NOTES:
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.
2. If VCC1 > VCC2, do not use AN0_0 to AN0_7 and AN2_0 to AN2_7 as analog input pins.
3. AD operation clock frequency (øAD frequency) must be 12 MHz or less. And divide the fAD if VCC1 is less than 4.0V,
and øAD frequency into 10 MHz or less.
4. A case without sample & hold function turn øAD frequency into 250 kHz or more in addition to a limit of Note 3.
A case with sample & hold function turn øAD frequency into 1MHz or more in addition to a limit of Note 3.

NOTES:
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.
2. This applies when using one D-A converter, with the D-A register for the unused D-A converter set to “00h”. The A-D
converter’s ladder resistance is not included. Also, when D-A register contents are not “00h”, the current IVREF always
flows even though Vref may have been set to be unconnected by the A-D control register.
