5.6.3. Serial Ports

The ME310G1 module is provided with by 3 Asynchronous serial ports:

• Asynchronous Serial Port (USIF0)

• Asynchronous Serial Port (USIF1)*

• Auxiliary Serial Port

Several configurations can be designed for the serial port on the OEM hardware, but the

most common are:

• RS232 PC com port

• microcontroller UART @ 1.8V (Universal Asynchronous Receive Transmit)

• microcontroller UART @ 5V or other voltages different from 1.8V

Depending from the type of serial port on the OEM hardware a level translator circuit may

be needed to make the system work. On the ME310G1 the ports are CMOS 1.8.

NOTE:

*The USIF1 is currently NOT supported by ME310G1 firmware.
