Bristol IC maker Xmos has added automatic vehicle number plate recognition to its algorithm portfolio. Developed with Cloudtop to run on Xmos’ xcore.ai branded silicon, the AI-based software needs no cloud connection – all processing is local – and is aimed at car parks, optimised to read slow-moving number plates at a between three and five metres range using low-cost ...

Vishay Intertechnology has introduced an AEC-Q200 qualified charging resistor “that is the industry’s first such device to feature hybrid wire-wound technology in a standard package size”, it said. “Typically, designers must utilise several thick film resistors to meet the high pulse requirements of these applications.” The parts, called HRHA, can handle 6kJ for 300ms and operate across -55 to +250°C. The ...

Allegro MicroSystems has released two automotive magnetic sensors, one for crankshafts and one for camshafts, both using the giant magnetoresistance (GMR) effect. Although both come in a simple three-pin single in-line package, they are sophisticated digital processing ICs, and system-in-packages as they also incorporate a bias magnet and EMC protection components. Crankshaft The ATS16951 crankshaft sensor is designed to be a ...

Renesas has announced what hardware it thinks will be needed for Level 2+ and Level 3 automated driving – intended for cars (automobiles) sold in 2024 and onwards. “We expect to see ADAS adopted in all vehicle types, from mid-range to entry-level,” said company automotive v-p Naoki Yoshida.” In its Level 2+ and Level 3 SoC, branded R-Car V4H, it ...

Renesas has teamed up with Tata Elxsi to build design centre for automotive products in Bangalore called ‘Nevic’ for Next Generation EV Innovation Center. They will “bring together their domain expertise intellectual property and assets to Nevic and create reference designs and solution accelerators for electric vehicle sub-systems like battery management and motor control units,” according to Renesas. “With the ...

Formerly only available in modules, Infineon is now putting its EDT2 IGBTs die into individual packaging – its TO247Plus package. The devices are optimised for automotive traction inverters and “exceed AECQ101 for automotive components”, claims the firm. “With the automotive micro-pattern trench-field-stop cell design, the IGBTs are based on technology that has already been utilised in inverter modules such as ...

Renesas and Fixstars are collaborating on automotive deep learning – establishing a laboratory to support early development and operation of driver-assistance and autonomous driving systems. “Fixstars possesses both software for deep learning and optimisation technology that allows more efficient utilisation of hardware,” said Renesas automotive v-p Takeshi Kataoka. “I am confident that our collaboration will enable us to provide support ...

Green Hills Software has teamed up with NXP to support driver assistance radar image processing. NXP is providing the hardware: the 16nm S32R45 imaging radar processor, while Green Hills is providing its Integrity real-time operating system (RTOS) and software development tools. “Common software and hardware architecture spanning the S32R45 and S32R41 radar processors enables OEMs and Tier 1s to develop ...

Diodes has launched a series of automotive-compliant synchronous buck converters for delivering up to 3A in automotive point-of-load converters in 3 x 2.8mm TSOT26 packages With 2A and 3A ratings, AP6320xQ and AP6330xQ respectively can operate with inputs from 3.8 to 32V and over -40 to +125°C. 3A versions integrate 70/40mΩ (high/low-side) mosfets, or 125/68mΩ for the 2A parts. There are six devices AP63200Q 2A, Vout ...

Murata has managed to compress 4.3μF into a three-terminal 0402 (1005 metric) package, and qualified it for automotive use. This is the surface-mount equivalent of a feed-through capacitor, with the end terminals connected together by a low-resistance direct path. This path is one end of the capacitor, whose other end is to be grounded via the centre terminal (which looks ...
