PURPOSE:To obtain a useful voicing timepiece in applying in the timepiece with small-sized and low electric power consumption such as a watch or the like, by making original oscillations of LSI for a timepiece and LSI for a voice synthesizing same and operating both LSIs at low voltage. CONSTITUTION:The oscillations of LSI for a timepiece and LSI for voice synthesizing are made same and the both LSI are arranged to be operated with low voltage for LSI of the timepiece. For example, a voice watch system is constituted of a 3V battery power source B, LSI.W-LSI for the timepiece, LSI. VPC for a voice synthesizing, a liquid crystal display device LCD and a transistor amplifier Amp, etc. The battery power source B is used in common with W- LSI and VPC, and 3V voltage is applied to the both LSIs. A crystal resonator X of 32.768kHz is connected between OSCin at the W-LSI side and a terminal OSCout and is oscillated, and is arranged to supply the oscillating signal to a terminal EXTOin of VPC. |
