■ ELECTRICAL CHARACTERISTICS
1.
Absolute Maximum Ratings
*1 : This parameter is based on VSS
= AVSS = 0.0 V.
*2 : AVCC and AVRH must not exceed VCC. Also, AVRH must not exceed AVCC.
*3 : VI and V0 must not exceed VCC
+ 0.3 V. However, if the maximum current to/from and input is limited by some
means with external components, the ICLAMP rating supersedes the VI rating.
*4 : Maximum output current is defined as the peak value for one of the corresponding pins.
*5 : Average output current is defined as the average current flow in a 100 ms interval at one of the corresponding
pins.
*6 : Average total output current is defined as the average current flow in a 100 ms interval at all corresponding pins.
*7 :
Applicable to pins : P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40 to P47, P50 to P57, P60 to P67,
P70 to P77, P80 to P87, P90 to P97, PA0 to PA3
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.
