Description:
The EPT1060 is a CMOS digital 6-function watch integrated circuit with a 6 digit LCD watch and built-in alarm/chronograph function. The LCD display has a capacity of 6 digits, 7 day mark, AM/PM mark and colon. The watch circuit time base is a 32,768 kHz crystal oscillator. Oscillator RC network components are included on the chip. 25 phase segment outputs and 2 phase backplane outputs are provided for LCD . An on-chip divider is used to generate the LCD drive voltage.
The EPT1060 designed especially for use with 3V Li-battery.
The EPT1060 provides built in transistors to drive EL backlight.
