Notes: 1. When the subsystem oscillator (32.768 kHz crystal oscillation) is used, use within the range

0.4 MHz

≤f

OSC≤1.0 MHz or 1.6 MHz≤fOSC≤8.5 MHz. The SSR1 bit of the system clock select

2. The typ. value is the value when V

CC = 3.5 V.

3. Applies to HD40A4372/4, HD40A4382/4, HD40A4388/9, HD40A4081/2, HD40A4084,

HD407A4374, HD407A4384 and HD407A4389 when V

CC = 4.0 to 5.5 V.

4. Applies to HD404374 Series.

5. Applies to HD40C4372/4, HD407C4374, HD40C4382/4, HD407C4384, HD40C4388/9,

HD407C4389, HD40C4081/2, HCD40C4082, HD40C4084, HCD40C4084.

6. The oscillation settling time is defined as follows:

(1)

The time required for the oscillation to settle after V

CC has reached standard minimum at

power-on.

(2)

The time required for the oscillation to settle after

RESET input has gone low when stop

mode is cleared.

To ensure enough time for the oscillation to settle at power-on hold the

RESET input low for at

least time t

RC.

The oscillation settling time will depend on the circuit constants and stray

capacitance. The resonator should be determined in consultation with the resonator

manufacturer. With regard to the system clock (OSC

1, OSC2), bits MIS1 and MIS0 in the

miscellaneous register (MIS) should be set according to the oscillation settling time of the

resonator used.

10. Applies to Mask ROM.

11. Applies to ZTAT

TM.

13. Applies to HD40C4372/4, HD407C4374, HD40C4382/4, HD407C4384, HD40C4388/9,

HD407C4389.
