Five stellaris microcontrollers based on ARM cortex M3 are available from Cutter electronics . The Cortex-M3 offers increased functionality for complex motors and motion control, complete with development kits.
Luminary Micro is represented by cutter electronics a fabless semiconductor company that designs, markets, and sells award-winning ARM cortex M3 processor-based microcontrollers to embedded developers.
The MCUs and development kits are available in luminary micro’s global sales channel immediately and offer powerful features designed for motion control applications, with several application examples being displayed at luminary micro’s booth, #10-520, at Embedded World in Nuremberg, Germany, February 13-15, 2007.
Luminary Micro will also offer a select preview of upcoming products to industry media at the show. The Stellaris line of MCUs, which won four awards in 2006, brings high-performance 32-bit computing to cost-sensitive embedded microcontroller applications at a cost equivalent to or better than legacy 8- and 16-bit devices.
All of the Stellaris MCUs are targeted at embedded and industrial applications, such as:
Building and home automation;
Motion control; and
Industrial power control devices.
The microcontrollers and other parts offer increased functionality for sophisticated motion-oriented applications such as those found in;
Industrial conveyer systems,
CNC and other milling machines
The associated feature-rich development kits include evaluation tool suites, demonstration RTOSes, example programs, and everything a developer needs to get up and running in 10 minutes or less, for total experience.
The high-resolution glitchless PWM waveform generators offer meticulous performance even with the exacting demands of high-performance motion control.
Stellaris has embedded developers up and running quickly. Luminary micro has 24 Stellaris MCUs available in global distribution, less than one year after Luminary micro was selected as ARM’s lead partner for Cortex-M3 development.
Luminary micro has customer design wins across the Stellaris family, including the new devices.
With the extensive ARM ecosystem of tools, software, and support, embedded designers can enter the ARM family with Stellaris microcontrollers and conceivably never have to upgrade architectures or change tools again.
Five New Stellaris MCUs are perfect for motion control. Stellaris family MCUs are based on the ARM Cortex-M3 processor, the microcontroller member of the ARM Cortex processor family.
Designed for serious microcontroller applications, Stellaris family provides entry into the industry’s strongest ecosystem, with code compatibility.
The additional advantages include:
Easy and cost-effective to upgrade from 8- and 16-bit applications, requiring less flash code space and delivering a 10x improvement in performance over 8051 cores and an 8x improvement in performance over PIC24F cores.
Extends ARM7 family processor capabilities in critical MCU applications with a 4x improvement in control processing performance, real-time interrupt response capability and predictable deterministic, interrupt behaviour while requiring just half the flash code space of ARM7 control applications.
The Cortex processor has more than 50 MIPS with a demonstrable 20x performance roadmap.
The five new Stellaris family members have been optimised to support the complex algorithms necessary for efficient energy-saving motion control applications.
The LM3S618 and LM3S818 are particularly well-suited for controlling a wide range of variable speed three-phase and single-phase AC induction motor control using space-vector or sine-wave modulation.
The LM3S317, LM3S617, and LM3S817 are optimised to control a wide range of stepper motors. The stepper motor system designers have had to choose between a basic unipolar control method giving up both high torque and high step rate capability or a dedicated control chip that lacks extensible intelligence.
Using the LM3S317/LM3S617/LM3S817 devices for stepper motor system control provides the system designer with the headroom for high-performance chopper control in order to operate a stepper motor at both high torque and high step rates.
