TMC428-I pb

*leaded version*

Specifications

• Controls up to three 2-phase stepper motors
• Serial 4-wire interface for µC with easy-to-use protocol
• Configurable interface for SPI™ motor drivers
• Different types of SPI™ stepper motor driver chips may by
  mixed within a single daisy chain
  
  
• Communication on demand minimizes traffic to the SPI™ stepper motor drivers chain
• Allows read-out of driver status information
• Programmable SPI™ data rates up to 1 Mbit/s
• Wide range for clock frequency - can use CPU clock up to 16 MHz
• Internal 24 bit wide position counters
• Full step frequencies up to 20 kHz
• Individual micro step resolution of {64, 32, 16, 8, 4, 2, 1} micro steps
• Programmable 6 bit micro step table with up to 64 entries for a quarter sine wave period
• On-the-fly alteration of target motion parameters (like position, velocity, acceleration)
• Read-out facility for current motion parameters (position, velocity, acceleration)
• Power down mode (100 µA) with transparent wake-up for
  normal operation (typ. 10 mA @ 16 MHz)
  
  
• 3.3V or 5V operation with CMOS / TTL compatible IOs (all inputs Schmitt-Trigger)
• Ultra small 16 pin SSOP package (optional 24 pin SOIC package)
• Integrated power-on-reset
