MM232R USB to Serial UART Development Module, FTDI Chip

The MM232R is a mini development module for the FT232RQ IC device. It is a little bigger than a USB connector, and provides USB - Serial UART interface in a extremely small form factor. It is ideal for adding a USB interface to existing product designs. Based on the FT232RQ device, the MM232R supports RTS/CTS hardware handshaking and is powered from the USB port. Serial data communication is possible at up to 3MBaud at TTL level. In addition, some of the EEPROM configurable CBUS pins of the FT232R are brought out allowing the MM232R to be used to provide clock signals to external logic.

FTDI Chip USB To UART Development Board

The FTDI Chip USB to UART development board is a miniature kit that uses FTDI’s FT232RQ, which is the latest device to be added to FTDI’s range of USB UART interface integrated circuit devices. It is a USB to serial UART interface with optional clock generator output and with asynchronous and synchronous bit bang interface modes. The USB to serial interface designs uses the FT232RQ and have been further simplified by fully integrating the external EEPROM, clock circuit and USB resistors onto the device. Also, there is a unique number burnt into the device during manufacture and is readable over USB. This forms the basis of a security dongle, which can be used to protect customer application software from being copied.
