FT232R - USB UART IC
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.

FT245B USB FIFO ICs
FT245R version recommended for new designs
The FT245B is the 2nd generation of FTDI's popular USB FIFO device and the FT245BL is a lead free version of it. The FT245BQ provides the same functionality as the FT245BL in a QFN-32 lead free package.
