4. AC Characteristics
(1) Reset Timing
(VCC = +5.0 V
±10%, AVSS = VSS = 0.0 V, TA = –40°C to +85°C)
* : tXCYL is the oscillation cycle (1/FC) to input to the X0 pin.
(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.
