Product Description

The EVAL232R is a USB to RS232 converter module based on the FT232RL IC. The module features both a USB type B connector and an RS232 based DB9 connector interface. The FT232RL device is used to provide the USB to serial UART interface conversion. An onboard level shifter is used to provide RS232 signal levels. Additional header pins on the board provide access to the FT232RL device's configurable CBUS interface pins on the FT232RQ. The EVAL232R is supplied on a 61.0mm x 32.0mm (2.40” x 1.26”) PCB.

The module is powered from the USB interface with 5V and 3V I/O interfacing supported on the CBUS I/O pins. The DB9 RS232 interface supports full RTS/CTS flow control, and DTR/DSR hardware handshaking. DCD and RI signals are also available. RS232 communication is possible at up to 250kBaud. LEDs are fitted to indicate traffic activity.

The EVAL232R is a USB to RS232 evaluation module for FTDI’s FT232RL USB - Serial UART interface IC device, the most recent 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 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 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.
