1. The chip on the USB serial port is used to realize the conversion and communication between the USB and the serial port. 2. USB is a universal digital interface standard, while serial port is a traditional communication interface.
USB Serial port chip is used to convert the digital signal of the USB interface into the analog signal of the serial port interface for serial communication with other devices.
It can convert the high-speed, bidirectional, multi-wire complex communication protocol of the USB interface into a simple, low-speed, one-way communication protocol of the serial interface.
3. The application of USB serial chip is very wide.
It can be used to connect computers with external devices, such as printers, scanners, cameras, etc., to achieve data transmission and control.
At the same time, it can also be used in embedded systems, embedded devices and computers to communicate, to achieve data acquisition, control and monitoring.
The appearance of USB serial port chip greatly facilitates the communication and data exchange between devices.
The function of the chip is to convert the USB protocol into the serial protocol.
