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. RA4M2 Datasheet 2. Electrical Characteristics R01DS0367EJ0140 Rev.1.40 May 9, 2025 Page 32 of 93 |
