What is a USB bridge and how does it work?
A USB bridge is a type of integrated circuit that enables communication between two or more devices with different interfaces, such as USB, UART, SPI, or I2C. It acts as a protocol converter, allowing devices with different communication protocols to exchange data seamlessly. The USB bridge chip is typically connected to a USB host, such as a computer or a microcontroller, and provides a bridge to other devices or peripherals that use different interfaces. This enables the host device to communicate with the peripherals as if they were directly connected to the host’s USB port.
The USB bridge works by converting the data and control signals from one interface to another, allowing devices with different communication protocols to interact with each other. For example, a USB-to-UART bridge can convert USB signals to UART signals, enabling a computer to communicate with a device that only has a UART interface. The bridge chip handles the protocol conversion, data formatting, and flow control, ensuring that data is transmitted reliably and efficiently between the devices. By providing a bridge between different interfaces, the USB bridge enables the connection of a wide range of devices and peripherals to a USB host, expanding the possibilities for device connectivity and communication.
