Applications, Implementation, and Layout

Figure 7-9 shows a split configuration where VDDSHV[0, 1, 2, 5, 8] and VDDSHV0_WKUP are configured

for 3.3 V operation, while VDDSHV[3, 4, 6, 7] and VDDSHV[2:1]_WKUP are configured for 1.8 V

operation. Note the colors indicate rails that are tied to the same source.

Figure 7-9. VDDSHV[8:0] and VDDSHV[2:0]_WKUP supplies configured for combination of 1.8 V or 3.3 V

operation

(1) VDDSHV6 and VDDSHV7 can only operate at 1.8 V.

(2) When any of the VDDSHV[8:0] or VDDSHV[2:0]_WKUP are configured for 1.8 V operation, the corresponding VDDS[8:0] or

VDDS[2:0]_WKUP must be connected to their respective VDDSHV[8:0] or VDDSHV[2:0]_WKUP power supply.

Figure 7-10 illustrates the system configuration when VDDSHV6 or VDDSHV7 is used as the MMCSD

supply.
