Working Principles

The CY7C65210-24LTXI works by converting USB data packets into UART-compatible signals and vice versa. It utilizes an internal USB controller to handle USB communication and a UART controller to manage UART communication. The bridge controller acts as an intermediary, translating the data between the two interfaces.

When a USB host device sends data, the CY7C65210-24LTXI receives it through the USB interface, converts it into UART format, and transmits it to the UART-based peripheral device. Similarly, data from the peripheral device is received through the UART interface, converted into USB format, and transmitted to the USB host device.
