4. AC Characteristics
(1) Reset Timing
(VSS
= 0.0 V, Ta = 40 °C to +85 °C)
tHCYL : 1 oscillating clock cycle time
Notes:
When the power-on reset option is not on, leave the external reset on until oscillation becomes stable.
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.
Note : For the product that select P62 instead of RST pin by mask option, the only way to initialize the device is by
power on reset. If the power supply rise / cutoff time does not meet the specifications, then power on reset
cannot be generated, and the device become unusable.
