H1344, CMOS Circuit for Analog Quartz Clocks

The H1344 is a low power 32kHz analog clock integrated circuit designed in CMOS technology to drive a bipolar stepping motor.

A set of capacitors is provided on chip to be connected, in any combination, to the two oscillator terminals, with a maximum total capacitance of 48pF.

Both the motor pulse p
