The FT232R includes onboard EEPROM, as well as a master clock generator, 3.3-V LDO regulator, reset generator and USB termination resistors. Only two external decoupling capacitors are required for ...

In this case a USB-TTL adapter based around the FTDI FT232R IC: the TTL-232R-3V3-AJ adapter with 12 Mbps USB on one end, and a 3 Mbps UART on the other end.

Future Technology Devices International (FTDI ) is offering a USB-UART bridge which includes onboard EEPROM, master clock generator, 3.3V LDO regulator, reset generator and USB termination resistors.
