Under the background of accelerating the replacement of domestic chips,the domestic semiconductor market is facing new opportunities and challenges.As an important solution for wireless serial communication,CH9140,a low-power Bluetooth-to-serial communication chip,is gradually becoming the preferred device in industrial and consumer electronics industries with its stable and reliable performance.The Bluetooth-to-serial chip represented by Yingshang was developed by Qinheng Microelectronics,supported by Bluetooth BLE 4.2 protocol,which can realize efficient data exchange between serial devices and Bluetooth modules and successfully break through the distance limit of wired connection.

 

 

　　CH9140 Bluetooth-to-serial chip is compatible with master-slave integration and slave mode,and has high system expansibility.Its built-in virtual serial port driver allows the computer system to directly identify the Bluetooth interface as an ordinary serial port,which is compatible with most serial port debugging tools and the original serial port program.Wireless communication can be realized without additional development,which ensures that the module can work safely and reliably in various complex application scenarios and greatly shortens the integrated development cycle.CH9140 Bluetooth-to-serial chip not only realizes two-way data transmission between Bluetooth and serial port,but also integrates common peripheral interfaces such as IO control and ADC acquisition to help traditional serial port equipment quickly upgrade to Bluetooth intelligent node.

 

 

　　CH9140 series Bluetooth serial chips are mainly used in smart wearable devices,smart homes,industrial Internet,data collection,vehicle systems,security monitoring devices and many other fields,providing high-quality underlying hardware support for wireless devices,remote monitoring systems and intelligent control systems.Whether it is used for product prototype development or mass production,Bluetooth-to-serial chip can help developers to quickly expand the Bluetooth function of serial devices and promote the evolution of terminal connection to wireless and intelligent systems.
