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/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.
For example, when the main clock is operating at 10 MHz (FCH) and the oscillation stabilization time select
option has been set to 214/FCH, the oscillation stabilization delay time is 1.6 ms and accordingly the maximum
value of power supply rising time is about 1.6 ms.
Keep in mind that abrupt changes in power supply voltage may cause a power-on reset. If power supply
voltage needs to be varied in the course of operation, a smooth voltage rise is recommended.
