SN65C3221DB Frequently Asked Questions (FAQs)

  • The maximum cable length supported by the SN65C3221DB is dependent on the baud rate and the type of cable used. As a general guideline, the maximum cable length for a baud rate of 9600 is around 100 meters, while for a baud rate of 115200, it is around 10 meters.
  • The SN65C3221DB can be configured for half-duplex or full-duplex operation by connecting the RTS (Request to Send) and CTS (Clear to Send) pins accordingly. For half-duplex operation, connect RTS to CTS, and for full-duplex operation, connect RTS to a separate output and CTS to a separate input.
  • The power consumption of the SN65C3221DB depends on the operating mode and the supply voltage. In normal operation, the typical power consumption is around 10mA at 5V supply voltage. In shutdown mode, the power consumption is typically less than 1uA.
  • Yes, the SN65C3221DB can be used with a 3.3V supply voltage. However, the output voltage levels will be reduced accordingly, and the device may not be able to drive loads as effectively as it would with a 5V supply voltage.
  • The flow control pins (RTS and CTS) can be handled using a microcontroller's GPIO pins. The microcontroller can generate the RTS signal based on the transmit buffer status, and monitor the CTS signal to control the transmission of data.
