Notes: 1. The oscillation stabilization time is the period required for the oscillator to stabilize after V
reaches 2.7 V (3.0 V for HD4074618) at power-on or after RESET input goes high after stop
mode is cancelled. At power-on or when stop mode is cancelled, RESET must remain high for
at least t
to ensure the oscillation stabilization time. Since t
depends on the ceramic
oscillator’s circuit constant and stray capacitance, contact the manufacturer when designing a
reset circuit.
2. The oscillation stabilization time is the period required for the oscillator to stabilize after V
reaches 2.7 V (3.0 V for HD4074618) at power-on. The oscillation stabilization time (t
) must be
ensured. If using a crystal oscillator, contact the manufacturer to determine what oscillation
stabilization time is required, since it depends on the circuit constants and stray capacitances.
3. See figure 50.
4. See figure 51. The unit t
cyc
applies when the MCU is in standby mode or active mode.
5. See figure 52.
6. The unit t
subcyc
applies when the MCU is in watch mode or subactive mode.
