FT232RNQ-REEL

FT232RNQ is an USB full speed to serial UART IC, includes oscillator and EEPROM with 32 pin QFN package. USB to serial designs using the FT232RNQ have been further simplified by fully integrating the external EEPROM, clock circuit and USB resistors onto the device. The FT232RNQ 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 Applications are USB to RS232/RS422/RS485 converters, upgrading legacy peripherals to USB, USB industrial control, USB MP3 player interface, set top box PC–USB interface.
