Calterah was invited to the forum Homegrown Chips ‧ Future of Intelligent Driving on the development of chips for intelligent driving co-organized by Leapmotor and 21st Century Business Herald on Oct. 27. At the forum, Leapmotor launched China’s first automotive-grade AI chip with domestic IPs from tip to toe for intelligent driving, the Lingxin 01, which will be used in Leapmotor’s first premium pure electricSUV C11. As a partner providing essential radar sensor chips for Leapmotor C11 intelligent driving system, Calterah attended the launch conference. (photos by 21 Century Business Herald) Launch of Leapmotor Lingxin 01 Calterah as a leading player in developing and designing CMOS mmWave radar chips launched its 2nd generation of automotive-grade CMOS 77-GHz mmWave radar SoC, the Alp family last year. Now, a total of 5 chips from the Alps family are used for front and corner radar sensors in C11. The features of strong performance, user friendliness and energy efficiency make Alps ideal for radar sensors demanded by Leapmotor’s high-performance electric vehicles, which reduces time and cost in product development and thus accelerates the transition from concepts to real products.   Calterah Alps in C11 intelligent driving system  At the roundtable with a theme of Trailblazing……

On Oct. 28, 2020, awarding ceremony of Gasgoo Awards 2020 organized by Gasgoo.com was held in Shanghai. With expert review and millions of votes in 90 days, the Awards including Influential Figure 2020 had finally come to a completion. To award his dedication to R&D, branding and quality, and outstanding contribution to the automotive industry and society at large, Dr Chen Jiashu, CEO of Calterah Semiconductor, was honored with Influential Figure 2020 of Gasgoo Awards. Dr Chen earned his PhD degree in Electric Engineering from University of California, Berkeley. As a PhD candidate, Mr Chen worked in Berkeley Wireless Research Center and did some leading research in CMOS RF and mmWave integrated circuits, contributing significantly to the design theory of mmWave circuits, architecture of phased-array transceivers, and power amplifier design. In 2014, Dr Chen came back to China and established Calterah Semiconductor. Under his leadership, Calterah in 2017 mass-produced world’s first CMOS 77/79-GHz mmWave RF front-end radar-on-chip for automotive use, and soon took the lead to break into the automotive original market. In 2019, Calterah rolled out radar SoC with integrated baseband, bringing revolutionary progress to mmWave radar sensor development. “Our mission is to become the world’s best in our……

On August 27, at the third China IC Unicorn Forum of the World Semiconductor Conference 2020, the results of China IC Unicorns 2019 were announced, and an award ceremony followed. Calterah Semiconductor was awarded the Fengyan Innovative Enterprise and IC Unicorn 2019. Group photo of the presenter and representatives from awarded enterprisesCalterah: the third one from the left The selection work of China IC Unicorns 2019 kicked off in May this year. For more than two months, a total of over 200 recommendations either from enterprises themselves or from industrial organizations were reviewed and 55 shortlisted enterprises stood out. Finally, 24 enterprises including Calterah were awarded the honor.  With the mission to be the world’s best mmWave radar chip and solution provider, Calterah will continue to provide timely, comprehensive, and efficient support and services to users all over the world, making mmWave technology accessible to millions of families.

Capable of detecting subtleties, mmWave radar can sense fine motions of the objects, which enables itself to detect vital signs such as respiration and heartbeat in a relatively long range and therefore to obtain real-time respiration rates and heart rates without body contact. Breathing causes micromotions in the chest and abdomen, which can be sensed by mmWave radar and translated into breath rates information. This also applies to heart rate monitoring. Respiration signs detected by mmWave radar Heartbeat signs detected by mmWave radar Realization of core functions The Calterah AiP (Antenna in Package) chip integrates a radar baseband processing unit (RBPU), which enables users to achieve the pre-processing of respiration and heartbeat signs by configuring registers in the real application. The integrated 300-MHz ARC® 32-digit MPU, 640-KB RAM and 1-MB expandable memory of AiP chips can further meet requirements for the processing of more diverse and personalized algorithms. A typical process for the processing of respiration and heartbeat signs The RBPU of Calterah AiP chips can efficiently complete the first 4 procedures above in real time while the last 3 can be done with the help of the ARC processor. Also, users can further harness the potential of Doppler FFT……

Market demand and challenges of USRR Auto driving and advanced driving assistance systems generally consist of sensing, controlling and actuation. Sensing relies on sensors of all sorts such as mmWave radar, cameras, laser radar and ultra sound wave. Front long-range radar and corner radar are applications of mmWave radar that we are familiar with. They are employed in highway and urban road driving scenarios to realize functions like ACC, AEB, BSD and LCA. The Alps family of SoC chips that Calterah brought about in 2019 well facilitates the development and realization of these two kinds of radar. The following scenarios are no strangers to us: In peak hours, roads are combusted with vehicles. Positioning will be much harder when there is an obstacle above the vehicle, an overpass for instance. In a big parking lot, there is trouble finding space and parking a car. The absence of separation of pedestrians and vehicle leads to a greater chance of traffic accidents. (Pictures from online sources) What these scenarios have in common is complex road conditions, slow driving speed, and necessity for drivers to have a good sense of surrounding situations. However, existing sensors are barely satisfactory in short-range coverage. Ultra sound……

Recently, TÜV Rheinland issued ISO 26262 Functional Safety Management Certificate to Calterah Semiconductor, making Calterah one of the two fabless design houses in China semiconductor industry that has achieved this certification. Covering the functional safety requirement planning, design, implementation, integration, verification, confirmation measures and configuration, ISO 26262 series of automotive functional safety standards is one of the market thresholds for E/E part suppliers to enter the automotive industry, with the aim of minimizing the risks from automotive E/E system failures through comprehensive development processes. ISO 26262 series of standards provides a risk-based approach to determine automotive safety integrity levels (ASILs). There are four ASILs defined, ASIL A, B, C and D, with D representing the highest level and A the lowest level. A higher ASIL level means more stringent requirements on system safety, hardware diagnostic coverage and development processes, which also puts a higher demand on technology. ▲Calterah Obtained ISO 26262 Functional Safety Management Certificate Based on ISO 26262:2018, Calterah Semiconductor has established a complete set of functional safety product development process, which supports the development of IC products with up to ASIL D level. As safety is the basic requirement of intelligent drive, Calterah has always put a priority……
