Notes: 1. Applies to HD404052, HD404054, HD4074054, HD404092, HD404094, HD4074094.

2. Applies to HD40A4052, HD40A4054.

3. SEL = 1

4. SEL = 0

5. The oscillation stabilization time is the period required for the oscillator to stabilize after V

reaches 2.7 (HD4074054, HD4074094)/1.8 (HD404052, HD404054, HD404092, HD404094) /4.0

(HD40A4052, HD40A4054)V at power-on, or after

RESET input goes low or STOPC input goes

low when stop mode is cancelled. At power-on or when stop mode is cancelled,

RESET or

STOPC must be input for at least t

RC to ensure the oscillation stabilization time.

If using a

ceramic oscillator, contact its manufacturer to determine what stabilization time is required, since

it will depend on the circuit constants and stray capacitance.

6. Applies to ceramic oscillator only.

7. Refer to figure 68.

8. Refer to figure 69.

9. Refer to figure 70.

10. Refer to figure 71.

11. Analog comparator stabilization time is the period for the analog comparator to stabilize and for

correct data to be read after entering RD

0/COMP0, RD1/COMP1 into analog input mode.
