The e1217D 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. For tuning of the crystal, integrated capacitors are provided (selectable mask option). Low current consumption and high oscillator stability are enabled by an on-chip voltage regulator.
