7.10.2.2.2 Power-Down Sequencing

Table 7-5 and Figure 7-6 describes the device power-down sequencing.

Note

The power supply sequencing requirements defined in this section does not include entry or exit

from low power modes. See Section 7.10.2.2.3, Partial IO Power Sequencing for more information on

power supply sequence requirements when entering or exiting low power modes.

(1)

VDDSHV_CANUART, VDDSHV_MCU, and VDDSHVx [x=0-3] when operating at 3.3V.

(2)

VDDSHV_CANUART, VDDSHV_MCU, and VDDSHVx [x=0-3] when operating at 1.8V.

(3)

VDDSHV4, VDDSHV5, and VDDSHV6 were designed to support power-up, power-down, or dynamic voltage change without any

dependency on other power rails. This capability is required to support UHS-I SD Cards.

(4)

VDD_CANUART when connected to an always-on power source for Partial IO low power mode.

(5)

VDD_CANUART, VDD_CORE, VDDA_CORE_CSIRX0, VDDA_CORE_USB0, and VDDA_DDR_PLL0 when operating at 0.75V

(6)

VDD_CANUART, VDD_CORE, VDDA_CORE_CSIRX0, VDDA_CORE_USB0, and VDDA_DDR_PLL0 when operating at 0.85V
