One-chip radar

For safety-related ADAS applications

NXP announced the SAF85xx radar IC family with two CAN FD interfaces for use in next-generation driver assistant and autonomous driving systems. The ICs are already sampled to lead customers.

The 28-nm IC (integrated circuit) family combines NXP’s radar sensing and processing technologies on a single chip addressing short-, medium-, and long-range radar applications. SAF85xx integrates a 77-GHz radar transceiver SoC (system on chip) combining four transmitters, four receivers, a multi-core (Arm Cortex-A53, Arm Cortex-M7) radar processor with hardware accelerator, two CAN FD interfaces, Ethernet (up to 1-Gbit/s) interface, and memory. The IC family offers twice the RF (radio frequency) performance and accelerates radar signal processing by up to 40 %, compared to NXP’s previous generation.

The one-chip solution enables 4D sensing for corner and front radar, serving safety-related ADAS applications, such as automated emergency braking, adaptive cruise control, blind-spot monitoring, cross-traffic alert, and automated parking. The IC family serves the latest NCAP (European New Car Assessment Programme) safety requirements, informs NXP. It targets the ASIL B (automotive safety integrity level) requirements, according to ISO 26262 functional safety standard as well as the automotive cybersecurity standard ISO/SAE 21434 to meet the requirements of the automotive industry for safety and security.

Denso Corporation intends to leverage NXP’s latest radar technology to drive its next-generation ADAS platform development. Torsten Lehmann, Executive Vice President at NXP Semiconductors explained: "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. 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."
