NXP takes the lead in launching 28 nm RFCMOS radar single-chip series to help software-defined cars build ADAS architecture

 


【Lansheng Technology News】On January 10, 2024, NXP Semiconductors today released a new series of automotive radar single-chip products. The new SAF86xx single chip integrates a high-performance radar transceiver, multi-core radar processor and MACsec hardware engine to enable advanced secure data communication over automotive Ethernet. Paired with NXP's S32 high-performance processor, in-vehicle network connectivity and power management, this complete system solution paves the way for advanced software-defined radar.


The highly integrated radar SoC (system on a chip) is expected to be able to stream large amounts of low-level radar sensor data at 1Gbit/s (maximum) speed, helping automakers optimize the next-generation ADAS partition of software-defined cars while supporting the transition to new architectures a smooth transition. In addition, OEMs can easily add new software-defined radar capabilities through over-the-air updates (OTA) during the life of the vehicle.


It also uses the same common architecture as the SAF85xx released last year, and its 28nm RFCMOS performance significantly improves radar sensor capabilities compared to previous generation 40nm or 45nm products. Tier 1 suppliers can use this new product to build more compact, energy-efficient radar sensors. Its detection range extends to 300m away, enabling more reliable detection of small objects such as curbs and vulnerable road users such as cyclists and pedestrians, bringing more comprehensive and efficient safety protection to drivers and other road users.


HELLA, a leading supplier of automotive electronics, will develop its seventh-generation radar product portfolio (including different versions of front radar, rear radar, corner radar and side radar) based on NXP's SoC family. Dr. Dietmar Stapel, Vice President and Radar Project Manager at HELLA, said: “We started working with NXP about ten years ago to develop RFCMOS-based radar sensors. Looking back at the past, we can confidently say that we chose to cooperate with NXP. is the right decision. With NXP's RFCMOS TEF81xx and TEF82xx automotive radar transceivers, we have become a major supplier of automotive 77/79GHz angular radar sensors. With NXP's range of radar SoCs, we now plan to strengthen our market presence position, providing radar solutions for all radar-supported related functions, even Level 4 autonomous driving.”


The new generation radar single chip supports NCAP safety functions, including emergency braking and blind spot detection. It also supports advanced ADAS and autonomous driving applications, including SAE Level 2+ and 3 advanced comfort features such as traffic jam assist, high-speed cruise and parking assist, front and rear cross-traffic warning, and lateral and rear collision avoidance.


The comprehensive SAF8xxx family includes the new SAF86xx and SAF85xx, which can be customized for each OEM's use case. It supports a range of sensor outputs, including object, point cloud or distance FFT-level data from edge computing sensors in today’s architectures and distributed streaming sensors in future distributed architectures.


Expanding NXP’s third generation RFCMOS radar platform

● Based on mature RFCMOS automotive radar expertise, NXP took the lead in achieving mass production and has shipped tens of millions so far.

● Highly integrated 76-81GHz SAF86xx radar SoC optimized for distributed streaming sensors with Gigabit Ethernet interface and enhanced MACsec security

● SAF86xx is developed according to the ISO 26262 Standalone Secure Element (SEooC) method and complies with ASIL Level B and ISO/SAE 21434 (as a standalone chip) standards. At the same time, it can meet new security requirements through its HSE security engine

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...
