Renesas Unveils First Family of Automotive Radar Transceivers with Industry’s Highest Accuracy and Lowest Power Consumption

Renesas Electronics Corporation, a premier supplier of advanced semiconductor solutions, is entering the automotive radar market with the introduction of a 4×4-channel, 76-81GHz transceiver designed to meet the demanding requirements of ADAS (advanced driver assistance systems) and Level 3 and higher autonomous driving applications. Leveraging automotive expertise accumulated through years of global customer engagements, 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 cooperation with Steradian Semiconductors Private Limited, which Renesas acquired earlier this year, the RAA270205 is featured in a Renesas product showcase at electronica, Munich, Germany, November 15-18, 2022. 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. 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 best-in-class accuracy with up to 5GHz of bandwidth, and a 112.5MSPS ADC (analog-to-digital converter) sampling rate that is nearly three times faster than competing devices. Power consumption of 1.2W is 50 percent lower than comparable transceivers and it delivers a noise figure of 9dB, which is 3dB less than other radar transceivers. Its superior chirp rate of up to 300MHz/µs 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 Electronics Corporation, a premier supplier of advanced semiconductor solutions, is expanding its low-power WAN product line as part of its strategy to deliver connectivity devices used for smart cities, smart homes, medical devices and industrial applications. The new RYZ024A supports Cat-M1 and NB-IoT (Narrowband Internet of Things) internet connectivity without the need for a gateway and consumes just 1µA (microamp) while in power savings mode, significantly less than competing products. The RYZ024A supports extended discontinuous reception (eDRX) and has an extended voltage range from 2.2V to 5.5V which makes it ideal for battery-powered applications. Renesas announced the details of the new product at electronica, Munich, Germany, November 15-18, 2022.

Similar to its predecessor, the RYZ014A module, the RYZ024A offers seamless Cat-M1 wireless connection capability, but the new module adds the option to integrate NB-IoT. While Cat-M1 and NB-IoT are both Low Power Wide Area Network (LPWAN) technologies, NB-IoT uses only a portion of the available spectrum, making it more power efficient and therefore extending the operational life of battery-powered systems. NB-IoT also offers excellent coverage depth, including underground and in enclosed spaces. The module provides two power amplifier output levels: 20dBm (decibel-milliwatts) and 23dBm, ensuring coverage at the cellular network’s edge as well as deep indoor environments.

The RYZ024A is being developed in collaboration with Sequans, a leader in cellular IoT technology, and will be fully tested and certified to work with all major radio frequency regulatory specifications defined by organizations such as the Global Certification Forum (GFC) and the PCS Type Certification Review Board (PTCRB). The certification ensures compliance with complex RF regulatory and carrier-specific requirements so that engineers can immediately start building IoT systems for leading carriers in North America, Asia Pacific and Europe.

“Cellular LTE-M and NB-IoT categories are now the de-facto wireless standards for connecting low-power IoT devices with global network coverage,” said Georges Karam, CEO of Sequans. “Renesas’ second-generation wireless module based on our Monarch 2 platform offers a certified hardware and software combination with all of the advanced features needed to accelerate the implementation of wireless IoT systems around the world.”

Renesas will provide all the tools and software that engineers need to design IoT-ready, power sensitive systems based on the RYZ024A, including an evaluation kit, a software stack and RF certifications. Compared to conventional chipset-based designs, designing in the RYZ024A module will reduce the PCB size by 60 percent and cut development time by up to 90 percent, since the product offers full hardware and software support to integrate the RA or RX family of MCUs.

“Renesas has been aggressively expanding its connectivity portfolio with strategic partnerships and acquisitions for the past five years,” said Roger Wendelken, Senior Vice President in Renesas’ IoT and Infrastructure Business Unit. “The RYZ024A is a great example of our expansive connectivity solution offerings that complement our broad range of embedded microcontrollers and microprocessors to deliver performance, scalability and exceptional reliability.”

For example, it can be used to detect the presence and location of people in a room to redirect and optimize air-conditioning flows, saving on energy costs. Another example could be intrusion detection to secured facilities or connected cameras with motion sensing to activate the camera. The combined connectivity and sensing chip is currently scheduled for production in the next 18 months.

Wi-Fi 7, also known as Extremely High Throughput (EHT), will deliver significantly faster throughput by employing faster modulations and double the bandwidth. In the 6GHz band, Wi-Fi 7 would more than the double the maximum speed and will increase speeds in the 2.4GHz and 5GHz band by as much as 30 percent. More importantly, some prominent features of Wi-Fi 7 will improve network reliability, latency and user experience. For example, by delivering Multi Link Operation, devices would monitor multiple links across different bands and provide consolidated operation to optimize interference and retransmission avoidance. Users will benefit from more reliable networks and from lower and more predictable latency. Wi-Fi 7 is expected to launch in 2024 with early adoption in mobile phones, computers and networking devices. Broader adoption in IoT, industrial and consumer multimedia applications will follow.

Renesas’ Wi-Fi 7 offerings will include solutions for home networking, IoT, industrial and consumer multimedia devices.

“Many recent developments are converging to create an era of market revolution in residential and enterprise Wi-Fi,” says Andrew Spivey, Industry Analyst at ABI Research. “Driven by a desire to take advantage of the new 6 GHz spectrum, which offers the prospect of greatly improved throughput and latency as well as reduced congestion on legacy bands, penetration of 6 GHz into Wi-Fi devices will rise rapidly in coming years. Meanwhile, the flourishing of new forms of Wi-Fi value added services such as Wi-Fi motion detection and the adoption of Wi-Fi 7 access points will accelerate following the protocols standardization in 2024, and just two years later, most 6 GHz enabled access point shipments will be supporting Wi-Fi 7.”

“Renesas can now offer truly differentiated Wi-Fi solutions that provide maximum performance, security and cost-competitiveness in combination with our industry-leading MCU and MPU offerings,” said Gilad Rozen, Celeno CEO and Vice President of Wi-Fi Connectivity in Renesas’ IoT and Infrastructure Business Unit. “Our customers are pleased with the direction we have chosen, and we are confident that we will deliver the right products for the market at the right time.”
