AC Characteristics
(1) Reset Timing
(VCC = +5.0 V
±10%, AVSS = VSS = 0.0 V, TA = –40°C to +85°C)
Note:
tHCYL is the main clock oscillator period.
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.
If power supply voltage needs to be varied in the course of operation, a smooth voltage rise is
recommended.
