P90 to P97, PA0, and PA1
Use within recommended operating conditions.
Use at DC voltage (current)
The +B signal should always be applied by placing a limiting resistance 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 the 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) , power may
be supplied through the
+B pin, resulting in incomplete operation of the microcontroller.
Note that if the +B input is applied during power-on, the power supplied via the +B pin may result in the
supply voltage being insufficient to activate the power-on reset.
Care must be taken not to leave +B input pins open.
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.
