About FT232RL
The FT232R is the latest device to be added to FTDI?s range of USB UART
interface Integrated Circuit Devices. The FT232R 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
designs using the FT232R have been further simplified by fully
integrating the external EEPROM, clock circuit and USB resistors onto
the device.
The
FT232R 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.
Single chip USB to asynchronous serial data transfer interface.
Entire USB protocol handled on the chip - No USB-specific firmware programming required.
UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity.
Fully assisted hardware or X-On / X-Off software handshaking.
Data transfer rates from 300 baud to 3 Megabaud (RS422 / RS485 and at TTL levels) and 300 baud to 1 Megabaud (RS232).
In-built support for event characters and line break condition.
New USB FTDIChip-ID? feature.
New configurable CBUS I/O pins.
Auto transmit buffer control for RS485 applications.
Transmit and receive LED drive signals.
New 48MHz, 24MHz,12MHz, and 6MHz clock output signal Options for driving external MCU or FPGA.
FIFO receive and transmit buffers for high data throughput.
256 Byte receive buffer and 128 Byte transmit buffer utilising buffer smoothing technology to allow for high data throughput.
Adjustable receive buffer timeout.
Synchronous and asynchronous bit bang mode interface options with RD# and WR# strobes.
New CBUS bit bang mode option.
Integrated
1024 bit internal EEPROM for I/O configuration and storing USB VID,
PID, serial number and product description strings.
Device supplied preprogrammed with unique USB serial number.
Support for USB suspend / resume.

Support for WinCE7.0
Initial functional testing conducted by FTDI has shown that the FTDI drivers function as expected on Windows CE 7.0
Support for older versions of Windows Desktop
NOTE:
Microsoft have ended support for certifying XP and VISTA through their
WHCK test program. As such current builds will still work on XP and
VISTA but are not Microsoft certified.
Differences in Driver API
For
most of these operating systems two types of driver are available:
Virtual COM Port (VCP) drivers and direct (D2XX) drivers. The VCP driver
emulates a standard PC serial port such that the USB device may be
communicated with as a standard RS232 device. The D2XX driver allows
direct access to a USB device via a DLL interface.
To locate the drivers you want to install for a device, select which of the driver types you wish to use (VCPorD2XX)
and then locate the appropriate operating systems. With the exception
of Windows 98 and Windows ME, all devices are supported in each driver
package.
If
a VCP driver is required for Android please refer to the following

Android
