Caution
When using the X1 oscillator and XT1 oscillator, wire as follows in the area enclosed by the
broken lines in the Figures 5-11 and 5-12 to avoid an adverse effect from wiring capacitance.
• Keep the wiring length as short as possible.
• Do not cross the wiring with the other signal lines. Do not route the wiring near a signal
• Always make the ground point of the oscillator capacitor the same potential as V
• Do not fetch signals from the oscillator.
• Pins and circuit boards include parasitic capacitance.
• Configure the circuit of the circuit board, using material with little wiring resistance.
• Place a ground pattern that has the same potential as V
• Be sure that the signal lines between the XT1 and XT2 pins, and the resonators do not cross
• The impedance between the XT1 and XT2 pins may drop and oscillation may be disturbed
• When coating the circuit board, use material that does not cause capacitance or leakage
