4 / 23 page

Allowable Operating Ranges at Ta = –20 to +70°C, VSS = 0 V

Note: * Crystal oscillator recommended CI value

≤ 35 kΩ (for a 75 kHz crystal)

The circuit constants for the crystal oscillator circuit depend on the crystal used, the printed circuit board pattern, and other items. Therefore we

recommend consulting with the manufacturer of the crystal for evaluation and reliability.

The extremely high input impedance of the XIN pins means that applications must take the possibility of leakage into account.
