Silicon Internet of Things Technology Co., Ltd (SIT) has "extremely low noise sensor signal processing technology" and "high precision sigma delta technology". It takes "core" to make special chips for the national demand as its own duty, and makes related chip technology research around the Internet of things such as smart grid. It has successfully developed a new generation of intelligent lightning resistant RS485 chip, can interface chip, RTC chip and OFDM communication chip Chip, MEMS signal processing chip, etc. Around these core technologies, the company has applied for more than ten national intellectual property rights and initially established its own patent protection system. Core power has 7 invention patents, 7 integrated circuit layout protection and 10 invention patents.
