Starter kit for R-Car S4 speeds up prototyping software development

Wed, Jul 12, 2023

A development board for automotive gateway systems is now available from Renesas. The R-Car S4 starter kit is an inexpensive, development board for building software using the Renesas R-Car S4 SoC.

The SoC delivers high computing performance and an array of communication features for both cloud communication and safe vehicle control. The starter kit is less expensive than the earlier R-Car S4 reference board, which provides a development environment including an evaluation board and software. Engineers can use the kit to start the initial evaluation of car servers, connected gateways, connectivity modules for rapid application development.

The R-Car S4 starter kit includes essential R-Car S4 interfaces such as Ethernet TSN switch and CAN FD, as well as memory such as 4Gbyte of LPDDR4, 128Gbyte of UFS (Universal Flash Storage), and 64Mbyte of Quad SPI flash memory. Users can expand peripheral functions by using expansion connectors and customise the hardware to meet specific application requirements, advised Renesas.

The R-Car S4 Whitebox software development kit is an open source automotive development environment for the R-Car S4, which can be combined with the R-Car S4 starter kit. The software development kit consists of FoC (free of charge) software and can be used without the need for complicated license agreements. The software development kit (SDK) includes sample software, test programs, and resource monitoring tools for OTA (over-the-air software updates), IPS (intrusion prevention system), and IDS (intrusion detection system) for network security, allowing for various prototyping and evaluation.

There is also sample software which can be used as a base to develop applications. According to Renesas, the kit shortens development time and reduces energy consumption.

The R-Car S4 starter kit is available from major distributors or via a Renesas local sales representative.

The R-Car S4 whitebox SDK will be available by the end of August.

High density cryogenic connector delivers quantum computing

Wed, Jul 12, 2023

The Q-CON high density cryogenic connector has been developed to meet demand for quantum computing, and the development of large-scale high qubit machines which require microwave cables for control and readout lines to the quantum processor.

These have traditionally been individual coaxial cables fitted with SMA connectors which offer limited packaging due to their 8mm hex coupling, explained CryoCoax, a division of Intelliconnect (Europe). The cables also require space in order to provide access for tooling during installation.

CryoCoax has developed high density, multi-way connectors based around the SMPM micro miniature interface. This provides many more coaxial lines in a given space, said the company but also simplifies the installation and customisation within a dilution refrigerator. Typical spacing using SMA connectors is limited to approximately 16mm, whereas the Q-CON high density connectors are designed with a pitch of 4.75mm. The SMPM interface provides a simple push to mate connection only requiring a hex key to tighten the two fasteners.

The connector components are machined from high purity copper and beryllium copper and are gold plated to optimise thermal conductivity. Non-magnetic versions can also be specified if required.

The connectors are compatible with 0.047-inch (1.19mm) size coax, and either semi-rigid, flexible or conformable versions are available. Semi-rigid cables are available in niobium titanium, stainless steel, copper, cupronickel and beryllium copper as well as combinations of these with silver plated conductors, providing a choice in terms of thermal conductivity and attenuation.

To minimise passive heat load, cable materials with low thermal conductivity are normally favoured, however, with the exception of superconductors this typically goes hand in hand with poor electrical conductivity. Flexible cables with silver plated copper conductors are typically used for connections from the top of the dilution refrigerator to connect the control electronics at room temperature and can be terminated with conventional SMA connectors. Conformable copper coax options are also available and are often used at the lowest stage.

Superconducting niobium titanium cables are often specified in quantum applications this material can be challenging, if not impossible, to solder. To overcome this, CryoCoax developed solderless connections for these high-density connectors as well as the traditional SMA, 2.92 and SMP connectors.

Standard configurations of the Q-CON high-density connectors are eight-way, 16-way and 24-way with either smooth bore or full detent options, connector blocks can be ganged together to potentially give hundreds of coax lines in a dilution refrigerator. Two connector blocks form a mated pair, one having a full detent male SMPM interface, and the other a smooth bore SMPM male interface, are used in conjunction with ‘bullet’ style female to female SMPM adaptors fitted between a pair of connector blocks.

The ‘bullet’ adapters are retained in the full detent connector block. These can be combined with eight-way, 16-way and 24-way attenuator blocks available in 0dB, 3dB, 6dB, 10dB and 20dB. CryoCoax worked with an attenuator manufacturer to develop these attenuator blocks to complement the high density connectors. Attenuators are employed to suppress thermal noise and provide thermalisation of the centre conductors.

The company specialises in cryogenic connectivity used for quantum computing, research, test and measurement and medical applications.

N-type antenna connectors meet MIL-STD-348

Mon, Jul 10, 2023

The latest addition to the Würth Elektronik portfolio of coaxial cables and connectors is a range of N-type cable connectors which satisfy MIL-STD-348 requirements with 50 Ohm impedance.

The series includes jacks for connecting to the application PCB, available in straight and angled THT versions, or as four-hole flanged panel connectors with round post or solder cup. In addition to pre-assembled cables, individual cable connections are also available for field assembly.

The Würth Elektronik coax connectors are suitable for use outdoors or in harsh environments, for example radio base stations, signal distributors, GPS systems or ship antennas. The screw connections of the THT jacks as well as those for mounting packages are available in protection class IP67. The gold-plated THT contacts have enhanced corrosion resistance compared to the standard tin-plated connectors, and the gold-plated phosphor-bronze centre contact material reduces component costs compared to using beryllium-copper said Würth Elektronik.

There are also various assembled cables available including double shielded Low Loss 195 and Low Loss 200, which are compatible with LMR195/200 or CFD195/200. The RG316 cable with FEP sheathing, for example, is resistant to oil, chemicals and weathering and can be used at operating temperatures from ‑55 to +165 degrees C.

The N-type cable connectors are designed for quick installation of cable assemblies in small quantities and for assembly in the field. The secure screw connection is achieved using the knurled union nut. Both the IP67 and RG178 bulkhead jack are also suitable for micro coaxial cables (1.3, 1.32 and 1.37).

The new coaxial products also include N-type to SMA adapters, required for connection expansion and for adapting RF interfaces or for test equipment.

The coax connectors, are available from stock. Free samples can be requested.

Würth Elektronik eiSos Group manufactures electronic and electromechanical components. It is one of the largest European manufacturers of passive components and is active in 50 countries and has production sites in Europe, Asia and North America.
