2. Electrical Characteristics

Figure 2.18

Voltage dependency in subosc-speed mode (reference data)

Note 1.

Supply current values do not include output charge/discharge current from all pins. The values apply when internal pull-up

MOSs are in the off state.

Note 2.

The IWDT and LVD are not operating.

Note 3.

Includes the current of sub-oscillation circuit or low-speed on-chip oscillator.

Note 4.

VCC = 3.3 V.

Note 1. All peripheral operations except any BGO operation are operating normally. This is the average of the

actual measurements of the sample cores during product evaluation.

Note 2. All peripheral operations except any BGO operation are operating at maximum. This is the average of the

actual measurements for the upper-limit samples during product evaluation.
