The Chronos chip is the foundation of the company’s DF architecture and is designed to enable more performant, power efficient, and compact digital lidar sensors that enable L2 to L5 automation in high-volume automotive series production vehicles. The Chronos chip harnesses the company’s proprietary digital lidar architecture and some of the latest advancements in semiconductor technology.

This design, says the company, allows its DF sensors to benefit from the same dramatic performance improvements that made the digital camera ubiquitous across industries. With superior logic and performance capabilities, the Chronos chip delivers improved memory, dynamic range, and detection accuracy.

The company says that it expects the Chronos chip to be the most powerful single-photon avalanche diode (SPAD)-based lidar chip produced to date.

“Unlike lidar technologies which require the complex integration of numerous off-the-shelf components, our proprietary and cutting-edge digital lidar technology produces simple and powerful sensors that automotive OEMs can trust to achieve new levels of safety and autonomy,” says Iain Levy, VP of Ouster Automotive. “Ouster Automotive’s Chronos chip represents the latest in SPAD technology, making our solid-state digital lidar sensors highly performant, reliable, power efficient, compact, and easily manufacturable.”

The Chronos chip is designed to meet ASIL-B automotive functional safety requirements according to ISO 26262 and AEC-Q100 automotive qualifications. The company says that it intends to tape-out the Chronos chip in late 2022, and to integrate the chips into the first sample units in 2023. It expects the DF series to be available for mass-market passenger vehicles starting production in 2025.
