Ordering and board constraints

This reference identifies a base device. Package, speed grade, temperature, qualification and packing suffixes have not been inferred.

  • Check total output current and power-on pin state.
  • Choose pull-ups using bus capacitance and logic voltage.
  • Confirm current availability and lifecycle for the complete code before procurement.
  • Review pinout, electrical conditions and the exact document revision before PCB release.

Prepare a complete request

Include the full ordering code, quantity, delivery requirement and traceability needs. For an assembled board, include BOM revision, programming and test scope.
