How long can automotive MCU chips be "short"?

 


The chips used in automotive electronics are mainly four categories: main control chip, power chip, image sensor chip and storage chip. As the core chip of motion control, MCU has a wide range of applications in automotive electronics and is indispensable for automotive electronics.


As the key chip for the development of automobiles from electrification to intelligence, MCU has more and more application fields, such as window controllers, on-board diagnostic systems, radar applications, automotive lighting applications, automotive central control, vehicle power and safety, etc. , On average, about 100 MCUs are used in a car.


In the process of the evolution of automobiles to intelligent systems, not only higher and higher requirements are put forward for the safety, stability, and consistency of MCUs, but also MCUs are required to have higher computing power, stronger network interfaces, and lower power consumption. As a result, car-grade MCUs need longer testing and experimentation time and higher investment before they can be put on the car and go into mass production.


The global automotive MCU market has long been monopolized by leading companies. Renesas, NXP, Microchip Technology, Infineon, STMicroelectronics, and Texas Instruments have a market share of more than 90%, and all of them are IDM models. Therefore, the expansion of production by the six major manufacturers has become a key factor in solving the core shortage problem of automotive-grade MCUs.


The shortage of MCU is due to the insufficient production capacity of 8-inch lines at the supply level, and the surge in the use of automotive MCUs on the demand side. At present, the shortage of cores in automotive-grade MCUs has improved, from a comprehensive shortage in the past two years to a structural shortage.

What are the Benefits of Power Optimizers?

Image
  Power optimizer for solar panels is a DC/DC converter that is connected to each solar panel in the PV system, turning them into smart modules. By constantly monitoring the maximum production capacity of each individual solar module, optimizers can increase your PV plant energy production – potentially increasing revenue and shortening system payback time. Simply put, the main benefit of power optimizer is that it maximizes the performance of each panel individually. What are the benefits of power optimizers and why are they needed? When installing solar panels, the panels are connected into groups or arrays. In the case of roof-mounted and in-roof panels, there are usually 12-20 solar panels in one group. If the productivity of one of these panels decreases (shadows from trees and clouds, dust, bird droppings, failures of PV components and other factors), then the productivity of the whole group decreases. Defective or shaded panels may produce 15 to 25 percent less solar energy ...

What is a Power Conditioner?

Image
  Looking to protect your sensitive and expensive electronics? Surge protection is a great start, but power conditioners also offer valuable protection for components in entertainment and sound systems, as well as home office devices. What does a power conditioner do that a surge protector can’t? Surge protectors are a great defense against damaging voltage spikes. However more than surges and spikes can effect certain sensitive electronic devices. Radio frequency interference (RFI), electro-magnetic interference (EMI) and voltage fluctuations can also effect sound, entertainment, and office devices, causing a reduction in sound and picture quality. How does it work? Power conditioners act as a buffer between the outlet and your system, smoothing out voltage fluctuations as well as radio and electromagnetic interference that can effect system performance. Initially used in industrial, research and laboratory applications, not long after the introduction of home computer systems, th...
