Note 1: Referenced to VCC1=AVCC=VREF=3.3 to 5.5V, VSS=AVSS=0V at Topr = -20 to 85
°C / -40 to 85 °C unless otherwise
specified.
Note 2: If VCC1 > VCC2, do not use AN00 to AN07 and AN20 to AN27 as analog input pins.
Note 3: AD operation clock frequency (AD frequency) must be 10 MHz or less. And divide the fAD if VCC1 is less than 4.2V,
and make AD frequency equal to or lower than fAD/2.
Note 4: A case without sample & hold function turn AD frequency into 250 kHz or more in addition to a limit of Note 3.
A case with sample & hold function turn AD frequency into 1MHz or more in addition to a limit of Note 3.

Note 1: Referenced to VCC1=VREF=3.3 to 5.5V, VSS=AVSS=0V at Topr = -20 to 85
°C / -40 to 85 °C unless otherwise
specified.
Note 2: This applies when using one D-A converter, with the D-A register for the unused D-A converter set to “0016”. The
A-D converter’s ladder resistance is not included. Also, when D-A register contents are not “0016”, the current
IVREF always flows even though Vref may have been set to be unconnected by the A-D control register.
