Notes:
1. V_det0 indicates the voltage detection level of the voltage detection 0 circuit. Refer to 7. “Voltage Detector” for
details.
2. When using power-on reset, hold the external power V_CC1 at or below V_por1 during t_w(por), and then turn it on.
t_w(por) is 30 s or more when -20°C ≤ T_opr ≤ 85°C, and 3000 s or more when -40°C ≤ T_opr < -20°C.

The measurement condition is V_CC1 = 1.8 to 5.5 V and T_opr = 25°C, unless otherwise specified.
