Calterah Andes chip products are the industry's first mmWave radar SoCs based on the 22 nm CMOS technology. Andes SoCs boasts a unique architecture of a multi-core CPU, a DSP, and an RSP, offering stronger computing power and better RF performance compared to the 40 nm chip. Its Flex-Cascading^® functionality empowers the powerful automotive imaging radar system. The Andes SoCs offer the most leading-edge designs of computing power, RF module, cascading functionality, debugging system, cybersecurity, etc.
(1) Computing power: The quad-core CPU provides over 2000 DMIPS of computing power. The computing speed of the DSP core is three times that of its competing products. Calterah's proprietary RSP achieves ultra-fast processing of radar signals.
(2) RF module: The Andes SoCs boast a 7-bit phase shifter based on transmission line design, supporting functions such as flexible generation of various waveforms and precise digital compensation unit.
(3) Cascading functionality: The Andes product offers Chip-to-Chip (C2C) interfaces for data exchange, enabling the Flex-Cascading^® function to connect multiple chips, simplifying software design and operation. The C2C interfaces also support other functions such as distributed signal processing.
(4) Debugging system: The debugging system of Andes SoCs provides various interfaces such as JTAG and Aurora, multiple data channels, and analysis modules.
(5) Cybersecurity: The Andes SoCs use the “Security Island" design, supporting hardware acceleration for all encryption and decryption algorithms.
With Calterah’s innovative Flex-Cascading technology, Andes SoCs can achieve high-performance radar systems, facilitating a smooth transition from high-performance ADAS radar to autonomous driving (AD) radar. Depending on the actual requirements of radar systems, different numbers of Andes SoCs can be cascaded to achieve the highest cost-efficiency for radar with the greatest flexibility.
In 2024, Calterah revealed its latest innovative products and technologies, including the 2-chip cascading imaging radar solution using Andes SoCs, which redefines the development paradigm of imaging radar, the Kunlun auto-grade mmWave radar SoC platform, which expands the scope of vehicle perception, and the cutting-edge mmWave package technology—Radiator on Package (ROP^®). Calterah has offered technologies and products for all three major market segments of mmWave radar: ADAS radar, imaging radar, and emerging short-range radar. To cater to the diverse needs of these segments, Calterah provides a comprehensive product portfolio, including chips based on the Alps platform (with SoC families such as Alps, Rhine, Alps-Mini, and Alps-Pro), the Andes SoC family based on the Andes platform, etc. The Alps platform covers traditional and emerging radar applications such as forward-looking radar, corner radar, in-cabin radar, and door radar, while the Andes SoCs are applied to higher-performance radar, supporting the cascading of multiple chips to achieve 4D premium radar and imaging radar functions. Calterah has a customer-centric sales team and a professional technical support team, providing support to customers throughout the entire project lifecycle, from initial project introduction to mass production. Sales and technical support services are available in Shanghai, Suzhou, Hangzhou, Shenzhen, and Munich. The rapid development of intelligent vehicles leads to an increasing demand for auto-grade chips. As one of the most important suppliers in the domestic mmWave radar chip market, Calterah has swiftly expanded its business scale and increased the number of its employees. As of now, Calterah’s accumulative chip shipments have exceeded 8.5 million units, and counting. And its share in the China market is expected to reach 20% this year.
