General 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. 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.
