Renesas unveils family of automotive radar transceivers with high accuracy and low power consumption

Fri, Nov 18, 2022

Renesas Electronics Corporation is entering the automotive radar market with the introduction of a 4×4-channel, 76-81GHz transceiver designed to meet the requirements of ADAS (advanced driver assistance systems) and Level 3 and higher autonomous driving applications.

Renesas will incorporate the new RAA270205 high-definition radar transceiver into its growing sensor fusion portfolio, which combines radar, vision systems, and other sensing modalities.

Designed in co-operation with Steradian Semiconductors Private Limited, which Renesas acquired earlier this year, the new transceiver MMIC (monolithic microwave integrated circuit) is especially suited for imaging radar, long-range forward-looking radar and 4D radar, but can also be used for corner and central-processing radar architectures, the so-called ‘satellite’ automotive radar systems, said the company. Equipped with 4Tx and 4Rx channels, the RAA270205 supports up to 16 MIMO (multiple-input and multiple-output) channels. It can be cascaded to enable higher channel count and better radar resolution.

The RAA270205 features up to 5GHz of bandwidth and a 112.5MSPS ADC (analog-to-digital converter) sampling rate that it claims is nearly three times faster than those of competing devices. Power consumption of 1.2W is 50 per cent lower than that of comparable transceivers and it delivers a noise figure of 9dB, which is 3dB less than other radar transceivers, it says. Its chirp rate of up to 300MHz/microAs improves radar resolution and object detection.

“Today’s radar transceiver MMICs must achieve higher definition to support the high-accuracy requirements of ADAS and autonomous driving safety platforms,” said Vivek Bhan, senior vice-president and deputy general manager of Renesas’ automotive solution business unit. “Working in close collaboration with Steradian, which brings deep radar design expertise, we are expanding our sensor fusion offerings with a focus on functional safety and low power consumption to help our customers lower their development costs and improve time to market.”

Renesas plans to combine the RAA270205 transceiver with other compatible devices from its portfolio to support automotive radar systems. These combinations will include the satellite radar system for AD/ADAS, which will be available in Q2/2023.

The RAA270205 will be available in 1Q/2023 in sample quantities, with commercial production planned for 2024. The transceiver is available in a small, easy-to-integrate eWLB (embedded wafer-level ball-grid array) package, measuring 7.6×5.6mm. It will be fully compliant with automotive industry requirements such as IATF 16949, AEC-Q100 Grade2 and ASIL B.

NeoCortec P Series NeoMesh wireless module can be integrated to PCBs

Fri, Nov 18, 2022

NeoCortec, manufacturer of bi-directional wireless mesh network modules, has released its P Series of wireless NeoMesh modules. Featuring an RF/IO antenna connection placed under the module on solder pads for quick and easy soldering to any PCB, the company claims the P Series modules allow for a more efficient antenna design as well as more compact design of the sensor or actuator and allow customers to integrate Neocortec’s NeoMesh modules into their own PCB with the antenna also already integrated.

The new NeoMesh modules, NC1000P-8, NC1000P-9 and NC2400P, operate at 868MHz, 915MHz and 2.4GHz respectively and complement the C-Series modules that come with an u.FL connector and are used whenever an external connector is wanted. Cost efficient and easy to integrate, all the modules from NeoCortec suit a broad range of applications based on IoT and Cloud-based sensor networks, including smart home and smart workplace, metering, security, agriculture, transportation, Industry 4.0, medical and food distribution.

NeoMesh from NeoCortec is a protocol enabling node-to-node mesh communication of sensors, without any need for mains-powered devices. All devices can be battery-powered, as can the gateway. To start building the network, simply switch on two nodes. When switched on additional nodes will automatically join the existing network and will start expanding it in a number of devices in range. The NeoCortec communication modules are equipped with radio and NeoMesh and can easily be integrated in a sensor or motor.

NeoCortec is a supplier of ultra-low-power bi-directional wireless mesh network modules. NeoCortec is based in Copenhagen, Denmark.

NXP analogue front-end enables the software-defined factory

Thu, Nov 17, 2022

NXP Semiconductors is aiming the NXP analogue front-end (N-AFE) family at high-precision data acquisition and condition monitoring systems for factory automation. Designed as software-configurable universal analogue input devices, the N-AFE family helps enable the software-defined factory, making it easier for operators to configure a smart factory and adjust settings based on shifting market needs.

Even as factories have become smarter over time, adapting to rapidly shifting market trends has remained a challenge, often requiring large-scale equipment overhauls to reconfigure a factory to meet a new need. The addition of software-configurable components allows factory operators to be more nimble, enabling them to more quickly and easily make changes to the factory floor to address rapidly shifting trends, said NXP.

Software-defined factories are the next evolution of the Industry 4.0, and this software-configurable analogue front-end family will help achieve that milestone, said Jens Hinrichsen, executive vice-president and general manager of advanced analogue at NXP. By combining configurability with enhanced accuracy and precision for improved product quality, as well as advanced diagnostics to identify issues before they occur to reduce downtime, this device enables a new era of the smart factory, he claimed.

Schneider Electric has worked closely with NXP to incorporate the N-AFE family into its industrial solutions. The single-chip N-AFE solution helps to reduce the complexity of hardware design for the company, whose industrial customers benefit from the software configurability delivered by the N-AFE.

“The impact of a software-defined factory, both in terms of productivity and overall costs saved, is immeasurable,” said Ralf Neubert, vice-president, research & development, digital factory, at Schneider Electric. “NXP’s new analogue front-end software configurability and high precision accelerate hardware design improve time to market. The N-AFE family enables flexibility in our designs to allow our customers to quickly respond to market trends, but more importantly, it also helps to reduce unplanned downtime, enabling a more productive factory overall.”

The N-AFE family of devices integrates up to eight universal analogue inputs at a lower system cost for data acquisition systems in factory and process automation. It combines signal chain protection, precision amplification and high-speed data conversion, filters and self-diagnostics to monitor factory conditions, helping to ensure a more consistent and repeatable quality of product. The device also integrates additional advanced diagnostics to reduce factory downtime with predictive maintenance and anomaly detection, while its factory calibration and self-calibration features help reduce test costs, it said.

The addition of the N-AFE analogue front-end family of devices brings new analogue capabilities to NXP’s portfolio targeting industrial applications. Combined with NXP’s MCU and power management portfolios, including devices such as the i.MX RT1180 high-performance crossover MCU and PF5020 and PCA9460 power management ICs (PMICs), the N-AFE devices expand the industrial system solution offering.
