Shulou(Shulou.com)11/24 Report--

On September 5, the 2023 German International Automotive and Smart Travel Expo (IAA MOBILITY) kicked off in Munich. Gartland, as a leader in millimeter wave radar chips, showcased the industry's most comprehensive portfolio of automotive specification class millimeter wave radar chips and demonstrated the latest pre-radar and high-performance angle radar solutions based on Alps-Pro chips. Gatland's new generation millimeter wave radar SoC product Andes, which is used to realize 4D high-end radar and imaging radar, has attracted wide attention in the booth and represents the current cutting-edge millimeter wave radar technology.

According to the latest disclosure, so far, more than 6 million Gatland chips have been shipped and more than 150 models have been successfully located. in the past few years, the Gatland chip shipment rate has maintained an annual growth rate of 100%. And has made breakthroughs in the UK, the Middle East and South Asia. "Europe is one of the most important automotive markets," Gartland COO Lu Yuzhao said in an interview with IAA. "We will continue to increase our investment in the European market and establish closer cooperation with European customers to apply our unique technology to imaging radar, high-performance ADAS radar and emerging applications."

The most complete gauge-class millimeter wave radar chip combination in Gartland industry

Gatland leads the industry in millimeter wave radar SoC chips with high integration and cost advantages, and has the industry's best PPA (Performance, Power, Area power consumption, performance, area). The Gatland chips unveiled in IAA MOBILITY include 76-81 GHz and 60-64 GHz millimeter wave radar SoC chips based on next-generation product platform Andes and second-generation product platform Alps, which are widely used in Advanced Autopilot system (ADAS) and L2 + self-driving fields, including imaging radar, front radar, angle radar, side radar, cabin radar, tailgate radar and automatic door anti-collision radar.

Note: Alps, Rhine, Alps-Mini and Alps-Pro series are all developed based on the second generation SoC product platform of Gatland.

The Andes (CAL77C844-AF) chip that attracted much attention at the exhibition is Gatland's new generation millimeter wave radar SoC product, which represents the current cutting-edge millimeter wave radar technology, which can achieve 4D high-end radar and imaging radar functions. The Andes chip adopts the unique architecture of multi-core CPU + digital signal processor (DSP) + radar signal processor (RSP). CPU uses a four-core Xtensa ®LX7 processor, and the DSP computing speed is 3 to 10 times faster than that of competitive products. The self-developed RSP helps to realize the ultra-fast processing of radar signals. The RF front-end supports flexible generation of various waveforms to meet the needs of different use scenarios and waveforms. The flexible cascade (Flex-Cascading) function supports cascading of any number of chips and can realize cascaded 4D radars of different sizes. The chip also has rich and convenient debugging functions, can simplify the development process, its network security module, using "safety island" design and support a variety of encryption and decryption algorithms, can adapt to the growing security requirements. The Andes 4D imaging radar scheme also eliminates the additional MCU chips, which is superior to the cascaded 4D radar scheme with MMIC chips in terms of performance-to-price ratio. Because of its superior performance and high performance-to-price ratio, Andes chip has become the best choice for the development of multi-chip cascaded 4D imaging radar and has been widely concerned by many international exhibitors and potential customers.

At the exhibition site, Gatland demonstrated the latest pre-radar scheme and high-performance angle radar scheme based on Alps-Pro chip. The Gartland Alps-Pro chip (CAL77S344-AE), released at the end of 2022, is a new 4T4R 77 GHz millimeter wave radar SoC chip based on the Gartland Alps platform. The detection range of the angle radar and the front radar equipped with Alps-Pro can reach 180m and 240m respectively, the horizontal angle accuracy is ±0.1° and the resolution is 4° and 2.8° respectively, which perfectly meets the requirements of L2 + autopilot.

The Alps AiP and Rhine AiP chips on display are also the world's first successful mass production of package integrated antenna on chip (Antenna-in-Package, AiP) SoC products. Thanks to AiP technology, radar modules can avoid antenna design and do not need to use high-frequency plates, thus shortening the radar development and production cycle, further reducing costs, and achieving a very miniaturized module size, highly adapted to the needs of ultra-short-range radar inside and outside the car body, such as side radar, tailgate radar and other emerging applications.

Gartland, global leader in CMOS millimeter wave radar chips

Gatland has been ploughing CMOS millimeter wave radar chips for many years and has produced millions of car gauge chips. According to the latest disclosure of Gatland COO in an interview with IAA a few days ago, "so far, Gatland has shipped more than 6 million car gauge chips and successfully designated more than 150 models." The mass production capacity of this million-level automotive specification-level chip depends not only on reliable chip R & D and design, but more importantly, Gatland has established a series of automotive software and hardware research and development systems and chip production quality control processes that meet international standards:

Adhere to the goal of "zero defect" and embed a variety of management and control methods into the whole product process.

Management processes and products have obtained ISO 26262 functional safety certification

Software development into ASPICE management, and through professional certification bodies and international well-known Tier-1 evaluation

Become the first chip company in the domestic semiconductor industry to obtain ISO / SAE 21434 automotive network security certification.

At present, millimeter wave radar sensor has become the key perception technology of autopilot. Gatland's advanced millimeter wave radar technology is gaining more recognition and application around the world. Gatland is also actively exploring the global market, deepening cooperation with international well-known cars Tier-1 and OEM, and working together to create more competitive millimeter wave radar products and programs to help achieve a safer and smarter driving experience.
