*6 : Average total output current is defined as the value of the average current flowing over 100 ms at all of the
corresponding pins. The “average value” can be calculated from the formula of “operating current” times
“ operating factor”.
*7 :
Applicable to pins : P00 to P07, P10 to P15, P50 to P57, P70 to P77, P80 to P87
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 V
CC
pin, and this may affect
other devices.
Note that if a
+
B signal is input when the microcontroller current is off (not fixed at 0 V) , the power supply
is provided from the pins, so that incomplete operation may result.
Note that if the
+
B input is applied during power-on, the power supply is provided from the pins and the
resulting supply voltage may not be sufficient to operate the power-on reset.
Care must be taken not to leave the
+
B input pin open.
Note that analog system input/output pins (LCD drive pins, comparator input pins, etc.) cannot accept
+
B
signal input.
Sample recommended circuits :
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.
