4. AC Characteristics
(1) Reset Timing
(VCC = 5.0 V
±10%, VSS = 0.0 V, TA = –40°C to +85°C)
* : tXCYL is the oscillation cycle (1/FC) to input to the XO pin.
(2) Specifications for Power-on Reset
(VCC = 5.0 V
±10%, VSS = 0.0 V, TA = –40°C to +85°C)
Note: If power-on reset provided is selected, an abrupt change in the power supply voltage could cause a power-
on reset. When changing the power supply voltage during operation, voltage fluctuations should be two or
less times for smooth start-up.
