Nexperia has introduced a 110V 4A half-bridge gate driver IC. “NGD4300 has been designed for use with dc-dc converters in consumer devices, servers and telecommunications equipment as well as for micro-inverters used in various industrial applications,” according to the company, which is also producing an automotive-qualified version: NGD4300-Q100 for power steering, for example. 4A is the peak sourcing current, and ...

At the Arm Tech Symposia, in Tokyo, this week, Arm announced a partnership with Panasonic to standardise the automotive architecture for software-defined vehicles (SDVs), with a future-proofed software stack. The partners have demonstrated a proof-of-concept using PAS’s open-source remote GPU technology, Unified HMI, to implement a Display Zonal architecture built on Arm which distributes GPU loads from the central ECU ...

Infineon has added post-quantum cryptography support to 28nm 500MHz automotive processors. Called Aurix TC4Dx, they are rated for ISO/SAE21434 cyber security standards, and are the first members of the first member of the TC4x. They have six cores, with lock-step operation for high-level functional safety – ISO26262 ASIL-D is the target. “With its parallel processing unit, the microcontroller provides a ...

Japanese automotive component supplier Denso, has signed a development license agreement with Californian startup, Quadric for a neural processing unit (NPU). The agreement means Denso will acquire the IP core license for Quadric’s Chimera general purpose NPU (GPNPU). Both companies will co-develop IP for an in-vehicle semiconductor for use in intelligent vehicle systems (ADAS and AD/self-driving) and inter-vehicle and cloud ...

Vishay has introduced an automotive-rated series of positive temperature coefficient (PTC) in-rush current thermistors that can absorb up to 340J, designed for dc link charging and energy discharge circuits. Called PTCEL67R, they are through-hole disc devices, available with 25°C resistances (R25 values) from 150Ω to 1.5kΩ and handling up to 1.2kVdc. They can handle 180J at 85°C and 130J at ...

Silicon timing boosts automotive reliability and safety, and is essential for autonomous driving, says Sumeet Kulkani. Four major trends are shaping the future of transportation. These are electrification, shared ownership, active safety systems and driving automation. They are having a major impact on the way vehicles are being designed, demanding more digital systems on board to handle aspects such as ...

As autonomous driving systems advance, ensuring functional safety becomes increasingly critical. ABLIC Inc, a manufacturer of analog semiconductors with over 20 years of experience in automotive electronics, offers insights into this complex issue from a component-level perspective. Pursuing Zero Accidents in Autonomous Driving Autonomous driving systems aim to reduce accidents caused by human error. However, as operational conditions expand and ...

Ten companies – Imec, Arm, ASE, BMW, Bosch, Siemens, SiliconAuto, Synopsys, Tenstorrent and Valeo  – have now joined an Automotive Chiplet Program (ACP) to evaluate which chiplet architectures and packaging technologies are best for automotive applications. “The adoption of chiplet technology would signal a disruptive shift in central vehicle computer design, offering distinct advantages over traditional monolithic approaches. Chiplets facilitate ...

For electronic control units (ECUs) built around Infineon TriCore or Aurix processors, and Vector’s ‘Microsar Classic’ software, Vector has teamed up with development tool company PLS to created a timing bundle “which can be used to identify and eliminate timing problems in early project phases”, according to PLS. Available from Vector, it combines PLS’ UDE (‘universal debug engine’) and Vector’s ...

Toshiba has got together with development board maker Mikroe to create a platform for its TB9M003FG automotive three-phase motor control and driver IC. AEC-Q100 Grade 0 qualified, the IC has a 32bit 40MHz Arm Cortex-M0 CPU and a vector co-processor  for sensorless vector control, as well as gate-drivers to control external n-channel mosfets. AEC-Q101 qualified mosfets are included on the ...
