*5 : Average output current is defined as the average value of the current flowing through any one of the
corresponding pins within a period of 100 ms. The “average value” can be calculated by multiplying the
“operating current” by the “operating factor”.
*6 : Average total output current is defined as the average value of the current flowing through all of the
corresponding pins within a period of 100 ms. The “average value” can be calculated by multiplying the
“operating current” by the “ operating factor”.
*7 :
Applicable to pins: P10 to P15,P50 to P57,P60 to P67,P70 to P77,P80 to P87,PC0 to PC7,PD0 to PD6,
PE0 to PE2
Use within recommended operating conditions.
Use at DC voltage (current) .
The +B signal should always be applied with a limiting resistance placed between the +B signal and the
microcontroller.
The value of the limiting resistance should be set so that when the +B signal is applied, the input current to
the microcontroller pin does not exceed rated values, either instantaneously or for prolonged periods.
Note that when the microcontroller drive current is low, such as in the power saving modes, the +B input
potential may pass through the protective diode and increase the potential at the VCC pin, and this may affect
other devices.
Note that if a +B signal is input when the microcontroller power supply is off (not fixed at 0 V) , the
microcontroller may partially malfunction on power supplied through the +B signal pin.
Note that if the +B input is applied during power-on, the power supply voltage may reach a level such that
the power-on reset does not function due to the power supplied from the +B signal.
Care must be taken not to leave +B input pins open.
Note that analog system input/output pins (LCD drive pins, comparator input pins, etc.) cannot accept
+B signal inputs.
Sample recommended circuit :
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.
