Figure 5.2 Time delay until Suspend
NOTES:
1. The measurement condition is V
CC = 2.7 V to 5.5 V and Topr = -40°C to 85°C (D, J version) / -40°C to 125°C (K version).
2. Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA26 bit in the VCA2
register to 0.
3. Hold V
det2 > Vdet1.
4. This parameter shows the voltage detection level when the power supply drops. The voltage detection level when the power
supply rises is higher than the voltage detection level when the power supply drops by approximately 0.1 V.
5. Time until the voltage monitor 1 reset is generated after the voltage passes V
det1 when VCC falls. When using the digital filter,
its sampling time is added to t
d(Vdet1-A). When using the voltage monitor 1 reset, maintain this time until VCC = 2.0 V after the
voltage passes V
det1 when the power supply falls.

1. The measurement condition is V
CC = 2.7 V to 5.5 V and Topr = -40°C to 85°C (D, J version) / -40°C to 125°C (K version).
2. Time until the voltage monitor 2 reset/interrupt request is generated since the voltage passes V
det2.
3. Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA27 bit in the VCA2
register to 0.
4. Hold V
det2 > Vdet1.
5. When using the digital filter, its sampling time is added to t

until V

NOTES:
1. Topr = -40°C to 85°C (D, J version) / -40°C to 125°C (K version), unless otherwise specified.
2. This condition (the minimum value of external power V
CC rise gradient) does not apply if Vpor2 ≥ 1.0 V.
3. To use the power-on reset function, enable voltage monitor 1 reset by setting the LVD1ON bit in the OFS register to 0, the
VW1C0 and VW1C6 bits in the VW1C register to 1 respectively, and the VCA26 bit in the VCA2 register to 1.
4. t
w(por1) indicates the duration the external power VCC must be held below the effective voltage (Vpor1) to enable a power on
reset. When turning on the power for the first time, maintain tw(por1) for 30s or more if -20°C ≤ Topr ≤ 125°C, maintain t
w(por1)
for 3,000s or more if -40°C ≤ Topr < -20°C.
