Evaluation Module
Incorporating Clock Generator Output
and FTDIChip-ID™ Security Dongle
The EVAL232R is a USB to RS232 evaluation module for FTDI’s FT232RL USB - Serial UART interface IC device, the
latest device to be added to FTDI’s 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-ID™
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 simplified 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 “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 EVAL232R is supplied on a 61.0mm x 32.0mm (2.40” x 1.26”) PCB. All components used, including the FT232RL
and RS232 level converter IC are Pb-free (RoHS compliant).
