AC Characteristics
(1) Reset Timing
(VCC = 5.0 V, AVSS = VSS = 0.0 V, TA =
40 °C to +85 °C)
Notes :
tHCYL is the oscillation cycle (1/FCH) to input to the X0 pin.
If the reset pulse applied to the external reset pin (RST) does not meet the specifications, it may cause
malfunctions. Use caution so that the reset pulse less than the specifications will not be fed to the external
reset pin (RST) .
(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 218/FCH, the oscillation stabilization delay time is 26.2 ms. Therefore, the maximum
value of power supply rising time is about 26.2 ms.
Rapid 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.
