Infineon unveils in-cabin monitoring systems for safe vehicles and roads

Fri, Jun 25, 2021

Radar sensors and microcontrollers from Infineon enable short range automotive applications in in-cabin monitoring systems (ICMS) which is reshaping passenger safety, says Infineon.

The Xensiv 60GHz BGT60ATR24C AEC-Q100 radar sensors, Aurix microcontrollers and Optireg power management ICs (PMICs) contribute to ultra-wideband (UWB), low power and cost-performance scalable architecture for ICMS sub-systems. The devices support the use of new signal processing techniques which are robust but also balance computational costs, the degree of information as well as the power consumption of the system, claims Infineon.

The Xensiv BGT60ATR24C radar sensor is a cognitive sensing device with multiple transmit/receive for virtual array configurations. There is also an agile modulation generation mechanism, automatic power mode configurability and simplified interfaces between RF and the processing side.

The Aurix TC3xx MCU family integrates a fast radar signal processing unit and enhanced security with the second-generation of the hardware security module (HSM). This includes asymmetric cryptography accelerators and full EVITA support. (The EVITA project is an EU project to design, verify and prototype suitable architectures for secure automotive on-board networks.)

Infineon has partnered with bisening, a South Korean imaging radar technology start-up, and Caaresys, an Israeli start-up to accelerate the development cycle using Infineon’s 60GHz automotive portfolio.

For example, bitsensing’s 60GHz MOD620 is enabled by advanced signal processing techniques using Infineon’s chipset. The pairing “offers a new level of confidence in safety for the automotive industry that demands excellence, reliability and unmatched intelligence,” said Dr. Jae-Eun Lee, bitsensing’s CEO.

Partner Caaresy has used Infineon’s Xensiv 24GHz and 60HHz radar sensors and Aurix MCUs in its CabinCare and BabyCare radar-based systems. It uses algorithms and radar signal processing to create aesthetic and contactless vital sign monitoring in automotives, explained CEO, Ilya Sloushch.

EPC adds 80 and 200V models to eGaN FET family

Wed, Jun 16, 2021

Two additions to the eGaN FET family by EPC address the needs of e-mobility, delivery and logistic robots and drone markets which require compact brushless DC (BLDC) motor drives and cost-effective, high-resolution time of flight (ToF).

The EPC2065 is an 80V, 3.6mOhm, 221A pulsed eGaN FET in a 7.1mm² chip scale package. The size and efficiency reduce overall power system size and weight, says EPC to make it particularly suitable for 32 to 48V BLDC motor drive applications for e-mobility ebikes and escooters, service, delivery, logistic robots and drones.

In all of these applications, miniaturisation is key and the driver is integrated with the motor in the pursuit of this. The ability to operate with significantly shorter dead times results in less noise and less EMI. eGaN FET is capable of high frequency operation to achieve what is claimed to be the highest density for high frequency DC/DC converters for computing and industrial applications and for synchronous rectification.

The second addition to the family is the EPC2054. This is a 200V, 3.6mOhm, eGaN FET in a tiny 1.69mm² chip scale package. It can deliver 32A pulsed current, despite its small size, with very fast on-off transition times and super small capacitance and inductances. These characteristics make it suitable for industrial lidar / ToF applications.

The low resistance, low switching losses, no reverse recovery charge, fast switching, high frequency capability, and the tiny footprint make the EPC2054 a cost effective and high density FET for a range of applications including high frequency DC/DC, synchronous rectification, wireless power, class D audio, automation, solar and optical.

Alex Lidow, EPC’s co-founder and CEO believes that power system designers will be able to take advantage of these latest eGaN FETs and utilize the high performance, thermally efficient small devices to replace power MOSFETs in a wide variety of applications including emobility, robotics and drones.

The eGaN FETs and related development and reference design boards are available now from Digi-Key.

Automotive window voltage monitor has BIST for ADAS

Tue, Jun 15, 2021

Built-in self test (BIST) for advanced driver assistance systems (ADAS) is included in the MAX16137 analogue supervisor. Maxim Integrated claims it is an industry-first.

The supervisor reduces the size and complexity of ADAS in vehicles, says the company, with the single-window voltage monitor with BIST.

The window monitor IC tracks both under-voltage and over-voltage levels with one per cent accuracy. This protects the ADAS and allows designers to accelerate system-wide functional safety by providing advanced diagnostics and reset capabilities.

