AC Characteristics
(1) Reset Timing
(VSS
= 0.0 V, Ta = 40 °C to +85 °C)
* : tHCYL 1 oscillating clock cycle time
Note: 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
(VSS
= 0.0 V, Ta = 40 °C to +85 °C)
Note: : The supply voltage must be set to the minimum value required for operation within the prescribed default
oscillation settling time.
