ST232ABDR Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the ST232ABDR?
  The maximum cable length supported by the ST232ABDR is 50 feet (15.24 meters) at a data rate of 115.2 kbps, but it can be extended up to 100 feet (30.48 meters) at a lower data rate.
• How do I handle the flow control in the ST232ABDR?
  The ST232ABDR supports hardware flow control using RTS/CTS signals. You can also use software flow control using XON/XOFF characters. The device also has a built-in FIFO buffer to handle data transmission and reception.
• What is the power consumption of the ST232ABDR?
  The power consumption of the ST232ABDR is typically 5mA at 3.3V supply voltage, but it can vary depending on the operating frequency and data transmission rate.
• Is the ST232ABDR compatible with 5V systems?
  Yes, the ST232ABDR is 5V tolerant, but it operates at a maximum voltage of 3.6V. You can use a voltage regulator to step down the 5V supply to 3.3V for the device.
• How do I configure the baud rate of the ST232ABDR?
  The baud rate of the ST232ABDR can be configured using the crystal oscillator frequency and the divisor values. You can use the STMicroelectronics' serial communication software development kit (SDK) to configure the baud rate.
