FT232R USB UART I.C.
Incorporating Clock Generator Output
and FTDIChip-ID™ Security Dongle
The FT232R is the latest device to be added to FTDI’s 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 simplified 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 “3-in-1” 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-ID™) 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.
