29. Electrical Characteristics
[Operating precautions]
1. When the A/D converter is not used (including during standby), do not leave the AVCC, AVref, and AVSS pins open.
2. The current consumption is measured when VIHmin = VCC – 0.3 V/PVCC – 0.3 V, VIL = 0.3 V, with all output pins
unloaded.
3. The guaranteed operating range of power supply PVCC1 in the MCU expanded modes is only PVCC1 = 3.3 V ±0.3 V. Do
not use a voltage outside this range.
4. The guaranteed operating range of power supply PVCC1 in MCU single-chip mode is only PVCC1 = 5.0 V ±0.5 V. Do
not use a voltage outside this range.
Table 29.5 Permitted Output Current Values
Conditions: VCC = PLLVCC = 3.3 V ±0.3 V, PVCC1 = 5.0 V ±0.5 V/3.3 V ±0.3 V,
PVCC2 = 5.0 V ±0.5 V, AVCC = 5.0 V ±0.5 V, AVref = 4.5V to AVCC,
VSS = PLLVSS = AVSS = 0 V, Ta = –40°C to 125°C.
When PVCC1 = 3.3 V ±0.3 V, VCC = PVCC1.
When writing or erasing on-chip flash memory, Ta = –40°C to 85°C.
