Note 1. The values are reference values when the 4-layer board is used. Thermal resistance depends on the number of layers or size of the

board. For details, refer to the JEDEC standards.

Note 1. The values are guaranteed by design.

Note 2. LDO and Leak are internal voltage regulator’s current and MCU’s leakage current.

It is selected according to the temperature of Ta.

Note 3. Δ(Tj-Ta) = 20 °C is considered to measure the current.

Note 4. To determine the current consumption per channel, group or unit, divide Current [mA] by the number of channels, groups or units.

Table 2.13 shows the outline of operation for each unit.
