3.9. USB Interface

EC200T series provides one integrated Universal Serial Bus (USB) interface which complies with the
USB 2.0 specification and supports full-speed (12 Mbps) and high-speed (480 Mbps) modes. The USB
interface can only serves as a slave device and is used for AT command communication, data
transmission, software debugging and firmware upgrade. The following table shows the pin definition of
USB interface.
