Electrical Characteristics
32.1
Absolute Maximum Ratings
Caution: Permanent damage to the MCU may result if absolute maximum ratings are exceeded.
To preclude malfunctions due to noise interference, insert capacitors with high frequency characteristics between the VCC and
VSS pins, and between the AVCC0 and AVSS0 pins. Place capacitors with values of about 0.1 μF as close as possible to every
power supply pin and use the shortest and widest possible traces for the wiring.
Connect the VCL pin to a VSS pin via a 4.7-μF capacitor. The capacitor must be placed close to the pin.
Do not input signals to ports other than 5-V tolerant ports while the device is not powered.
The current injection that results from input of such a signal may cause malfunction and the abnormal current that passes in the
device at this time may cause degradation of internal elements.
Even if –0.3 to +6.5 V is input to 5-V tolerant ports, it will not cause problems such as damage to the MCU.

Recommended operating conditions
Note 1. AVCC0 and VCC can be set individually within the operating range.
Note 2. When powering on the VCC and AVCC0 pins, power them on at the same time or the VCC pin first and then the AVCC0 pin.
Note 1. Use a multilayer ceramic capacitor whose nominal capacitance is 4.7 µF and a capacitance tolerance is ±30% or better.
