(1) Current ratings specified in this table are worst-case estimates. Actual application power supply estimates could be lower. For more
information, see the AM335x Power Consumption Summary application report (SPRABN5).
(2) VDD_MPU is merged with VDD_CORE and is not available separately on the ZCE package. The maximum current rating for
VDD_CORE on the ZCE package is the sum of VDD_CORE and VDD_MPU shown in this table.
(3) This supply is sourced from an internal LDO when RTC_KALDO_ENn is low. If RTC_KALDO_ENn is high, this supply must be sourced
from an external power supply.
(4) Not available on the ZCE package.
(5) VDDSHV1 and VDDSHV2 are merged in the ZCE package. The maximum current rating for VDDSHV1 on the ZCE package is the sum
of VDDSHV1 and VDDSHV2 shown in this table.
