Core AVDD1_18, AVDD2_18, AIF_VDDR_18, SGR_VDDR_18 1.8 180 ±5% 1
Core DVDD_11 (AIF_VDDD_11, AIF_VDDA_11, AIF_VDDT_11, SGR_VDDD_11, SGR_VDDA_11,SGR_VDDT_11) 1.1 1,450 ±5% 2


  • All 1.8V rails may be combined and all 1.1V rails may be combined; however, follow the filtering recommendations for each voltage rail in the C6474 Hardware Design Guide (spraaw7).
  • Consult the C6474 power spreadsheet for your exact power requirements.
  • DVDD18 voltage rail includes power required for external DDR2 memory.
