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

    如果在調諧器或電視機附近使用本機或任何其他使用微處理器的電子設備,則可能會產生圖像的噪聲或干擾。如果發生這種情況,請采取以下步驟將本機安裝在盡可能遠離調諧器或T的地方。遠離調諧器或T,遠離本機的電源線和輸入/輸出連接電纜。尤其在使用室內天線或300歐姆饋線。我們建議使用室外天線和75 Q / ohm同軸電纜Noise or disturbance of the picture may be generated if this unit or any other electronic equipment using microprocessors is used near a tuner or TV If this happens, take the following stepsInstall this unit as far away as possible from the tuner or T Run the antenna wires from the tuner or T away from this unit ' s power supply cord and input/output connection cables. Noise or disturbance tends to occur particularly when using indoor antennas or300 ohm feeder wires. We recommend using outdoor antennas and 75 Q/ohm coaxial cables

  • 開關電源濾波電路的優化設計

    隨著科技的發展,人們在日常生活中使用的電器越來越多,電子設備的電磁兼容性(EMC)也越來越重要。所以,人們對電子設備的電磁兼容性的要求也越來越嚴格,越來越規范。而在市場競爭中,如何降低成本、減少設備體積,是各電子設備制造廠家重點研究的課題。通過對開關電源的EMI濾波電路的類別和相應的技術特點進行分析,設計出一種既能提高性能,又能降低成本的濾波電路。With the development of technology, appliances people use in their daily lives, more and more electronic devices electromagnetic compatibility ( EMC ) has become increasingly important. So, people electromagnetic compatibility requirements of electronic devices have become increasingly stringent, more and more standardized. The competition in the market, how to reduce costs, reduce equipment size, is the subject of the electronic equipment manufacturer focused on research. Through the technical characteristics of the respective category and the EMI filter circuit switching power supply is analyzed both designed to improve a performance of the filter circuit can reduce the cost.

  • 步進電機驅動器原理圖+PCB+驅動源碼+使用教程等

    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格,請查閱A3967的參數表。它的最大每相電流從150mA到750mA。可以采用的最大驅動電壓大概是30V,其中包括板載5V的調壓器,所以只需要一個電源。質優價廉,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. The higher the voltage, the higher the torque at high speeds

  • 基于炬芯(Actions) ATS2819的TWS藍牙音箱方案

    ATS2819/ATS2819P標準應用方案主要分為以下功能模塊:Power supply,BlueTooth,Audio Input/Output(包括codec、I2C、SPDIF),FM Receiver,disaplay(LED&LCD),USB,SPI NOR Flash Memory,SD/MMC/MS Card等。1.2原理圖設計總體原則1原理圖設計需要按照方案規格的要求實現各項硬件功能,盡量避免功能模塊相互間的資源沖突。如果存在I/O復用,接收復用等情況,除了需注意檢查I/O上電狀態,接口時序等,還需要注意復用的SIO工作頻率與工作電壓域是否符合要求(如WIO),確保功能設計正確實現。2原理圖設計要求性能達到要求。如穩定性,啟動電壓,功耗,ESD,EMI等。要注意檢查模塊電源開關狀態,選擇的原件標稱及精度、材質,接口保護元件和EMI濾波器等。3系統時鐘26MHZ,要求CL為7~9PF,精度為+-10PPM。這樣才能保證系統能正常工作。4當設計PCB受限于模具大小時,各個模塊無法保證均能得到最優的布局布線(如濾波電容要求靠近IC、走線上要求盡量少的過孔與盡可能短的走線)。因為在此給出一個模塊優先級以供設計人員參考,從而提高方案設計的效率,增加一版work的可行性。將優先級以阿拉伯數據排列
