MB89920 Series

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.
