FT232R USB UART I.C.
Incorporating Clock Generator Output
and FTDIChip-ID⢠Security Dongle
The FT232R is the latest device to be added to FTDIâs range of USB UART interface Integrated Circuit Devices. The
FT232R is a USB to serial UART interface with optional clock generator output, and the new FTDIChip-ID⢠security
dongle feature. In addition, asynchronous and synchronous bit bang interface modes are available. USB to serial
designs using the FT232R have been further simpliï¬ed by fully integrating the external EEPROM, clock circuit and
USB resistors onto the device.
The FT232R adds two new functions compared with its predecessors, effectively making it a â3-in-1â chip for some
application areas. The internally generated clock (6MHz, 12MHz, 24MHz, and 48MHz) can be brought out of the
device and used to drive a microcontroller or external logic. A unique number (the FTDIChip-IDâ¢) is burnt into the
device during manufacture and is readable over USB, thus forming the basis of a security dongle which can be used
to protect customer application software from being copied.
The FT232R is available in Pb-free (RoHS compliant) compact 28-Lead SSOP and QFN-32 packages.
