Highly Integrated IC Provides Complete Motion-Control System

Using a highly integrated, mixed-signal, system-on-a-chip architecture, the M3000 motion-control IC provides a complete system for motion control, handling time-critical motion and motor tasks in silicon to control and position multi-phase step motors. The chip combines major motion and motor control building blocks, while simultaneously working as a high-speed, general-purpose microcontroller, incorporating extensive communication, analog, and system functions for general machine control. A custom hardware block controls the motor itself—current, resonance, and power stage—and handles all of the positioning functions, such as acceleration, deceleration, velocity, positioning, and encoder feedback. The inclusion of extensive communication and general analog functions provides the user the ability to control a large variety of systems without additional circuits. The integration of all major system functions onto one SoC increases reliability and performance while reducing cost and time-to-market. Operating temperature range is -40°C to +85°C, making the M3000 well-suited for commercial and industrial applications. The M3000 comes in various packages with either internal or external flash memory. Contact the company for price and availability information. SYSTEM SEMICONDUCTOR INC., Marlborough, CT.
