Motorola Expands Embedded Systems Portfolio for Digitally Controlled Motor Systems.Business Editors & High Tech Writers PHOENIX--(BUSINESS WIRE)--May 30, 2000 Sophisticated digital signal processors, microcontrollers and software enable energy efficiency, high levels of integration and cost-effectiveness for motor control Manufacturers of electronic motor systems now have more choices to bring energy efficiency, safety enhancement features and increased reliability to their products. Motorola Inc. (NYSE NYSE See: New York Stock Exchange : MOT) today announced a comprehensive portfolio of embedded controllers and software optimized for motor control systems. These systems are found in many types of home and industrial products, such as refrigerators, automobiles and heating and air conditioning air conditioning, mechanical process for controlling the humidity, temperature, cleanliness, and circulation of air in buildings and rooms. Indoor air is conditioned and regulated to maintain the temperature-humidity ratio that is most comfortable and healthful. systems. Motorola's solutions are designed to meet the increasing demand for energy efficiency, as well as ease of programming and flexibility in designing electronic motor systems. "Motorola has differentiated itself by leveraging the experience gained over decades of working closely with leading automotive, industrial and consumer electronics customers who have used their MCU (1) (MicroController Unit) A computer on a single chip. See microcontroller. (2) (Multipoint Control Unit) A device that is used to moderate a videoconference of three or more end points (users at computers or groups of users devices to build cost-effective electronic motor systems," said Max Baron, Principal Analyst, Logic Markets and Technologies, for Cahners In-Stat Group, a leading semiconductor industry analyst firm. "The newest chips in the DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive 5680X line - based on Motorola's first DSP architecture designed from the ground up to integrate a powerful DSP architecture with MCU capabilities - is a result of that experience. It will meet very well the increasing performance requirements of manufacturers who need the latest in motion control technology." Motorola is uniquely positioned to provide both microcontrollers (MCUs) and digital signal processors (DSPs) in a software-compatible migration path to address customer needs as performance requirements increase. The DSP56800 architecture combines the traditional control functions of an MCU with the performance of a DSP. This is designed to allow electronically controlled motor systems to run advanced algorithms, bringing precision and enhanced energy-efficiency and reliability. In addition to the four new 40-MIP, flash-based high performance DSP controllers, Motorola is expanding its highly integrated 8-bit MCU line for motor control. The 68HC08MR family of 8-bit MCUs is especially well suited for low-cost variable speed, multi-phase motors. In designing the new embedded controllers, Motorola used its vast library of intellectual property - particularly the sophisticated on-chip peripherals that are specific to motor control. "To develop new DSPs for electronic motors, we leveraged the experience gained over decades of working closely with leading automotive, industrial and consumer electronics customers who use our MCU devices for electronic motor systems," said Debbie Drysdale, vice president and general manager of Motorola's Digital Signal Processor Standard Products Division. "Our customers understand that not all applications can be effectively served by one architectural solution, so we offer a range of embedded controllers, along with applications software, advanced motor control algorithms, reference designs and development tools. Motorola's smart DigitalDNA technology is the enabler that allows system designers to significantly reduce cost, improve energy efficiency and add flexibility to virtually all motor control systems." Solutions for Motor-Based Electronic Systems To improve motor technologies - such as Brushless DC (BLDC BLDC Brushless Direct Current (motor) BLDC Boulder Labs Diversity Council ), Permanent Magnet (PM), AC Induction (ACIM ACIM A Course in Miracles (Foundation for Inner Peace) ACIM AC Induction Motor ACIM Association Canadienne de l'Industrie du Médicament (Pharmaceutical Manufacturers Association of Canada) ) and Switched Reluctance (SR) - manufacturers are turning to programmable, digital, embedded controllers. Providing both MCUs and DSPs gives customers maximum flexibility in creating their solutions, ranging from a simple open-loop system to advanced, sensorless closed-loop designs. "What we found with Motorola's microcontrollers is an advanced architecture featuring an extremely well-designed and flexible PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a module," said David Triezenberg, research and development director at Franklin Electric Franklin Electric is a leading manufacturer of submersible pumps, fueling systems and other applications such as submersible electric motors & center pivot irrigation systems. Until 2004, Franklin Electric was primarily a supplier to OEMs such as ITT/Goulds and Pentair. . "The fault input features are ideal for our gasoline pump application because of Underwriter's Laboratory (UL) rules limiting gasoline pressure. Many of the solutions we investigated had a single external fault input, but only Motorola's MCU had four independent fault pins, allowing us to implement both overcurrent protection and the additional UL safety requirements with minimal external hardware." Motorola's 68HC08MR and DSP56800 devices for motor control possess a number of features designed to meet motor-based system requirements To be used efficiently, all computer software needs certain hardware components or other software resources to be present on a computer system. These pre-requisites are known as (computer) system requirements and are often used as a guideline as opposed to an absolute rule. , including: -- Integrated FLASH memory -- Advanced PWM modules optimized for motor control -- Integrated, mixed-signal peripherals, including: -- Analog-to-digital converters (ADC (1) See A/D converter.

In addition, the DSP56800 family features ADC PWM synchronization. All of these features are designed to enable motor control system designers to optimize algorithms quickly, efficiently and reliably, thereby reducing the overall design cycle and time to market. Development Tool Support Motorola, in conjunction with Metrowerks and other independent development tool companies, provides a development environment that includes advanced software generation and debug To correct a problem in hardware or software. Debugging software means locating the errors in the source code (the program logic). Debugging hardware means finding errors in the circuit design (logical circuits) or in the physical interconnections of the circuits. tools, evaluation and development systems cards, and integrated software Separate software components or applications that have been combined into one package.
