ST232CN Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the ST232CN?
  The maximum cable length supported by the ST232CN is 100 meters (328 feet) at a data rate of 115.2 kbps. However, this length can be affected by factors such as cable quality, noise, and data rate.
• Can the ST232CN operate in harsh environments?
  Yes, the ST232CN is designed to operate in harsh environments, including industrial and automotive applications. It can withstand temperatures ranging from -40°C to 125°C and has built-in protection against electrostatic discharge (ESD) and electrical fast transients (EFT).
• How does the ST232CN handle data transmission errors?
  The ST232CN has built-in error detection and correction mechanisms, including parity checking, stop bit checking, and framing error detection. It also supports flow control and XON/XOFF protocol for reliable data transmission.
• Is the ST232CN compatible with other UART devices?
  Yes, the ST232CN is compatible with other UART devices that comply with the RS-232 standard. It can communicate with devices from other manufacturers, including PCs, microcontrollers, and other serial devices.
• What is the power consumption of the ST232CN?
  The power consumption of the ST232CN depends on the operating mode and data rate. In normal operation, the device consumes around 5 mA at 5 V supply voltage. In low-power mode, the current consumption can be as low as 50 μA.
