FT232RL

Product Summary

The FT232RL is a USB to serial UART interface device which simplifies USB to serial designs and reduces external component count by fully integrating an external EEPROM, USB termination resistors and an integrated clock circuit which requires no external crystal, into the FT232RL. It has been designed to operate efficiently with a USB host controller by using as little as possible of the total USB bandwidth available.
