4. AC Characteristics
(1) Reset Timing
(VCC = +5.0 V
±10 %, AVSS = VSS = 0.0 V, TA = –40
°C to +85 °C)
Note: tCH is the cycle time of the main clock.
(2) Power-on Reset
(AVSS = VSS = 0.0 V, TA = –40
°C to +85 °C)
Note: Make sure that power supply rises within the selected oscillation stabilization time.
If power supply voltage needs to be varied in the course of operation, a smooth voltage rise is
recommended.

Note that a sudden increase in supply voltage may result in a power-on reset.
When increasing the supply voltage during operation, voltage variation should be within twice the intended increment so that the
voltage rises as smoothly as possible.
