Function
The value of the current that can be run per pin must satisfy the value of the
current per pin and the total value of the currents of all pins.
When using the X1 oscillator, wire as follows in the area enclosed by the broken
lines in the above figures 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 through which a high fluctuating
• Always make the ground point of the oscillator capacitor the same potential as
• Do not ground the capacitor to a ground pattern through which a high current
• Do not fetch signals from the oscillator.
Since the CPU is started by the internal high-speed oscillation clock after a reset
release, check the X1 clock oscillation stabilization time using the oscillation
stabilization time counter status register (OSTC) by the user. Determine the
oscillation stabilization time of the OSTC register and oscillation stabilization time
select register (OSTS) after sufficiently evaluating the oscillation stabilization time
with the resonator to be used.
When using the XT1 oscillator, wire as follows in the area enclosed by the broken
lines in the above figure 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 through which a high fluctuating
• Always make the ground point of the oscillator capacitor the same potential as
• Do not ground the capacitor to a ground pattern through which a high current
• Do not fetch signals from the oscillator.
The XT1 oscillator is designed as a low-amplitude circuit for reducing power
consumption, and is more prone to malfunction due to noise than the X1 oscillator.
Particular care is therefore required with the wiring method when the XT1 clock is
used.
The oscillator constants shown above are reference values based on evaluation in
a specific environment by the resonator manufacturer. If it is necessary to optimize
the oscillator characteristics in the actual application, apply to the resonator
manufacturer for evaluation on the implementation circuit. The oscillation voltage
and oscillation frequency only indicate the oscillator characteristic. Use the
78K0/Kx2 so that the internal operation conditions are within the specifications of
the DC and AC characteristics.
