GigaDevice has revealed a family of 48MHz Arm Cortex-M23 microcontrollers. Aimed at industrial use GD32C231, its “Cortex-M23 core architecture offers up to 10% higher performance than Cortex-M0+”, according to the company. 32 to 64kbyte of flash and 12kbyte or ram are available, all with error correction. “An integrated hardware CRC module enhances data transmission integrity,” according to the company, which ...
Infineon has introduced automotive microcontrollers with capacitive touch sensing for sensor and actuator applications. The PSOC 4 HVMS family is built around a 24 or 48MHz Arm Cortex-M0+ processor, with up to 128kbyte of flash and 8kbyte of ram. The ICs also have what Infineon calls ‘high-voltage’ capability for almost-direct connection to 12 and 24V vehicle batteries as they include an ...
Did you ever dream of surface-mounting wire-wound power resistors? If you do, Vishay has turned that into reality with a series of pick-and-place-friendly cemented wire-wounds. They are actually the company’s existing 3W AC03-CS series of fuseable resistors, with the legs bent into what the company is calling its WSZ lead-form (see photo), available from 1Ω to 100Ω ±5%, with ±200ppm/°C ...
Software company Vector has gained ISO/SAE 21434 certification for its vehicle hardware security modules firmware. ISO/SAE 21434 sets cybersecurity risk limits for road vehicles throughout their life cycle. The firmware is called Microsar HSM, and it was certified using Infineon Aurix TC3xx MCUs, which have Infineon’s proprietary TriCore cores. “The ISO/SAE 21434 certification of Microsar HSM confirms the use of ...
China’s rare earths export ban is to beginning to affect car production, reports the Nikkei. Suzuki has suspended production of its Swift models. Ford has suspended production of its Explorer sports SUV at its Chicago factory. The European Association of Automotive Suppliers (CLEPA) says some auto component makers have been forced to close plants. India’s Bajaj Auto said the magnet ...
Arm has pre-integrated intellectual property for designers of AI-defined vehicle ICs. “Capabilities like real-time driver monitoring, predictive maintenance and adaptive in-vehicle infotainment, that were once limited to premium models, are becoming the standard across all tiers of new vehicles,” according to the company. “At the same time, automotive development complexity continues to grow, with evolving safety requirements and increasing demands ...
The GMSL serial bus is to be standardised as OpenGMSL with the formation of an industry body to be called the OpenGMSL Association. It will also style itself ‘OGA’. “With a standard for video and high-speed data transmission based on ‘gigabit multimedia serial link technology’, adoption and innovation of the OpenGMSL standard will reshape autonomous driving, driver assistance systems and ...
Lighter connectors contribute to reduced overall system mass, which is particularly important in weight-sensitive applications such as aircraft, satellites and drones, explains John Brunt. Reducing the weight of connectors and cables in applications such as aerospace, electric vehicles (EVs) and space systems is crucial for enhancing performance, fuel efficiency and overall system reliability. Connectors are generally heavier than other components ...
Not known for making microcontrollers, Allegro Microsystems has picked a 40MHz Arm Cortex-M4 as the processing heart of a series of stand-alone three-phase automotive brushless motor driver ICs for rails up to 90V. The parts are: 60V motor, 5.0V I/O, 252kbyte flash A89211GEVSR 60V motor, 3.3V I/O, 128kbyte flash A89211GEVSR-A 90V motor, 5.0V I/O, 252kbyte flash A89212GEVSR 90V motor, 3.3V ...
Rhopoint Components is to supply a 1.2kV 260A three-phase silicon carbide power module for electric vehicles. Made by Cissoid and called CMT-PLA3SB12340, it can supply its 26A at 90°C, and up to 340A at 25°C. This is a complete power module, including output-to-baseplate (5kVdc for 1min) and input-to-output (3kV for 1min) isolation, power supplies to feed the secondary side gate ...
