The SAF85xx one-chip family combines NXP’s high performance radar sensing and processing technologies into a single device, offering tier ones and OEMs much greater flexibility in addressing short, medium and long-range radar applications to serve ever more challenging NCAP safety requirements.
These automotive radar SoCs comprise of high-performance radar transceivers integrated with multi-core radar processors which are built on NXP’s S32R radar compute platform. The SAF85xx offers twice the RF performance and accelerates radar signal processing by up to 40%, compared to previous generations.
The one-chip family enables 4D sensing for corner and front radar, serving critical safety ADAS applications, such as automated emergency braking, adaptive cruise control, blind-spot monitoring, cross-traffic alert and automated parking.
According to NXP, OEMs will benefit from the increased flexibility it offers in meeting the expanding NCAP safety requirements and the proliferation of radar sensors, which some analyst estimates project will range to up to five or more per car.
When combined with NXP’s power management and connectivity solutions, the flexibility of the system solution will make it possible to address a wide variety of OEM needs. Developers can take advantage of the S32R scalability as well as its software and hardware design reuse benefits.
“Our new radar one-chip family enables the reliable long-range detection of objects and separation of small objects next to larger ones, like a fast-moving motorcycle next to cars and trucks on a busy multi-lane highway,” said Torsten Lehmann, Executive Vice President, NXP Semiconductors. “Its small form factor allows our customers to build radar sensor modules that are up to 30 percent smaller, enabling global suppliers of ADAS systems, like DENSO, to expand the potential of radar safety through this powerful new technology.”
NXP’s 3rd Generation RFCMOS Radar Platform
- Built on the proven RFCMOS expertise of NXP, which was the first to ramp to high volume series production for automotive radar and has already shipped tens of millions of units;
- Highly integrated 77 GHz radar smart transceiver SoC contains four high-performance transmitters, four receivers, a multi-core radar processor with hardware accelerator, Gigabit Ethernet communication interface and memory;
- Targets the Automotive Safety Integrity Level B (ASIL B) requirements, according to the ISO 26262 functional safety standard and the automotive cybersecurity standard ISO/SAE 21434 to meet the requirements of the automotive industry for safety and security.
