EM1344 Overview
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 bination, to the two oscillator terminals, with a maximum total capacitance of 48pF. Both the motor pulse period and the motor pulse width are maskprogrammable (see page 6 for available options).
