Welcome to the training module on Piccolo F2806x Microcontrollers.
This training module will introduce Piccolo F2806x microcontrollers and their new features.
Taking a broad look at TI’s embedded processing portfolio, C2000 comes in as a 32-bit microcontroller optimized for real-time control. C2000 offers a broad range of microcontrollers ranging from 40MHz to 300MHz, and from 16KB to 512KB of RAM. Its math-optimized core gives designers the means to improve system efficiency, reliability, and flexibility. Powerful integrated peripherals make C2000 devices the perfect single-chip control solution. With code-compatibility across all C2000 devices, C2000 is the ideal solution for applications such as digital motor control, digital power, lighting, and renewable energy.
C2000 has been designed for real-time control applications since its inception. The portfolio has evolved over the years to merge the performance benefits of its high-performance signal processing core with the integration, low cost and ease-of-use traditionally associated with microcontrollers. And that’s what you see here. C2000 currently has two series: Piccolo, for the most cost-sensitive application spaces, and Delfino, which meets the need of customers that need high-performance floating point. But there is this growing group of developers that need something to fill the gap between the two – developers of real-time control applications that need that tailored 80 MHz mid-range performance, but also require low cost, floating-point ease of use, more connectivity options and more memory. This is especially important for applications like renewable energy, where developers are looking to add the intelligence of networking to wind farms; or hybrid electric vehicles and charging stations. So that’s what we’re here to talk to you about today – more than 15 new low-cost Piccolo MCUs that also bring a brand new math engine and peripheral enhancements, so let’s take a closer look.
So why do engineers need these new MCUs? First, they need to achieve optimal efficiency and functionality. TI enables them to do this with a cutting edge math engine. C2000 is rooted in TI’s 25+ years of digital signal processing leadership, and has always had DSP instructions. C2000 has also since added a revolutionary parallel loop controller (CLA) and now has introduced the VCU, essentially a DSP and system specific Hardware accelerator. Second, engineers need add intelligence while reducing system cost and complexity. The F2806x enables this by adding new communications capabilities within and externally. Most significant are the power line communications optimizations that are part of this device. And third, engineers need to get their own products to market fast. With the software and code generation tools provided for the customers in controlSUITE, and with real-world hardware application development tools, C2000 gives engineers a huge head start by providing software and kits that resemble real-world implementations.
Let’s take a closer look at the device. It starts with leading math capabilities, and F2806x provides up to 3 key features, which are floating point instructions, the control law accelerator (or CLA), and the Viterbi and Complex Math Unit (or VCU) When people think floating-point, they immediately think ease of use benefits, but many aren’t aware of the performance benefits. These graphs show the 40% reduction in cycles that floating-point can bring, which means more bandwidth to do other control functions. For example, a single F2806x device can control two motors, a Power factor correction stage, and facilitate power line communication. The CLA was first introduced with the Piccolo F2803x series and is a coprocessor that acts independently of the CPU. It is optimized for control loops, and also supports floating-point. And the VCU is a brand new extension that includes a viterbi unit, arithmetic unit and CRC unit.
The F2806x devices add floating-point to the C2000™ Piccolo MCU series as well as more memory, more peripherals, and new technologies for real-time control applications. F2806x devices add to the F2803x family with double the memory—up to 256KB of Flash and 100KB of RAM. Performance is boosted to 80 MHz, and additional processing power is gained with the Control Law Accelerator (CLA) as well as the new VCU (Viterbi, Complex Math, CRC Unit) for complex math operations. A larger set of advanced control peripherals includes the new High-Resolution Capture (HRCAP) module. This family is code-compatible with previous C28x-based code, as well as providing a high level of analog integration. An internal voltage regulator allows for single-rail operation. Enhancements have been made to the HRPWM module to allow for dual-edge control (frequency modulation). Analog comparators with internal 10-bit references have been added and can be routed directly to control the PWM outputs. The ADC converts from 0 to 3.3-V fixed full scale range and supports ratio-metric VREFHI/VREFLO references.
Let’s take a moment to look at the VCU. Communications outside the system is becoming more important than ever before. PLC is one method that customers are using to integrate networking and it is a popular method because it leverages existing infrastructure instead of having to install separate, dedicated networks such as Ethernet. However, the power line is a very noisy environment, so you need to do a lot of processing power for filtering, FFT processing, and decoding, to accurately transmit data. In addition to the complexity, developing and evolving protocol standards make it even harder for engineers to create the right solution. Right now, developers have to use a dedicated device to add PLC. This is necessary because of the required processing bandwidth, and it keeps the system relatively modular for future changes in protocols and standards. However, Piccolo with the VCU can eliminate that extra device from the system. The VCU presents a balance of hardware acceleration to increase processing proficiency and flexibility to reprogram for new or updated protocols and standards. This reduces system cost and complexity from both hardware and software standpoints. PLC is just one example of a technology that benefits from the VCU. O ther applications such as automotive radar, and power electronics safety & reliability measurements (such as vibration analysis) benefit from the additional optimized performance.
But for real-time control, you need more than just the brain. So let’s talk about the peripherals. From an input perspective, Piccolo has the best-in-class 3 Mega-samples-per-second ratio-metric 12-bit ADC, ensuring accurate and speedy sensing the input. Three analog comparators allow quick, asynchronous detection and response to conditions like overcurrent or overvoltage. On the output side, the F2806x devices have the industry’s highest resolution PWM with 150 picoseconds of resolution on both frequency and duty cycle. The PWMs are highly flexible in that they can support multiple power topologies. This is critical for renewable energy customers who need to be able to support a specialized DC/DC topology while also controlling an inverter topology, all handled by a single MCU. F2806x enables that. And then, there’s the external communication. F2806x provides all of the industry standard interfaces – Controller Area Network (or CAN), SPI, I-squared-C (I 2 C), UART as well as TI’s Mult that is a flexible serial port that can connect to a wide variety of industry standard codecs and data converters. TI has also added USB 2.0, which is becoming increasingly important for customers that want need to add field firmware upgradeability or data logging. And customers are able to get all of this in the F2806x MCUs, starting at 4.95 in one thousand unit pricing.
And, of course, to get customers started, TI provides a full platform of software, tools and support. C2000 spends a lot of time making sure that customers can easily and fully leverage all of the features of our devices and the breadth of system application knowledge that has been built over the last 15 years. With controlSUITE, all of that knowledge and software is freely available in one location. After downloading controlSUITE at www.ti.com/controlsuite, you’ll have free, full access to a whole slew of device examples, math libraries, and application libraries. All of the hardware files for development tools are also accessible for engineers to freely modify and recreate. You can directly find application notes, technical documents, available training, and even valuable resources from C2000’s developer network. On the hardware tools side, F2806x will have two main, low-cost evaluation kits. First, the F2806x controlSTICK is a full kit in USB stick form factor. With an onboard emulator and access pins, getting started with F2806x is as easy as plugging it in to your computer. A step up is the F2806x Experimenter Kit, which also includes onboard emulation. The Experimenter kit provides access to all F2806x I/O pins and includes a prototyping area. This kit uses the F2806x controlCARD, which can be purchased separately. The controlCARD is completely pin-compatible with other controlCARDs within the C2000 family, allowing it to be plugged into any of our application development kits as well.
