Skyworks releases switches for automotive and comms

Thu, Sep 23, 2021

Automotive switches and low-noise amplifier front-end modules from Skyworks are designed for automotive, cellular compensator and cellular telematics applications.

The company has released four devices, the SKYA21038, SKYA21039, SKYA210140 and SKYA21041.

The SKYA21038 is a single pole, double throw (SPDT) switch intended for mode switching in WLAN applications. Switching technologies enable the SKYA21038 to maintain a low insertion loss and high isolation for all switching paths, says Skyworks. The high-linearity performance and low insertion loss mean that the switch is suitable for low power transmit / receive applications.

The switch is manufactured in a compact, 1.0 x 1.0 x 0.5mm, six-pin exposed pad plastic micro leadframe package dual (MLPD) package.

The SKYA21039 is a single pole, triple throw (SP3T) antenna switch that operates in the 2.4 to 2.5GHz frequency range. Switching between the antenna (RFC signal) and the RF1, RF2, and RF3 ports is accomplished with two control voltages (V1 and V2). Characteristics of low loss, high isolation, high linearity, small size, and low cost make the switch suitable for all WLAN and Bluetooth systems operating in the 2.4 to 2.5GHz band. The SKYA21039 is manufactured in a compact, 1.1 x 1.1 x 0.5mm, eight-pin Micro Leadframe (MLP) package.

The SKYA21040 integrates a single pole, triple throw (SP3T) switch and low noise amplifier (LNA) with a bypass mode in a compact package. The device is capable of switching between WLAN receive, WLAN transmit, and Bluetooth and is provided in a small dual flat no-lead (DFN) eight-pin, 1.5 x 1.5mm package.

The fourth switch is the SKYA21041 which integrates a single pole, double throw (SPDT) switch and low noise amplifier (LNA) with a bypass mode in a six-pin, 1.2 x 1.4mm DFN package. It is capable of switching between WLAN receive and WLAN transmit.

R-Car development kit assembles tools for deep learning in vehicle design

Wed, Sep 22, 2021

Software development and validation for smart camera and automated driving applications in passenger, commercial and off-road vehicles can be accelerated using the R-Car software development kit, says Renesas Electronics. The single, multi-OS software platform is easy for customers to access, learn, use, and install, claims the company.

Deep learning is being used by vehicle manufacturers to enable smart camera applications and automated driving systems. Most however are built on consumer or server applications, which do not operate under the same stringent constraints for functional safety, real-time responsiveness, and low power consumption.

Optimised for use with Renesas’ R-Car V3H and R-Car V3M SoCs, the R-Car SDK is built for rule-based automotive computer vision and AI-based functions. The simulation platform offers both AI and conventional hardware accelerators for accurate simulations in real time. Renesas has already confirmed that it will continue to strengthen this virtual platform. A full suite of development PC-based tools is delivered for both Windows and Linux as well as multiple libraries, including support for deep learning, computer vision, video codecs, and 3D graphics. The SDK supports Linux, multiple ASIL-D-compliant operating systems (e.g., QNX, eMCOS, and Integrity) in a single package.

A version of the e² studio is available for the R-Car V series, focusing on the creation of real-time computer vision applications for ADAS and automated driving. The open-source Eclipse-based development environment includes a full set of debug features and an e² studio GUI (graphics user interface) that allows users to customise and integrate third-party tools. It also supports bus monitoring and debug functionalities for image processing and deep learning subsystems.

Software samples, popular CNN networks, a workshop, and application notes are included for a quick start for development. The SDK is also suitable for benchmarking Renesas products and to select the most appropriate SoC for a target application.

The automatic installer ensures all the software libraries and the development environment can be launched quickly on a development workstation. Applications developed and designed on a PC can be seamlessly ported to embedded development hardware. Renesas’ R-Car partner ecosystem – the R-Car Consortium – will have access to the R-Car SDK.

The R-Car SDK is available now.

