■ ELECTRICAL CHARACTERISTICS
1.
Absolute Maximum Ratings
*1 : This parameter is based on VSS
= AVSS = 0.0 V.
*2 : AVCC must never exceed VCC when the power is turned on.
*3 : VI and VO must never exceed VCC + 0.3 V. However if the maximum current to/from an input is limited by some
means with external components, the ICLAMP rating supersedes the VI rating.
*4 : The maximum output current is a peak value for a corresponding pin.
*5 :
Applicable to pins: P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40 to P47, P50, P51, P80 to P87.
Use within recommended operating conditions.
Use at DC voltage (current).
The +B signal is an input signal exceeding VCC 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 Vcc pin, and this may affect
other devices.
