Caution 1. When using the X1 oscillator and XT1 oscillator, wire as follows in the area enclosed by the
broken lines in the Figures 7-13 and 7-14 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 line
• Always make the ground point of the oscillator capacitor the same potential as V
• Do not fetch signals from the oscillator.
The XT1 oscillator is a circuit with low amplification in order to achieve low-power consumption.
Note the following points when designing the circuit.
• Pins and circuit boards include parasitic capacitance. Therefore, perform oscillation evaluation
• When using the ultra-low power consumption oscillation (AMPHS1 = 1) as the mode of the XT1
• Make the wiring between the XT1 and XT2 pins and the resonators as short as possible, and
• 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 due
• When coating the circuit board, use material that does not cause capacitance or leakage
