PRELIMINARY
S6J3350 Series
*A Relevant pins: All general-purpose ports and analog input pins
• Corresponding pins : all general-purpose ports
• Use within recommended operating conditions.
• Use at DC voltage (current).
• The +B signal should always be applied by connecting a limiting resistor between the +B signal and the microcontroller.
• The value of the limiting resistor should be set so that the current input to the microcontroller pin does not exceed rated values
at any time regardless of instantaneously or constantly when the +B signal is input.
• Note that when the microcontroller drive current is low, such as in the low power consumption modes, the + B input potential
can increase the potential at the VCC pin via a protective diode, possibly affecting other devices.
• Note that if the + B signal is input when the microcontroller is off (not fixed at 0 V), since the power is supplied through the pin,
the microcontroller may operate incompletely.
• Note that if the +B signal is input at power-on, since the power is supplied through the pin, the power-on reset may not function
in the power supply voltage.
• Do not leave + B input pins open.
Example of a recommended circuit
S6J3350 series
Note:
− Application of stress (e.g., voltage, current, temperature) exceeding the absolute maximum rating may cause damage to the
semiconductor device. Therefore, make sure that nothing exceeds the rating.
