EVAL232R

FT232RL USB to RS232

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).
