E1217X

Watch IC, 32kHz standard watch CMOS IC

**Description**

The e1217X is an integrated circuit in CMOS silicon gate technology for analog watches. It consists of a 32-kHz oscillator, frequency dividers down to 1/64 Hz, output pulse formers and push-pull motor drivers. Integrated capacitors are provided select able mask option for tuning of the crystal. Low current consumption and high oscillator stability are enabled by an on-chip voltage regulator.
