FT234XD-R Application Circuit

FT234XD-R-Application Circuit

Application Example showing USB to RS232 Converter

An example of using the FT234XD as a USB to RS232 converter is illustrated in Figure above. In this application, a 3V3 TTL to RS232 Level Converter IC is used on the serial UART interface of the FT234XD to convert the 3V3 levels of the FT234XD to RS232 levels. This level shift can be done using line drivers from a variety of vendors e.g. Zywyn. A useful feature on some of these devices is the SHDN# pin which can be used to power down the device to a low quiescent current during USB suspend mode. A suitable level-shifting device is the Zywyn ZT3222F which is capable of RS232 communication at up to 1000k baud.
