option.

200 k to 1444 kHz

1/1 (20 to 2.77 µs) 3 to 6 V

600 k to 4330 kHz

1/3 (20 to 2.77 µs) 3 to 6 V

800 k to 4330 kHz

1/4 (20 to 3.70 µs) 3 to 6 V

Use the no divider circuit option and the

3 to 6 V

recommended circuit constants. If using other circuit

constants is unavoidable, the application must use a

frequency identical to the external clock and observe

the VDD range specification.

External clock used with the ceramic oscillator option

External clock drive is not possible. To use external clock drive, select the 2-pin RC oscillator option.
