Automotive Echo Cancellation Available for NXP Processors

NXP Semiconductors has announced a new echo cancellation noise reduction solution (ECNR) that significantly reduces the problem of noisy voice communications and provides carmakers with a consumer pleasing, hands-free calling experience. The cost-effective solution combines innovative ECNR software that can be easily ported onto NXP i.MX processors and NXP’s leading car radio tuners and DSPs. The new NXP ECNR solution is also ITU-T P1110 and CarPlay pre-certified.
Echo and noise can make communication on the road difficult. Echo occurs when the speakers within a car transmit a voice signal from an incoming call, which subsequently ricochets through the vehicle and returns to the microphone. This causes the caller to hear their own voice, which is distracting and can result in broken communications. Additionally, road noise from fans, exhaust, tires, windows and passengers can infiltrate calls and render them unintelligible, ultimately disrupting the driving experience and causing frustration.

The new NXP ECNR solution deals with both problems by removing echoes and filtering out unwanted noise from the cockpit to enhance the sound quality of conversations. Since the ECNR solution can be ported to NXP chipsets and is ITU-T P1110 and CarPlay pre-certified, it can reduce carmakers’ R&D expenses and speed up the design cycle.

NXPs SAF775x integrates up to 2 AM/FM tuners, radio processing, an automotive audio hub and an open HiFi2 core for advanced audio algorithms. SAF775x has rich analog and digital interfaces, flexible audio mixer and filter structure, and core audio processing algorithms. The SAF775x family radio-audio one chip is a market-proven solution and has been successfully designed in major automotive OEM platforms.

i.MX applications processors offer a feature and performance-scalable multicore platform that includes single, dual and quad-core families based on the Arm® v7-A and Arm v8 architecture based solutions with powerful processing for neural networks, advanced graphics, machine vision, video, audio, voice and safety-critical requirements.

The ECNR algorithm is running on the HiFi2 core of SAF775x, ready be activated by a key code.

Step-Down Converters Target Always-On Car Systems

Maxim Integrated Products has announced the ultra-compact, pin-compatible MAX20075 and MAX20076 step-down converters that enable system designers looking to create small and highly efficient 40-V load dump-tolerant applications. The MAX20075 and MAX20076 step-down converters offer low quiescent current (IQ) and feature integrated compensation. This enables minimal external components that can lead up to 50% savings in board space making them well-suited for always-on automotive applications.

According to Maxim Integrated, car customers expect always-on applications to bring them experiences richer and more compelling than ever before. However, car system designers are challenged with having to balance delivering advanced features with meeting size constraints, power-saving features and high efficiency.

The MAX20075 and MAX20076 in peak current mode draw just 3.5 µA in the low power operating mode, which is key to meeting the stringent OEM IQ consumption requirements of 100 µA per module. The converters enable low noise operation via pin-controlled spread spectrum and fixed 2.1 MHz operation to meet CISPR 25 Class 5 EMI compliance. Furthermore, added advantage of the 2.1 MHz operation and internal compensation is that it lowers the solution size and the bill of materials (BOM) compared to a non-synchronous device that operates in the AM band.

The MAX20075 and MAX20076 are available with a low minimum on-time mode operation, which allows the converters to support large input-to-output conversion ratios. For example, Vbatt input to Vout of less than 3 V at 2.1 MHz; this translates to not having to use a secondary supply, which reduces overall BOM cost by $0.30 to incorporate new functions into the design for greater flexibility. The MAX20075 and MAX20076 meet AEC-Q100, are available in a 3 mm x 3 mm TDFN package, and operate over the -40°C to +125°C temperature range.

Infineon MCUs Serve Audi’s Autonomous Car Functionality

Infineon Technologies has announced that it supplies key components for the Audi A8, the first series production car featuring level 3 automated driving. The ability of cars to self-drive is split into a number of different levels: With level 3, drivers can temporarily take their hands off the steering wheel under certain conditions.  The Audi A8 allows this when parking and exiting, in slow-moving traffic or in traffic congestion. Using microelectronics from Infineon Technologies, a car can take over in this kind of driving situation.

Various types of chips from Infineon serve the safe automated driving in the Audi A8: sensors, microcontrollers and power semiconductors. Radar sensor chips from the RASIC family are installed in the front and corner radar. They send and receive high-frequency 77-GHz signals and forward these on to the central driver assistance controller (zFAS).

A microcontroller from the AURIX family is a key component of the zFAS for reliable automated driving. AURIX enables to secure the connection to the vehicle data bus. It assesses and prioritizes data packets and initiates their processing in the fastest possible time. For example, it initiates emergency braking based on data from radar and other sensor systems. The AURIX family of microcontrollers is especially ideal for this purpose thanks to high processing power and extensive safety features.

AURIX microcontrollers are used in several controllers in the Audi A8: On the one hand, they control the functions for the engine. On the other, they operate in the Audi AI active chassis and in the electronic chassis platform, which controls the shock absorption. The microcontrollers also support activation of the airbag.

In addition to the electronics for drive, driver assistance and chassis, other semiconductor solutions from Infineon are installed in the comfort and body electronics, such as for example LED drivers from the LITIX Basic family in the tail lights as well as bridge drivers from the Embedded Power family in the windscreen wipers.
