2. Electrical Characteristics

Caution: To protect the MCU’s reliability, the output current values should not exceed the values in Table 2.8.

Note 1. This is the value when normal driving ability is set with a pin for which normal driving ability is selectable.

Note 2. This is the value when high driving ability is set with a pin for which normal driving ability is selectable or the value of the pin to

which high driving ability is fixed.

Note 3. This is the value when high-speed interface high-driving ability is set with a pin for which high-speed interface high-driving ability

is selectable.

Note:

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.

Permissible Output Currents

Conditions: VCC = AVCC0 = AVCC1 = VCC_USB = VBATT = 2.7 to 3.6 V, 2.7 V ≤ VREFH0 ≤ AVCC0,

VSS = AVSS0 = AVSS1 = VREFL0 = VSS_USB = 0 V,
