According to investigations and research by relevant institutions, the future of the automotive electronics industry is green, environmentally friendly, secure and connected. The Internet of Vehicles is an important development trend. In fact, the Internet of Vehicles is a new network that combines the Internet with the Internet of Things-based Internet of Things. The smart car in the era of car networking has two characteristics: First, the car and the car can maintain a relatively fixed distance, can achieve zero collision; Second, the team between the car and the car is randomly carried out, according to The destination of the owner, through GPS positioning and automatic communication between vehicles, can temporarily team or leave the team between the car and the car to improve traffic efficiency.
NXP: LPC54100 security chip is a traditional advantage
At present, the application range of NXP MCU products has covered industrial control, smart meters, consumer electronics, automotive electronics aftermarket, medical equipment and other fields. The rhythm of the new products is also very frequent. The LPC54100 series can be said to be a breakthrough product of the NXP microcontroller product line in recent years. These are the foundations that drive the continued growth of NXP's MCU business. NXP will introduce more new products based on the LPC54100 platform extension, and will also focus on lower power, higher performance and more secure MCUs.
The LPC54100 is the lowest power, or most energy-efficient family of microcontrollers from NXP. It combines processing power and power. Based on the Cortex-M4 and Cortex-M0+ dual-core architecture, the Cortex-M4 is available. For big data operations, Cortex-M0+ can be used for data acquisition and external interface communication; up to 100MHz running speed with floating-point arithmetic coprocessor for fast data processing; while having sleep, deep sleep, power down, deep A variety of different low power modes such as electricity. In applications such as the mobile phone SensorHub, the LPC54100 provides a minimum of 3μA sensor monitoring mode; the Cortex-M0+ in dual core can be monitored, data acquisition management, and communication at 5 5μA/MHz. The Cortex-M4 can be used at 100μA/ Sensor algorithm operations are performed under MHz conditions.
Wireless integration, security, and integration of wireless technologies are one of the important manifestations of MCUs to provide solutions for different applications. Integrate between related products and launch new products in due course. In terms of Wi-Fi, NXP has also developed in cooperation with the industry's leading Wi-Fi RF suppliers to launch MCU+Wi-Fi-based modules for use in IoT smart homes, smart lighting, and intelligent industrial control. As an area of ​​strength for NXP, the combination of security and MCU is equally worthy of attention.
Freescale: Car MCU three swords
In the automotive electronics arena, Freescale continues to innovate and introduce the Kinetis family of microcontrollers based on the ARM Cortex architecture. Li Xing, Product Manager, Freescale Automotive Electronics Microcontroller Asia Pacific, said the Kinetis EA series of microcontrollers combines the fine traditions of Freescale's automotive microcontrollers with a revolutionary new development environment to help automotive electronic components. Suppliers can achieve initial prototyping within 24 hours, typically reducing development cycles by two weeks or longer and simplifying the overall development process for automotive electronics applications.
In the Chinese market, the speed of listing is critical, and developers are very familiar with the ARM architecture. Based on the Kinetis EA family of MCUs, it offers a rich automotive electronics reference design and a range of easy-to-use tools that enable automotive application engineers to quickly prototype. 24-hour prototyping is available through the product development portal, which guides users through common development processes and includes a variety of integrated software and hardware development kits to help reduce development time and development costs. Freescale's automotive electronics MCUs also feature 32-bit Qorivva and 8-16-bit S08/S12/MagniV mixed-signal MCUs based on the Power architecture.
Target applications for the Kinetis EA family of microcontrollers include seats, sunroofs and oil/pump systems; versatile body electronics such as body controls, parking assist, CAN / LIN nodes, interior lighting and engines for motorcycle powertrains Control System. In terms of development resources, Freescale's support tools for participating in the supply include reference designs (including motor control, body network, LED lighting and motorcycle engine control); software packages for body, lighting, motor control, etc.; driver packages And a low-cost StarterTRAK board. "Freescale's unparalleled automotive portfolio, superior eco-system support, rigorous automotive certification, and pin-to-pin scalability make the Kinetis EA family uniquely positioned to drive ARM-based MCUs into the global automotive market. The mainstream components." Li Xing stressed.
Will Tu, Director of ARM Embedded Applications Marketing, also said: "Freescale is committed to serving and driving the automotive market in China and around the world. The ARM architecture helps meet the low energy and high performance needs of the automotive market. In addition, ARM Ecology The system helps developers access third-party IP and resources to speed time-to-market. We are excited to work with Freescale to help extend our architecture to new automotive electronics."
Renesas Electronics: Automotive Electronics offers the best MCUs and solutions
Renesas has a market share of more than 20% in the world's automotive MCUs. It is used by major automotive electronics manufacturers such as Bosch, Continental, Delphi, TRW, Aisin and Denso. The products of these automotive electronics manufacturers are used by many car manufacturers around the world. For cars, quality and performance are of the utmost importance. Automakers and automotive electronics manufacturers have highly valued the high quality and high performance of Renesas' automotive MCUs.
The "smart" of the car is the basic performance of the MCU and MPU. The power consumption of the MPU of the PC and the server increases and reaches the limit as the CPU speeds up. Although the vector developed for the multi-core is changed, this is the same for the high-end MCU and the MPU for the automobile. Automotive MCUs are used in harsh environments and require high temperatures. For example, the engine ECU was originally placed in the cabin and is now installed in the engine compartment to operate at a temperature of 125 °C. Renesas uses the SH-2A and SH-4A multi-core methods to develop new products for controllers and processors. Renesas has added the Lock-Step Dual feature to the SH-2A of the MCU for brake and steering control. It compares the working conditions of two CPUs frequently, and also monitors the working status of the DMA controller and the peripheral bus bridge in duplex.
