*3: V

should not exceed Vcc + 0.3 V. V
I
must not exceed the rating voltage. However, if the maximum
current to/from an input is limited by some means with external components, the I
CLAMP
rating supersedes
the V
I
rating.
*4: Applicable pins: P10 to P15, PF0, PF1 (Inapplicable pins: PG1, PG2)
Use within recommended operating conditions.
Use at DC voltage (current).
+
B signal is an input signal that exceeds V
CC
voltage. The
+
B signal should always be applied 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 affects
other devices.
Note that if the
+
B signal is inputted when the microcontroller power supply 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 power 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 other than the A/D input pins (LCD drive 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.
