S32K1xx Series Reference Manual 用戶手冊--2029頁 Supports S32K116, S32K118, S32K142, S32K144, S32K146, and S32K148S32K是一款符合AEC-Q100規(guī)范、基于32位ARM Cortex-M4F和Cortex-M0+內核的MCU，適用于通用汽車和高可靠性工業(yè)應用。The S32K1xx product series further extends the highly scalable portfolio of Arm? Cortex?-M0+/M4F MCUs in the automotive industry. It builds on the legacy of the KEA series, while introducing higher memory options alongside a richer peripheral set extending capability into a variety of automotive applications. With a 2.70–5.5 V supply and focus on automotive environment robustness, the S32K product series devices are well suited to a wide range of applications in electrically harsh environments, and are optimized for cost-sensitive applications offering low pin-count options. The S32K product series offers a broad range of memory, peripherals, and package options. It shares common peripherals and pin counts, allowing developers to migrate easily within an MCU family or among the MCU families to take advantage of more memory or feature integration. This scalability allows developers to use the S32K product series as the standard for their end product platforms, maximizing hardware and software reuse and reducing time to market

該步進電機驅動器又稱為EasyDriver，EasyDriver能夠為兩級步進電機提供大約每相750mA（兩極一共1.5A）的驅動。它默認設置為8步細分模式（所以如果你的電機是每圈200步，你使用EasyDriver時默認為每圈1600步），更多細分模式可以通過將MS1或MS2兩個接腳接地進行設置。這是一種基于Allegro A3967驅動芯片的細分斷路器。對于此設計的完整規(guī)格，請查閱A3967的參數(shù)表。它的最大每相電流從150mA到750mA?？梢圆捎玫淖畲篁寗与妷捍蟾攀?0V，其中包括板載5V的調壓器，所以只需要一個電源。質優(yōu)價廉，這玩意兒只要十幾美元，比你自己制作電路板更便宜。步進電機驅動器設計特色：· A3967 Microstepping Driver· MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)· Compatible with 4, 6, and 8 wire stepper motors of any voltage· Adjustable current control from 150mA/phase to 700mA/phase· Power supply range from 6V to 30V.

基于TMS320F28035芯片為控制核心的空間矢量異步電機變頻器 我們設計的異步電機變頻調速器以TMS320F28035芯片為控制核心，通過輸出三相PWM波控制智能功率模塊IPM驅動三相異步電機。我們使用空間矢量SVPWM算法，并對其進行了優(yōu)化。采用檢測反電勢的方法省去了昂貴的光電編碼器，大大節(jié)省了成本。同時開創(chuàng)性的研發(fā)了自動根據(jù)運行環(huán)境調節(jié)的自適應變頻算法，使我們的變頻調速器可以在電網(wǎng)條件惡劣的鄉(xiāng)村山區(qū)工作，由此該變頻器已被一家民用水泵生產企業(yè)預訂。關鍵字 變頻器 TMS320f28035 IPM SVPWM In our design, the asynchronous machine inverter based on the chip of TMS320F28035 drives the three-Phase asynchronous machine by sending three-phase PWM waves to the IPM, which is short for the Intelligent-Power-Module. The SVPWM (space vector pulse width modulation) strategy is applied to our control algorithm and we optimize it mainly in two aspects. Firstly the inverter detects the speed by measuring the Back EMF instead of installing an expensive photoelectric encoder for costs reduction.
This manual documents the Microcontroller profile of version 7 of the ARM? Architecture, the ARMv7-M architecture profile. For short definitions of all the ARMv7 profiles see About the ARMv7 architecture, and architecture profiles on page A1-20.ARMv7 is documented as a set of architecture profiles. The profiles are defined as follows: ARMv7-A The application profile for systems supporting the ARM and Thumb instruction sets, and requiring virtual address support in the memory management model. ARMv7-R The realtime profile for systems supporting the ARM and Thumb instruction sets, and requiring physical address only support in the memory management model ARMv7-M The microcontroller profile for systems supporting only the Thumb instruction set, and where overall size and deterministic operation for an implementation are more important than absolute performance. While profiles were formally introduced with the ARMv7 development, the A-profile and R-profile have implicitly existed in earlier versions, associated with the Virtual Memory System Architecture (VMSA) and Protected Memory System Architecture (PMSA) respectively.

Spartane-6 LXand LXT FPGAs are available in various speed grades, with -3 having the highest performance. The DC and AC electrical parameters of the Automotive XA Spartan-6 FPGAs and Defense-grade Spartan-6Q FPGAs devices are equivalent to the commercial specifications except where noted. The timing characteristics of the commercial(XC)-2 speed grade industrial device are the same as for a-2 speed grade commercial device. The -2Q and -3Q speed grades are exclusively for the expanded(Q) temperature range. The timing characteristics are equivalent to those shown for the-2 and-3speed grades for the Automotive and Defense-grade devices.Spartan-6 FPGA DC and AC characteristics are specified for commercial (C), industrial (), and expanded (Q) temperature ranges. Only selected speed grades and/or devices might be available in the industrial or expanded temperature ranges for Automotive and Defense-grade devices.
