Microchip launches new 10BASE-T1S Ethernet solution to help OEMs easily connect automotive devices

 


【Lansheng Technology News】Automotive designers are leveraging 10BASE-T1S Ethernet solutions to create new partitioning architectures in automotive applications. 10BASE-T1S technology makes it possible to connect low-speed devices to standard Ethernet networks, eliminating the need for dedicated communications systems. Microchip Technology Inc. today announced the launch of a new series of LAN8650/1 MAC-PHY devices that meet automotive application requirements, further expanding its product lineup of automotive-grade Ethernet solutions. The LAN8650 and LAN8651 MAC-PHY include a media access controller (MAC) and serial peripheral interface for connecting devices at the edge of the automotive network.


Microchip's LAN8650/1 device with built-in MAC and SPI enables designers to connect 8-, 16- and 32-bit microcontrollers without a built-in Ethernet MAC to a 10BASE-T1S single-pair Ethernet network. This enables sensors and actuators that connect the digital and real worlds to become part of a full Ethernet architecture. Connecting to even the simplest microcontrollers reduces the overall size and cost of the design.


Matthias Kaestner, vice president of Microchip's automotive business, said: "Microchip will continue to develop automotive connectivity solutions through the 10BASE-T1S product line to provide the industry with turnkey solutions that meet customer requirements. This new technology will bring sensors and execution to the physical world. The controller is always connected to the cloud, enabling a seamless Ethernet architecture in the car, reducing development effort and time to market."


The new family of devices has built-in Time Sensitive Networking (TSN) support, enabling synchronized timing on long-distance Ethernet networks. This time synchronization is critical for many automotive applications such as advanced driver assistance systems (ADAS).


The LAN8650/1 MAC-PHY is automotive qualified and meets AEC-Q100 Level 1 certification standards for enhanced stability in harsh environments, including extended operating temperature range of -40ºC to 125ºC. These devices meet functional safety requirements and are suitable for ISO 26262 applications.


Ethernet solutions maintain strong momentum in the automotive industry due to their comprehensive security protocols to ensure network system security. These systems can be extended to the edge of the network without requiring extensive changes or new development efforts.

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...
