FT232RNQ – USB UART IC
The FT232RNQ is added to FTDI’s range of USB UART interface Integrated Circuit Devices. The FT232RNQ 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 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 copied.
FT245RNQ – USB FIFO IC
The FT245RNQ is a USB to parallel FIFO interface, with the new FTDIChip-ID™ security dongle feature. In addition, asynchronous and synchronous bit bang interface modes are available. USB to parallel designs using the FT245RNQ have been further simplified by fully integrating the external EEPROM, clock circuit and USB resistors onto the device.
