*2 : AVCC5 and AVRH5 must not exceed VDD5
+ 0.3 V.
*3 :
Use within recommended operating conditions.
Use with DC voltage (current).
+B signals are input signals that exceed the VDD5 voltage. +B signals should always be applied by
connecting a limiting resistor between the
+B signal and the microcontroller.
The value of the limiting resistor should be set so that the current input to the microcontroller pin does not
exceed the rated value at any time , either instantaneously or for an extended period, when the
+B signal
is input.
Note that when the microcontroller drive current is low, such as in the low power consumption modes, the
+B input potential can increase the potential at the power supply pin via a protective diode, possibly affecting
other devices.
Note that if the +B signal is input when the microcontroller is off (not fixed at 0 V), power is supplied through
the +B input pin; therefore, the microcontroller may partially operate.
Note that if the +B signal is input at power-on, since the power is supplied through the pin, the power-on reset
may not function in the power supply voltage.
Do not leave +B input pins open.
Example of recommended circuit :
*4 : Maximum output current is defined as the value of the peak current flowing through any one of the corresponding
pins.
*5 : Average output current is defined as the value of the average current flowing through any one of the
corresponding pins for a 100 ms period.
*6 : Total average output current is defined as the value of the average current flowing through all of the
corresponding pins for a 100 ms period.
WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current,
temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
