PHOENIX -- Motorola's Semiconductor Products Sector here today announced a line of embedded controllers and software optimized for motor control systems. These solutions are intended to meet the increasing demand for energy efficiency, as well as ease of programming and flexibility in designing electronic motor systems.
Motorola is offering both its microcontrollers and digital signal processors in a software-compatible migration path. The DSP56800 architecture combines the control functions of an MCU with the performance of a DSP. This allows electronically controlled motor systems to run advanced algorithms, increasing the precision, energy-efficiency and reliability of these systems. . In designing the new embedded controllers, Motorola called on its large library of sophisticated on-chip peripherals and other intellectual property.
In addition to four new 40-mips, 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 targeted at low-cost variable speed, multi-phase motors
"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.
Because not all applications can be effectively served by one architectural solution, Motorola offers range of embedded controllers, along with applications software, advanced motor control algorithms, reference designs and development tools, she said. "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."
Motorola's 68HC08MR and DSP56800 devices for motor control possess a number of features designed to meet motor-based system requirements, including integrated flash memory and advanced pulse-width-modulation (PWM) modules optimized for motor control.
Among the integrated, mixed-signal peripherals analog-to-digital converters (ADC), onboard voltage regulation, a Controller Area Network (CAN) 2.0 A/B module, asynchronous serial communications interfaces, and a high-speed synchronous serial interface/
Both the 68HC08MR and DSP56800 families feature PWM waveform distortion correction, as well as multiple fault inputs and stop clock detection. 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.
Motorola provides a development environment that includes advanced software generation and debug tools, evaluation and development systems cards, and integrated software modules. Motorola has called on independent software developers as well as its own Metrowerks subsidiary, which it acquired last year. The offering includes a software development kit and an application program interface (API) that enables portability of applications software between MCUs and DSPs, preserving customers' investments in legacy code.
"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 devices to build cost-effective electronic motor systems," said Max Baron, principal analyst for logic markets and technologies at Cahners In-Stat Group. "The newest chips in the DSP5680X 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."
Samples of both the DSP56F803 and DSP56F805, along with software and development tools, are expected to be available through authorized distributors in June. Samples of the DSP56F801 and DSP56F807 are scheduled for September, with list priced starting at less than $5.00 in quantities greater than 100,000.
Samples and production units of the 68HC908MR32 are expected to be available in September. Suggested list prices range from$6.05 for the 68HC908MR32 in 10,000-piece quantities, to under $5.35 in quantities greater than 100,000. Other members of the 68HC08MR family are expected to be available later in the year.
