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
temperature. 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”.
