Notes:

1 Dynamic consumption current should be measured without load.

2 The parameters are controlled with oscillator crystal with oscillator nominal frequency 32768 Hz

at capacitance values on oscillator input OSCI not more than 6pF, on output OSCO - not more

than 3pF.

3 Nominal value of integrated capacitances on outputs OSCI and OSCO - 12pF and 12pF(crystal
