Question:Is there any way to judge whether the FT232 function is normal?

 Answer:

You can short-circuit TXD and RXD, and then send data in the serial port debugging assistant Windows to see if there is corresponding data returned, if there is, the function is normal; as shown below:

Question:What may cause damage to the FT232 chip?

 Answer:

1) Overvoltage and overcurrent, electrostatic reverse connection, harsh environment, electromagnetic interference and other conditions may cause IC damage:

• Overvoltage and overcurrent: When the FT232 chip receives an excessive voltage shock, the connected circuit or peripherals consume more current than its specification range, and the current protection mechanism inside the chip may cause damage.
• Electrostatic reverse connection: When reverse voltage appears between the pins, or when subjected to electrostatic discharge, its internal circuit may be damaged.
• Harsh environment: Using FT232R under high, low or humid temperature conditions, especially without proper heat dissipation measures, may lead to chip performance degradation, short circuit, or even damage.
• Electromagnetic Interference: A strong electromagnetic interference environment may affect the normal operation of the chip, causing performance problems or even damage.

2) To reduce the risk of chip damage, the following precautions are recommended:

• Use proper supply voltage and current, avoid over-current and over-voltage conditions.
• Avoid electrostatic discharge, use anti-static measures, such as wearing electrostatic gloves.
• Provide sufficient heat dissipation and temperature control to avoid use under extreme temperature conditions.
• Using Industrial grade products, with the protection of shell, isolation, overcurrent and overvoltage, it can resist electromagnetic to a certain extent interference.