SOAFEE brings cloud-native design to vehicles, says Arm and partners

Thu, Sep 16, 2021

To address the software-defined needs of cars today quickly and seamlessly, a standardised framework will enhance proven cloud-native technologies that work at scale with the real time and safety features required in automotive applications. The same framework can also benefit other real -time and safety critical applications, such as robotics and industrial automation.

Vehicle manufacturers, system integrators, semiconductor manufacturers, software developers and cloud technology companies have worked together to define SOAFEE (Scalable Open Architecture for Embedded Edge), for the software-defined vehicle. The SOAFEE reference implementation will be free open source software aimed at allowing broad prototyping, workload exploration and early development.

Building on Project Cassini and SystemReady from Arm, which enable a standards-based cloud-native experience at the edge, SOAFEE enables cloud concepts like container orchestration with automotive functional safety and in real time. Arm said it is working with commercial solutions providers to maximise compatibility and provide a faster route to functionally safe designs.

The immediate availability of SOAFEE will empower cloud-based developers to apply their expertise and contribute to vehicle electronics and software-architecture requirements, and driving the industry to a software-centric future.

“At AWS, we’re committed to innovation with key industry players like Arm to help solve complex challenges for delivering software-defined vehicles with a service-oriented architecture,” said Bill Foy, director, worldwide automotive business development at AWS. “In collaboration with Arm, and AWS’s Arm-based AWS Graviton2 instances, we . . . make it possible to run applications on the same architecture in the cloud and at the automotive edge to simplify developer workflow.”

AdLink’s new SystemReady-compatible development platform is powered by Arm Neoverse-based Ampere Altra cores and will allow workload exploration and development on Arm-based silicon using the SOAFEE reference software stack for applications such as cockpit, ADAS, powertrain and autonomous driving. The development platform comprises a developer workstation and a rugged in-vehicle product. It is available for pre-order, with general availability expected in Q4 2021.

Also announced today are the AVA developer platform – a 32-core scalable compute system built for lab-based development. It is capable of running autonomous workloads and allows developers to leverage accelerator hardware to complement CPUs.

For in-vehicle prototyping and testing, the AVA-AP1 has 80 cores for increased CPU performance, extra I/O capabilities and a safety processor to enable in-vehicle execution using real sensors.

In addition to support from AWS, ADLink, Ampere and CARIAD, the initiatives have received broad support from leaders across the supply chain including Apex.AI, Continental, Green Hills Software, Linaro, Marvell, MIH Consortium, Red Hat, SUSE, Woven Planet and Zing Robotics.

Reference design blends Renesas AHL and OmniVision SoC for vehicle cameras

Wed, Sep 15, 2021

Automotive HD Link (AHL) technology from Renesas and OmniVision’s OX01F10 SoC are used in an integrated reference design for automotive camera systems. The two companies have developed the reference design in which AHL technology transmits HD video over low-cost cables and connectors. The AHL components pair with OmniVision’s OX01F10 1.3MP SoC, which is claimed to provide the industry’s best imaging performance across a wide range of challenging lighting conditions. It is also compact and has low power consumption, said OmniVison.

The new RAA279971 AHL encoder and RAA279972 decoder use a modulated analogue signal to transmit the video, enabling transmission rates 10 times less than required to transmit HD signals digitally. The lower transmission rate means that unshielded twisted pair (UTP) cables and standard low-cost connectors can be used, as can existing traditional analogue video cables and connectors.

Renesas added that AHL can be paired with other Renesas products, such as the R-Car Automotive SoCs, RH850 MCUs, automotive PMICs, and analogue components to implement numerous safety features in virtually any vehicle.

OmniVision’s OX01F10 SoC integrates a 3.0 micron image sensor and an image signal processor (ISP) with OmniVision’s PureCel Plus technology for low noise, solving the automotive rear view camera and surround view system challenges of achieving a small form factor with low-light performance, low power and reduced cost while improving reliability by enabling single PCB designs.

The 1.3MP OX01F10 supports HDR up to 120dB and the sensor features ASIL-B.

The reference design will be demonstrated at OmniVision’s booth #15 at AutoSens Brussels 2021 Exhibition, September 15 to 16.

The reference design is available through both Renesas and OmniVision.
