Notes on Internal DC-DC Regulator
Since this product contains a regulator, be sure to supply current at 3.3 V to the VCC pin and insert a bypass
capacitor of about 0.1
F to the C pin for the regulator.
The A/D converter requires a 3.3-V power supply separately.
Notes on using the STOP mode
The regulator built in this product stops in the STOP mode. If the regulator stops due to a malfunction caused
by noise or a fault in the power supply during normal operation, the internal 2.5-V power supply may go below
the lower limit of the guaranteed operating voltage range. When using the STOP mode with the internal regulator,
therefore, be sure to supply an auxiliary external power to prevent the 3.3-V power supply from coming down.
Even in that case, the internal regulator can be restarted by input of a reset signal (To restart the regulator, keep
the reset pin at the L level for at least the oscillation settling time).
Using an external clock (for normal use)
X0
X1
Note : To use the STOP mode (oscillation stop mode), insert a resistor to the X1 pin.
