■ ELECTRICAL CHARACTERISTICS
1.
Absolute Maximum Ratings
*1 : The parameter is based on VSS
= AVSS10 = AVSS12 = 0 V.
*2 : Be careful not to exceed VCC
+ 0.3 V, for example, when the power is turned on.
Be careful to set AVCC10, AVCC12 equal VCC, for example, when the power is turned on.
*3 : The maximum output current is the peak value for a single pin.
*4 : The average output is the average current for a single pin over a period of 100 ms.
*5 : The total average output current is the average current for all pins over a period of 100 ms.
*6 : AVCC10 is the analog supply voltage for the 8/10-bit A/D converter, and AVCC12 is the analog supply voltage
for the 12-bit A/D converter.
*7 : AVRHn=AVRH0/AVRH1/AVRH2 are the analog reference voltage for the 8/10-bit A/D converter, and AVRH3/
AVRH4 are the analog reference voltage for the 12-bit A/D converter.
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.