Voltage monitors play a key role in reporting the health of power supplies for ADAS in vehicles. These systems must include test circuits to ensure reliable operation. The MAX16137 delivers both diagnostic and BIST at the chip level to help designers achieve system-wide functional safety faster for ADAS and other autonomous driving applications, says Maxim.

The MAX16137 BIST features check the supervisor functionality without the need for external circuitry, which reduces design complexity. The MAX16137 also reduces solution size by 50 per cent compared to the closest competitive solution, Maxim claims. The supervisory IC can be designed into a variety of automotive systems such as infotainment, body electronics, power, electric vehicle power powertrain and IoT systems.

The MAX16137 is available via Maxim Integrated’s website and authorised distributors. The company also offers the MAX16137EVKIT# evaluation kit.

Maxim Integrated is an engineering company for engineers. It has a broad portfolio of high performance semiconductors, combined with tools and support; it, delivers essential analogue solutions including efficient power, precision measurement, reliable connectivity and robust protection along with intelligent processing. Designers in application areas such as automotive, communications, consumer, data centre, healthcare, industrial and IoT work with Maxim to quickly develop smaller, smarter and more secure designs.

Xylon releases multi-channel HDR ISP IP suite for multiple video processing

Wed, Jun 09, 2021

For use with Xilinx programmable devices, ranging from the Artix-7 FPGAs to the latest Versal ACAP devices, the logicBricks high dynamic range (HDR) image signal processing (ISP) IP Suite enables parallel processing of multiple Ultra-HD video inputs. At the same time, it allows savings of up to 50 per cent of programmable logic in comparison to simple instantiation of multiple ISP pipelines, says Xylon.

The latest version of Xylon’s logicBricks IP suite enables crisp camera video under altering and rough lighting conditions in next-generation, multi-channel embedded systems for use in automotive, surveillance, medical and similar video and vision artificial intelligence (AI) applications.

The logicBricks HDR ISP IP suite is designed and optimised for Xilinx programmable devices.

“As the automotive industry progressively moves towards more automated driving implementations, the trend towards high resolution cameras and higher frame rates continues,” said Paul Zoratti, director of automotive solutions and system architect at Xilinx. The multi-camera ISP functionality will help automotive developers optimise cost, power, and performance in future advanced driver assistance systems (ADAS) and automated driving products, he added.

The suite’s key IP cores, the logiISP-UHD ISP pipeline and the logiHDR HDR pipeline, support parallel processing of multiple video inputs, resolutions up to 7680 x 7680 (including the popular 4K2Kp60 video resolution). It also supports the ability to merge two or three exposures, parallel pixel processing and different pixel formats. These IP cores are supplemented with automatic white balance (AWB) and automatic exposure (AE) software libraries that use video statistics data collected at the video inputs, software drivers, demo applications, reference SoC designs, and bit-accurate C models.

The HDR ISP IP suite enables application-specific tuning through modifications at different implementation stages, explained Roko Koncurat, Xylon’s ISP team lead. “The provided IP blocks can be arranged in many different ways to fully tune up the system for a specific application. While hardware engineers may configure and arrange IP blocks implemented in programmable logic in various ways, software engineers can further control the implemented ISP pipeline to adapt to changing use conditions,” he said.

The logicBricks HDR ISP IP suite can be demonstrated on different computer vision development platforms designed by Xylon. The logiREF-MULTICAM-ISP reference design is immediately available. It demonstrates parallel processing of four video camera inputs and works on the logiISP-ZU-GMSL2 evaluation kit. This kit is based on the Xilinx Zynq UltraScale+ MPSoC and includes four of Xylon’s 2.3 MP HDR logiCAM-GMSL2 automotive cameras configured to output raw Bayer video image. Xylon’s automotive cameras are Xilinx Artix-7 FPGA-based and users can re-install the HDR ISP functionality with the provided firmware and initialisation scripts.

In addition to the MPSoC-based demo kit, Xylon offers an Ultra HD reference design prepared for the logiVID-ACAP vision development kit based on the Xilinx Versal AI VCK190 evaluation kit. The reference design is developed with the Xilinx Vitis unified software platform and demonstrates parallel HDR ISP processing of three 7.4Mpixel automotive video cameras connected to the Xilinx Versal (ACAP) device.
