Real time controller obtains new join function
[introduction] in current industry domain, apply to what automation of all sorts of electric machinery drive, factory and high power electrified wire netting apply to have a variety of solutions and framework. Among them a lot of have reliable function and link, but however the price is high, because they may have complex design and high cost, and need many chip toward contact to satisfy systematic requirement. In the market of constant change, it is admittedly important that the design differs dissimilation, but efficiency and performance grow to the lifecycle of the product and enterprise can last for a long time finally more crucial however.
You may ask oneself, how am I “ the get victory in competition? ” or “ what is to help me keep the ideal option of business and implementation future development? The core of ” problem is in become a function at collect, control in real time among them can join when solid reality.
Brand-new the F2838x of C2000™ real time controller of series is offerred more optimized join option, control function gets rising, and can apply in industry and a systematic level flexibility is shown in application of high power electrified wire netting. If the graph is shown 1 times, this series is a F2837x parts of an apparatus that has function to enhance a function and a new join management implement, and one can uninstall processing concentrated model correspond and optimize connective, be based on Arm®The subsystem of Cortex®-M4.

F2838x is passed enable normally by FPGA/ complex but small controller of parts of an apparatus of process designing logic, special integrated circuit and communication (MCU) / the function that microprocessor executes, can be automation of connective servo driver, communication driver, factory and equipment of industrial power source to offer the solution of approximately odd chip.
Through be based on Arm®The special join of Cortex-M4 manages implement implementation corresponds in real time. As a result of compositive EtherCAT function, need not use exterior ASIC. Still support 10/100 aether net, CAN FD, USB and all sorts of high speed are serial port. In addition, fast and serial interface (FSI) can realize the communication that is as high as 200 Mbps, realize low cost way on segregation bar.
Typical FPGA/CPLD function comes true by many F2838x function. Can configure logic piece (CLB) allow:
– found interface of absolute value coder
– special pulse alignment is logistic
– the client changes custom-built timer, serial interface and inverter protection mechanism
Road of annulus of fast electric current (FCL) the technology can be in the magnetic field of driver of servo of key of time inline processing that is less than 500ns is directional operating ring road. Still include to be able to connect PWM of more advanced and the Sigma-Delta filter module that receives converter of general segregation Delta-Sigma, other high resolution (most 32 EPWM passageway) , and the advanced comparator subsystem that is used at inverter protection and agile timer synchronism.
Through implementation of the following means high-powered loop controls:
– use trigonometry maths unit (TMU) the C28x that increased to precede™DSP kernel, in order to quicken crucial Arctan, Sin and Cos function;
– use hardware of new-style and fast integral division, use at efficient computation;
Use 64 floating-point unit, use at raising precision of servo motion pilot.
Control law accelerator (CLA) can use at increasing collateral control or signal processing. 4 independence that have aftertreatment hardware converter of 16 accurate modulus has the new-style sheet that makes usable passageway double to carry mode. Uninstall lead plane and communication task join management implement can release a loop, with special control at real time.
Once throw overall production, f2838x series will offer 6 kinds of configuration (watch 1) . The mark of all parts of an apparatus deserves to all include join management implement with aether net. Optional configuration includes sheet (1.0 MB shines put) or double (1.5 MB shines put) C28x adds control law accelerator (CLA) subsystem, can configure logic piece visit and EtherCAT function. F2838x uses array of bar of ball of fine span of ball of solder of 16 Mm×16 Mm 337 to enclose, knot Wen Wei – 40°C comes 125°C.

Well-known, the 3 gist element that control, flexibility and function are automation of electric machinery drive, factory and application of high-power electrified wire netting. Want to will join only compositive go up in a chip, you had control of a real time and connective MCU, the business that can conduct you grows ahead, realizing systematic level flexibility in the near future.
