On Dec. 24, China Auto Supply Chain Summit (CASCS) 2022 and the 7^th China Auto Parts Industry Awards (CAPIA, also known as the Lingxuan Awards) Ceremony were held in Wuhan, China. Calterah was honored with the Lingxuan Award for Excellent Forward-Looking ICs by virtue of its Andes family of mmWave radar SoC chips.

This honor came after last year’s recognition of the Lingxuan Award for Excellent Mass-Produced ICs for the Alps family of mmWave radar SoC chips. 

The products and technologies filed for this year’s Awards exceeded 200 cases and can be sorted into 10 categories, including intelligent driving and ICs. The jury for the Awards came from the purchasing and R&D departments of Chinese car makers and senior experts in the industry. After 4 rounds of deliberation and reviews, Calterah stood out for the advancement, applicability, and influence of its Andes mmWave radar SoC products, and won the Lingxuan Award for Excellent Forward-Looking ICs.  

Calterah’s Andes mmWave radar sensor SoC product family was officially launched at the Calterah Day 2022 event on Dec. 20. The next-generation SoC platform adopts the 22 nm process and integrates a multi-core CPU, a DSP, and an RSP. With extraordinary computation power, flexible cascading functionality, convenient debugging functions, and advanced security capability, Andes literally brings the most leading-edge mmWave technologies to the market.

One Andes SoC chip alone can be used for high-performance ADAS radar design and can replace the existing radar products on the market with a greater detection range, a larger FOV, and more accuracy. Two Andes chips cascaded together can be used for powerful L3+ auto driving radar, which can output rich point-cloud data while measuring the objects and modelling the environment. A cascaded system of three or four Andes chips can realize high-performance imaging radar functions, which will act as a main sensor of the auto driving system, achieving accurate measurement of objects, still and moving alike, within a rather wide area. As needed, cascaded systems of different numbers of SoCs can be realized for optimal flexibility and cost-efficiency.

For industry players down the supply chain, their engineers can reuse the toolchains and code and draw on the previous system design experience when using Andes for radar systems of different levels. In this case, the design cycle is cut short and companies are more capable of fulfilling various system-level requirements. When it comes to the mass production, stock management for different level of radar modules is made easier and costs for purchasing and storage are reduced because of the common use of Andes sensor chips. This is especially significant in light of the overall situation of unstable supply in the semiconductor market.

And this is also in line with the theme “Reaction” of this CASCS. Amid uncertainties, Calterah’s Andes family of mmWave radar sensor SoCs is poised to address the pressing demands for the supply chain development of the transforming automotive industry. In the meantime, the launch of Andes SoCs is expected to change the landscape of high-end radar chips where imported products dominate the market and thus facilitate the localization of premium auto radar modules.
