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.

Wireless and wired connectivity within a vehicle, including V2X (vehicle to everything), secure car access, radio and Wi-Fi technologies, are integrated into a single connectivity domain controller.

The OrangeBox development platform simplifies access to integrated connectivity technologies through one software platform to reduce costs and streamline development, said NXP.

OrangeBox integrates a variety of NXP wireless technologies, from broadcast radio, Wi-Fi 6 and Bluetooth, to secure car access with Ultra-Wideband (UWB) and Bluetooth Low Energy (BLE) and 802.11p-based V2X. It is a single, security- enhanced, modular development platform that provides a unified interface between the vehicle’s gateway and its wired and wireless technologies for V2X communications.

OrangeBox unifies current and emerging external wireless interfaces, for infotainment to advanced safety features, for example, into a single, security-enhanced connectivity domain controller, which connects to the secure vehicle gateway through NXP high-speed Ethernet. It is designed to reduce effort for development teams, while optimising the movement of data across multiple communication interfaces. Importantly, it also enables consistent security protection to be applied to all data traffic entering the car and eases the deployment of V2X and cloud applications such as over-the-air (OTA) updates for software-defined vehicles.

Designed as a modular platform, OEMs and Tier 1s can use OrangeBox to adapt to regional requirements for cellular connectivity and V2X and enable in-field updates to keep up with changing technologies, said NXP.

“By consolidating automotive wireless technologies into a centralised domain controller with a high- speed connection to the vehicle gateway, we are creating a single pathway for the vehicle to seamlessly connect to the rest of the world,” said Dan Loop, vice president and general manager for automotive edge processing, NXP. “Not only can this help to reduce costs and streamline development, it addresses a critical piece of the puzzle for data-enriched vehicles that require centralised, secure connectivity,” he added.

The central processor of the OrangeBox is an i.MX 8XLite applications processor running a unified Linux-based software platform to manage the automotive wireless connectivity. There is an NXP Gbit Ethernet connection to the central vehicle gateway to allow other automotive systems to access integrated wireless connectivity.

The OrangeBox automotive development platform is expected to be available in the first half of 2023.
