The FT232R is available in Pb-free (RoHS compliant) compact 28-Lead SSOP and QFN-32 packages. 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 internally generated clock (6MHz, 12MHz, 24MHz, and 48MHz) can be brought out of the device and used to drive a microcontroller or external logic. The FT232R adds two new functions compared with its predecessors, effectively making it a “3-in-1” chip for some application areas. 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. In addition, asynchronous and synchronous bit bang interface modes are available. The FT232R is a USB to serial UART interface with optional clock generator output, and the new FTDIChip-ID™ security dongle feature. The FT232R is added to FTDI’s range of USB UART interface Integrated Circuit Devices.
