Recommended Operating Conditions
NOTES:
1. When the A/D converter is used, refer to the recommended operating conditions of the A/D converter.
2. 12.5 MHz
<
f(X
IN
)
≤
16 MHz is not available in the frequency/2 mode.
3. The oscillation start voltage and the oscillation start time differ depending on factors such as the oscillator, circuit constants, and
operating temperature range. Note that oscillation start may be particularly difficult at low voltage when using a high-frequency
oscillator.
f: Oscillation frequency (1 MHz
≤
f(X
IN
)
≤
8 MHz) of oscillator. When the 8 MHz oscillation is used, assign “8” to “f”.
