Replacing FT232R with CY7C65213 USB-UART LP Bridge Controller - KBA85921

Version: *E

 

Question:

Is the CY7C65213 USB-UART LP Bridge Controller pin-compatible with FT232R? 

 

Answer:

Yes, the CY7C65213 USB-UART LP Bridge Controller is pin-to-pin compatible with the FTDI FT232R, and it can be used as a drop-in replacement for the FTDI FT232R. However, there are some differences between CY7C65213 and FT232R.

Table 1 summarizes the key similarities and differences between the two ICs.

In addition to the above, note the following:

  • FT232R inputs have an internal 200-kΩ pull-up resistor to VCCIO.
  • CY7C65213 inputs have an internal 5.6-kΩ pull-up resistor to VCCIO.
  • FT232R supports bit-bang mode read and write operation while CY7C65213 does not.
