Motion Control System-On-A-Chip

The M3000 motion controller is a highly integrated, mixedsignal system-on-a-chip that combines major building blocks necessary to control and position multiphase stepmotors.

The system also works as a high-speed general-purpose microcontroller with communications, analog, and system functions. A high-speed Risc-based Atmel AVR core runs at 20 MHz and includes a watchdog timer, interrupt controller with two external interrupts, internal and external counter timers, and 20 general-purpose I/O lines. Communications include two SPI ports, a general-purpose Uart, and a Can controller. The system comes with a 64k × 16 program memory, 4k × 8 data ram, and an interface for an external 4k × 8 data block.
