4. AC Characteristics
(1) Reset Timing
(AVCC = VCC = 5.0 V, AVSS = VSS = 0.0 V, TA = –40
°C to +85°C)
Note: TXCYL is the oscillation cycle (1/FCH) 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.
