The EDE1200 Unipolar Stepper Motor IC is a 5 volt, 18 pin package designed to interface a logic-
level input byte to a stepper motor. The EDE1200 is capable of self-clocking in the free-standing
'RUN' mode, as well as external clocking in the 'STEP' mode. In addition, half-stepping and
directional control are also available. The TTL-level outputs sequence the stepper drive circuits that
consist of standard power transistors or a transistor array IC. The EDE1200 features the ability to
change the stepping rate while the motor is stepping and to take an unlimited number of steps in
continuous 'RUN' mode. Inputs are TTL/ CMOS compatible.
RUN mode
In the 'RUN' mode, activated by a low on pin 10, the EDE1200 will cause the motor to rotate
according to the following parameters:
Direction (pin 7): 1 = clockwise, 0 = counter-clockwise
(If a clockwise command causes counterclockwise rotation of motor, reverse the
sequence of the motor’s four phase wires.)
Half-Stepping (pin 8): 1 = normal stepping, 0 = half stepping (doubles step resolution)
Speed Control [C,B,A] (pins 13,12,11): these three active-low bits select one of eight
rotational speeds. Refer to Tables One & Two below for speed range details.
