Jiwei Network News, on December 17, the first Dishui Lake China RISC-V Industry Forum was held in Shanghai Lingang. At the meeting, Wang Zhenshan, vice president of Lingsi Microelectronics (Xiamen) Co., Ltd., introduced the company's vehicle-grade wireless MCU products.
Lingsi Microelectronics (Xiamen) Co., Ltd. is a chip design company focusing on the field of high-performance, high-reliability wireless microcontrollers (Wireless-MCU), and with BLE+MCU connection technology and high reliability as the center, long-term planning in high reliability, ultra-low power consumption, high performance and ecological community construction to establish core competitiveness. The company is good at industrial and vehicle specification level high reliability design, high performance and low power consumption analog design, high-speed SerDes design, dedicated hardware acceleration module, algorithm design and ecological scheme construction.
Founded in 2019, the company is a high-tech chip research and development enterprise supported by Xiamen. Headquartered in Xiamen, it has R&D centers and branches in Shanghai and Shenzhen. Now it has a R & D team of more than 50 people, the core team members have rich experience in SOC design, radio frequency, communication algorithms, software solutions, processes and quality. Ling Siwei has completed a round of nearly 100 million yuan of financing in 2021, and the investors include Kai Venture Capital, Huatian Technology, Changfu Capital and other institutions.
Wang Zhenshan took the Ultium wireless battery management system as an example and pointed out that the combination of wireless connection technology and various control systems instead of wired connection is the future trend, and its signal transmission harness volume will be reduced by 90%, the battery weight will be reduced by about 25%, and the temperature difference will be controlled within 1%, which will bring great improvement to the vehicle endurance.
Wang Zhenshan introduced that the LE503x series products are one of the vehicle-grade wireless MCU series products of Lingsiwei based on RISC-V architecture and BLE5.0/1 specification, which is a BLE MCU product with extremely low power consumption, and its main features are as follows:
I. Powerful product features: can be applied to a variety of low-power communication application scenarios;
II.. High RF sensitivity: reach 113dBm@1Mbps, 120dBm@125Kbps, leading performance in the world;
III.. Strong reliability: wide environmental adaptation range -25~125 degrees, ESD >8KV;
IV..IO configuration flexible: all interface GPIO interfaces can be flexibly configured according to needs, and only 3 peripheral circuit devices are required;
V: Rich peripherals: Integration includes 24bit AD, LCD driver, TP, USB and other functions.
Wang Zhenshan said that Lingsi micro vehicle specification MCU is mainly used in body control, instant communication, in-vehicle entertainment, the current project cooperation with Xiaomi is steadily underway, and the cooperation project with vehicle manufacturers is being promoted.
Wang Zhenshan pointed out that whether it is open source or free features, RISC-V is a good choice for domestic chip autonomy, and it is also very tempting for chip companies. Ling Siwei's partner Pingtou Brother is relatively perfect in the RISC-V ecosystem and technical support, which is very helpful for the company's product design efficiency. Many companies in the industry have transplanted ARM's development experience to RISC-V, whether it is technical experimentability or market response needs, which shows that RISC-V has become a trend in the future and has a broad market space.
