HOW DOES IT WORK?
USB UART ISO Click is based on the ISOUSB111, a full/low-speed isolated USB repeater from Texas Instruments. It is a galvanically isolated USB 2.0 repeater that supports automatic speed connection detection, reflection of pull-ups/pull-downs, and link power management. The repeater isolates D+ and D- USB bus lines and supports automatic role reversal. This means that, after disconnection, if a new connection is detected on the upstream-facing port, then the upstream and downstream port definitions are reversed. This device uses a silicon dioxide insulation barrier with a withstand voltage of up to 5000VRMS and a working voltage of 1500VRMS, thus protecting from high voltages and preventing noise currents from the bus entering the local ground.
This USB repeater also comes with a pair of unpopulated headers for testing purposes for both sides of the isolation barrier. Both headers contain a GND (for both sides), a powered-up indicator pin (V1OK or V2OK), and power supply pins for both sides.
USB UART ISO Click is equipped with a USB type C connector, which can connect a USB device to a host MCU over the UART bridge and a USB isolated repeater. The FT232R is a well-known UART bridge chip on which the entire USB protocol is handled on the chip. There is driver support for all common operating systems. The UART chip comes with a pair of UART RX and TX LEDs to visually present UART data flow.
USB UART ISO Click uses a standard UART interface to establish communication of the connected USB device with the host MCU over the UART bridge and an isolated USB repeater. In addition, the UART flow control pins RTS and CTS are available. Additionally, there is an SLP pin for Sleep mode control and a PWR pin as a power enable pin.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VIO SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
