[1] Iload includes the pull-up resistor current via pin Vpu(3.3).
[2] In ‘suspend’ mode, the minimum voltage is 2.7 V.
[3] Maximum value is characterized only, not tested in production.
[4] Excluding any load current and Vpu(3.3)/Vsw source current to the 1.5 kΩ and 15 kΩ pull-up and pull-down resistors (200 μA typ.).
[5] When VCC(I/O) < 2.7 V, the minimum value for Vth(reg3.3)(present) is 2.0 V.
