ST Microelectronics has extended its multi-year silicon carbide wafer deal with Cree, taking it to over $500m in total value. Cree will supply 150mm bare and epitaxial silicon carbide wafers to ST over “several years”, according to Cree. “Expanding our long-term wafer supply agreement with Cree will increase the flexibility of our global silicon carbide substrate supply,” said ST CEO Jean-Marc ...

Built using Texas Instruments low power, 45nm RFCMOS process, the AWR1843 is the latest wideband mmWave sensor available from Mouser Electronics.  It is AEC-Q100-qualified for automotive design, where its small form factor is suitable for radar systems in vehicles.  According to the distributor, the RFCMOS process enables a monolithic implementation of a system with three transmit and four receive channels, ...

Taiwan Semiconductor has introduced 45V and 60V trench Schottky rectifiers in a TO-277A-compatible SMPC4.6U package, and qualified to AEC-Q101 for the automotive market. The surface-mount package is only 1.1mm high and has wettable flanks for automated optical inspection. The parts are TSUPxM45SH or TSUPxM60SH, depending on whther the current rating is 45A or 60A, and the ‘x’ needs to be replaced with ...

Allegro has introduced a dc-dc converter designed for keep-alive duties in cars. Automotive AEC-Q100 qualified, it will operate with inputs from 3.5 to 36V (withstanding 40 V load dump surge) and draws just 8μA when maintaining 3.3 or 5.0V on the output. Called ARG81800, two versions are available: 500 mA and 1 A, to allow smaller PCBs for lower power systems as ...

Vishay is aiming at position tracking in virtual reality headsets and augmented reality glasses with a set of surface-mount infra-red LEDs. They are: VSMY5850X01 (850nm) VSMY5890X01 (890nm) VSMY5940X01 (940nm) and deliver 30% greater radiant intensity than the firm’s prior-generation devices, and operate over -40°C to +110°C. “Ideal for position tracking in virtual or augmented reality applications, these emitters help simplify ...

Electromechanical component distributor, Foremost Electronics, has added switching products from Elma Electronics to its linecard. These include the X4 and  MR50 rotary switches. The former is a designed for the toughest requirements, says the company, and has an optional pushbutton function. The switch incorporates a magnetic, Hall effect (contactless) sensing system for rugged, reliable, long life operation. The microcontroller-based circuitry ...

Wind River and Xilinx are co-developing an automated driving platform using Wind River’s  automotive software and Xilinx’s ACAP chip. The collaboration will provide carmakers with a flexible compute platform for delivering connected and automated driving vehicles. The platform will deliver the foundation to enable a software architecture approach needed for autonomous driving applications, and make integration nearly plug and play. The ...

Xilinx has expanded its automotive-qualified 16nm family with two new devices – the Xilinx Automotive (XA) Zynq UltraScale+ MPSoC 7EV and 11EG. These two new parts deliver the highest programmable capacity, performance and I/O capabilities enabling high-speed, data aggregation, pre-processing, and distribution (DAPD), as well as compute acceleration for L2+ to L4 advanced driver-assistance systems (ADAS) and autonomous driving (AD) applications. ...

Californian chip-maker Blaize has emerged from stealth development with a processor aimed at artificial intelligence. Until recently called Thinci, the El Dorado Hills firm describes its product as “the first true graph-native silicon architecture and software platform built to process neural networks and enable AI applications with unprecedented efficiency”. Unfortunately: “we are not disclosing any metrics yet”, Blaize v-p of ...

Allegro is claiming isolation up to 1.3kV dc (650V reinforced) for a series of current sensors that work up 400A (ac and dc) and respond in 2.5µs for fast over-current detection. Safety-critical applications such as vehicles and robotics are the target. ACS772 is a 200kHz bandwidth automotive grade current sensor for 50 to 400A, with 100μΩ internal sensing for low power ...
