2. Recommended Operating Conditions
(VSS = 0.0 V)
*1: These values vary with the operating frequency, instruction cycle, and analog assurance range. See Figure 1
and “5. A/D Converter Electrical Characteristics”.
*2: VCC must not exceed V3.
Figure 1
Operating Voltage vs. Clock Operating Frequency
Figure 1 indicates the operating frequency of the external oscillator at an instruction cycle of 4/FC.
Since the operating voltage range is dependent on the instruction cycle, see minimum execution time if the
operating speed is switched using a gear.
