S80 Image

The S80 from Uhnder is a 4D Digital Imaging Radar-on-Chip (RoC) that operates from 76 to 81 GHz. It has a phase-modulated continuous-wave (PMCW), multiple-input multiple-output (MIMO) radar architecture that is capable of processing up to 192 virtual channels. This chip supports 12 transmit antenna channels (Tx), 16 receive antenna channels (Rx) and can be cascaded up to 4 levels. It is Digital Code Modulation (DCM) certified for use in automotive safety applications, such as automatic emergency braking (AEB), lane keeps assist, adaptive cruise control, blind-spot detection, as well as automated driving functions, including autonomous vehicles.

The S80’s DCM minimizes mutual interference from neighbouring radars and provides high contrast resolution (HCR) delivering maximum discrimination as well as high-confidence detection of independent targets, including vulnerable road users (VRUs), such as pedestrians and cyclists, in long-(LRR), mid-(MRR), and short-range radar (SRR) applications. It is fully software-defined, has built-in processors to run algorithms on-chip, and can also enable optimization with deep learning neural networks and artificial intelligence (AI) found in the most advanced automated perception systems.

The S80 delivers a combined output power of 22 dBm, has a range resolution of 7.5 cm, and has a noise figure of 10 dB. It provides Rx channel isolation of more than 25 dB and Tx to Rx channel isolation of more than 50 dB. This AEC-Q104 qualified chip is available in an eWLB package that measures 12.80 x 8.21 mm with 100/1000 Ethernet, CAN-FD, I2C, QSPI, and GPIO interfaces.
