AC Characteristics
(1) Reset Timing
(VCC
= 5.0 V, AVSS = VSS = 0.0 V, TA = 40 °C to +85 °C)
* : tHCYL is the period (1/FC) of the oscillation input to X0.
(2) Power-On Reset
(AVSS
= VSS = 0.0 V, TA = 40 °C to +85 °C)
Note : Ensure that the power supply rising time is less than the selected oscillation stabilization delay time.
For example, if the main clock frequency FC
= 10 MHz and 214/FC is selected as the oscillation stabilization
delay time, the resulting oscillation stabilization delay time is 1.6 ms. As rapid changes in the power supply
voltage may cause a power-on reset, if you need to change the power supply voltage while the device is
operating, ensure that the power supply voltage changes smoothly.
