• Do not ground the capacitor to a ground pattern through which a high current
• Do not fetch signals from the oscillator.
For soldering methods and conditions other than those recommended below,
contact an NEC Electronics sales representative.
Do not use different soldering methods together (except for partial heating).
Product quality may suffer if the absolute maximum rating is exceeded even
momentarily for any parameter. That is, the absolute maximum ratings are
rated values at which the product is on the verge of suffering physical
damage, and therefore the product must be used under conditions that ensure
that the absolute maximum ratings are not exceeded.
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
The conversion accuracy may be degraded if the analog input pin is used as
an alternate I/O port or if a port is changed during A/D conversion.
Products with –A or –AX at the end of the part number are lead-free products.
Only the pins of the THD are heated when performing wave soldering.
Make sure that flow solder does not come in contact with the package.
