESET_n control pins
  • VDD1, VDD2, VDDQ power pins
  • VSS ground pins
  • ZQ calibration pins
  • NC and DNU reserved/no-connect pins
I also preserved the earlier caution that VS appears likely intended to be VSS, but left the designator unchanged and marked it as a ground-related review item rather than silently renaming it.
