• Micro-step driven stepping motor driver×2
• PWM driven forward/reverse motor driver
(changeover to the micro-step driving stepping motor driver 1ch possible) × 2
• PWM driven forward/reverse motor driver×2
• Constant-current forward/reverse motor driver × 1
• Two-phase, single-two phase full torque, single-two phase, 4W1-2, phase excitation drive changeover possible
(1/2/3/4ch)
• Progress of micro-step driven excitation steps by clock signal input only (1/2/3/4ch)
• Holding electrification current changeover in four steps possible by serial data (1/2/3/4ch)

Status setting data latched
Input DATA and SCLK after setting of STB = “L”. SCLK is not accepted in the state with STB = “H”.
Input DATA from D0 to D7 in this order. CLK performs data transmission at the rise edge and latches all data at rise
of STB after transmission of all data.
All of serial data is reset to “0” with ST = “L”. and at the voltage to cut VCC low voltage.
Timing to Reflect Serial Data to the Output
• PWM mode (Applicable to 3, 4, 5, and 6ch)
Type 1: FR and DECAY settings during PWM drive are reflected simultaneously with the STB signal of data
latching.
• STP mode (Applicable to 1, 2, 3, and 4ch)
Type 1: HOLD, RESET, CUT ENABLE settings and reference voltage setting are reflected simultaneously with the
STB signal of data latching.
Type 2: Forward/reverse (F/R) and excitation mode (MS) settings made during STEP setting are reflected at rise of the
next clock of data latching.
