AC Characteristics
(1) Reset Timing
(VCC = +5.0 V
±10%, VSS = 0.0 V, TA = –20°C to +85°C)
Note: tXCYL is the oscillation cycle input to the X0.
(2) Power-on Reset
(VSS = 0.0 V, TA = –20
°C to +85°C)
Note: Make sure that power supply rises within the selected oscillation stabilization time selected.
If power supply voltage needs to be varied in the course of operation, a smooth voltage rise is
recommended.
