SMC-40 Features
C
SM
The SMC-40 is a microcomputer chip capable of indexing
stepping motors. This advanced controller is fast, low
power and comes in a small package size.
• NO crystal oscillator required
• NO reset circuit required
• Self contained non-volatile memory
• Maximum step rates above 65,000 SPS
• Non-volatile memory for stand alone operation
• Multiple axis control from a single COM port
• Limit and Home inputs
• Go and soft stop inputs
• Six user ports
• Moving/Driver Enable output
• Small 28 pin PLCC28 and TSSOP28 package size
Available single chip (I2 C) peripherals
• Additional NV (EEprom) memory
• Analog input processor
• Encoder feedback processor
