UM232R USB- Serial UART
Development Module
Incorporating Clock Generator Output
and FTDIChip-ID⢠Security Dongle
The UM232R is a development module which uses FTDIâs FT232RL, the latest device to be added to FTDIâs range of
USB UART interface Integrated Circuit Devices.
The FT232RL is a USB to serial UART interface with optional clock generator output, and the new FTDIChip-IDâ¢
security dongle feature. In addition, asynchronous and synchronous bit bang interface modes are available. USB to
serial interface designs using the FT232RL have been further simpliï¬ed by fully integrating the external EEPROM,
clock circuit and USB resistors onto the device.
The FT232RL adds two new functions compared with its predecessors, effectively making it a â3-in-1â 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-IDâ¢) 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 UM232R is supplied on a PCB which is designed to plug into a standard 15.0mm (0.6â ) wide 24 pin DIP socket.
All components used, including the FT232RL are Pb-free (RoHS compliant).
