Introduction
The MM232R is a miniature development module which uses FTDI‟s FT232RQ, the latest device to be
added to FTDI‟s range of USB UART interface Integrated Circuit Devices. The FT232RQ 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 FT232RQ have been further simplified by fully integrating
the external EEPROM, clock circuit and USB resistors onto the device. The FT232RQ 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
MM232R is supplied on a ultra-small 18.0mm x 21.5mm (0.7” x 0.8”) PCB. The module board
interface is brought out on16 PCB header pins which are on a 2.55mm (0.1”) pitch. All components
used, including the FT232RQ are Pb-free (RoHS compliant).
