In non-security case, VDD_BAT can be connected to QVDD. 2 The fusebox read supply is connected to supply of the full speed USBPHY2_VDD. FUSE_VDD is only used for programming. It is recommended that FUSE_VDD be connected to ground when not being used for programming. See Table 6 for current parameters. 3 NVCC_DRYICE is supply output. A 0.1-μF external capacitor should be connected to it. Table 5. DC Operating Conditions (continued) Parameter Symbol Min. Typ. Max. Units |
