MM232R Mini USB- Serial
UART Development Module
Incorporating Clock Generator Output
and FTDIChip-ID™ Security Dongle
The
MM232R
is a minature 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).
