Silicon Internet of Things Technology Co., Ltd （SIT）was founded in October 2012 in Xiangtan National High-tech Zone by returned overseas students. It is a high-tech enterprise specializing in mixed-signal integrated circuit design. Since its establishment, the company has grown rapidly upholding the corporate philosophy of “taking technology as the driving force for development and innovation as the foundation”. With the development of the company’s business, Jiangsu Sit Electronic Technology Co., Ltd. was established in August 2014. ISO9001 international quality system certification, EU CE certification. The company was rated as "National High-tech Enterprise", "Jiangsu Private Technology Enterprise", "Xiangtan High-tech Zone Enterprise Technology Center" by the Ministry of Science and Technology and other national provinces and cities, and has undertaken the "National Study Abroad Fund" and "Hunan Provincial Internet of Things Fund" There are 9 key national, provincial and municipal scientific research projects. The company has gathered a group of passionate, diligent, innovative and outstanding engineers in the field of sensor signal processing chip design at home and abroad, and a management team with international operation experience. The company’s employees have successively won the Hunan Province Hundred Talents Program, the Hunan Young Talents, and the Jinshan Young Talents, Jiangsu Double Entrepreneurship Plan, Six Talent Peaks in Jiangsu Province, Zhenjiang City Young and Middle-aged Experts with Outstanding Contributions, Zhenjiang 331 Project, Jurong Fudi Talents and other talent programs.

The company takes the "core" to make special chips as its mission to meet national needs, and conducts related chip technology research around smart grids and other Internet of Things, and successfully develops a new generation of intelligent anti-lightning 5V/3.3V full-duplex/half-duplex RS485 bus chips, 5V/3.3V RS232 interface chip, 5V/3.3V CAN bus chip, RTC chip, OFDM communication chip, MEMS signal processing chip, etc. Around these core technologies, the company has applied for more than a dozen national intellectual property rights and initially established its own patent protection system. The lightning-resistant RS485 chip product was rated as the "Eleventh (2016) China Semiconductor Innovative Product", the vehicle CAN transceiver chip won the 2019 China Core Excellent Product and Technology, and the core technology won the third prize of Xiangtan Science and Technology Progress Award.

At the same time, the company adopts a one-stop business model based on customer needs, tailor-made to meet customer specific needs and provide customized design services. Covers ASIC for MEMS servo signal processing, ASIC for optical sensor signal processing (infrared, visible light, etc.), various analog circuits (ADC (Sigma-Delta/SAR/Flash/Pipeline, etc.), DAC, PGA, PLL, BGAP, LDO, etc.) ) And back-end design and other IP design services or chip customization, customers covering Beijing, Shanghai, Shenzhen and Guangzhou, etc., have completed more than ten technical design services, all of which were successful and mass-produced at one time.

The company's product quality and services have been well received by customers. Based on the mission of "doing the best to make special chips", Sit will continue to innovate and provide customers with cost-effective products and services.
