*1 : This parameter is based on VSS = PLLVSS = 0 V.

*2 : Note that analog power supply voltage and input voltage do not exceed VDDE + 0.3 V at power on.

*3 : The maximum output current is the peak value for a single pin.

*4 : The average output current 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.

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.

Notes : • Apply equal potential to all of the VDDE pins.

Apply equal potential to all of the VDDI pins.

Fix all of the VSS pins at 0 V.

Leave N.C. pins open.
