Hangzhou Vango Technologies, Inc.Hangzhou Vango Technologies, Inc. (abbr. Hangzhou Vango) established in 2006, a national high-tech enterprise aiming at developingspecific chips for energy loT in China. Hangzhou Vango insists self- innovation and dedicates to provide complete energy loT chips and solutions. After years of development, Hangzhou Vango has accumulated 60 patens in low- power high-precision analog circuit design, MCU/MPU Processor design, Metering and G3-PLC communication algorithms, SoC systematic design and high reliability design (Three -quarters of these patents are developing patents, including American development patents.) and more than 10 pieces of integrated circuit layout. In addition, Vango established Hangzhou Vango electric power loT chips high-tech enterpriseresearch and development center, and gradually formed three categories:MCU/SoC Communication chipsets Metrology AFE chips. According to the achievements of core technologies, Vango lots of research projects have won the 17th, 18th, 20th“China Patent Excellence Award, the 21st “China Patent Silver Awards”; and the third consecutive“China Semiconductor Innovative Products and Technologies Hangzhou Vango Technologies will continue to insist in the innovative empowerment, build in full-link product system, and overcometechnical difficulties to support product industrialization process and promote the high-quality development.
