(1) LVD detection voltage of interrupt mode or reset mode
(T
A = -40 to +150C, VPDR  EVDD0 = EVDD1 = VDD  5.5 V, VSS = EVSS0 = EVSS1 = 0 V)
Parameter Symbol Conditions MIN. TYP. MAX. Unit

Supply voltage level VLVD0 Power supply rise time 4.62 4.74 5.22 V
Power supply fall time 4.52 4.64 5.11 V
VLVD1 Power supply rise time 4.50 4.62 5.09 V
Power supply fall time 4.40 4.52 4.98 V
VLVD2 Power supply rise time 4.30 4.42 4.87 V
Power supply fall time 4.21 4.32 4.76 V
VLVD3 Power supply rise time 3.13 3.22 3.55 V
Power supply fall time 3.07 3.15 3.47 V
VLVD4 Power supply rise time 2.95 3.02 3.33 V
Power supply fall time 2.89 2.96 3.23 V
VLVD5 Power supply rise time 2.74 2.81 3.11 V
Power supply fall time 2.68
Note
2.75 3.00 V
Minimum pulse width tLW 300 µs
Detection delay time tLD 300 µs
Note The minimum value exceeds below the lower limit operation voltage (2.7 V), however, in reset mode, normal
operation (same behavior when VDD = 2.7 V) is possible until a reset is effected at the power supply falling time.
(2) LVD detection voltage of interrupt and reset mode
(T
A = -40 to +150C, VPDR  EVDD0 = EVDD1 = VDD  5.5 V, VSS = EVSS0 = EVSS1 = 0 V)
