Texas Instruments has developed a family of microcontrollers with TI’s C28x core and control peripherals with an ARM Cortex-M3 core and connectivity in a clearly partitioned architecture that supports real-time control in a single, cost-efficient device. Software libraries for the key applications for the Concerto C2000 MCUs - digital power, motor control and renewable energy - are due in Q3 this year.
To make them easy to use, the devices are supported by an intuitive software infrastructure as well as application and connectivity libraries within controlSUITE software. The series includes multiple safety and security features and is code compatible across the C2000 platform to enable scalability and code reuse in green applications such as intelligent motor control, renewable energy, smart grid, digital power and electric vehicles.
Greener applications require the performance of a real-time control MCU to execute complex algorithms needed for precise, efficient power conversion, which is the essence of efficient motor control, renewable energy and smart grid technologies. But to take that efficiency to new levels that can dramatically save energy, these applications must also be connected for remote data sharing, diagnostics, monitoring and control. The $7 Concerto MCUs enable developers to do both real-time control and connectivity within one microcontroller, eliminating the traditional need to choose between optimal performance and advanced connectivity.
Features and benefits:
- Real-time control subsystem based on TI’s C28x core with floating point and the Viterbi Complex Math Unit delivers 13X performance over existing MCUs as well as industry-leading control peripherals required to design the most reliable, efficient green applications
- Robust host communication subsystem based on Cortex-M3 and connectivity peripherals such as Ethernet, USB On-The-Go, dual CAN, and multiple serial communication ports
- Performance can be tailored to different applications with options for 150/75 MHz, 100/100 MHz or 60/60 MHz on the C28x and Cortex-M3 cores, respectively
- Safety and security features, including up to 1 MB of flash and 132 KB RAM with error correction, parity on CAN and interrupt registers, redundancy for functions, and lock protection
- Free turnkey application and connectivity software libraries, including Ethernet and USB (Digital power, motor control and renewable energy libraries will be available in 3Q11)
- Speeds design with simple development environment that supports programming each subsystem independently
- Roadmap for tailored devices to meet specific smart grid applications, such as smart electric meters and concentrators
Available in a 144 QFP package, Concerto MCUs now start at $6.99 at 1K and samples can be immediately ordered at www.ti.com/concerto-es-lp-pr. The Concerto F28M35x Experimenter Kit is priced at $139. The Concerto F28M35x controlCARD is also available individually for $99. Both are immediately available to order atwww.ti.com/concerto-es-lp. There is an estimated 4 week lead time for samples and kits.
