TTL-232R General Description

The TTL-232R is a USB to TTL serial converter cable incorporating FTDI's FT232RQ USB - Serial UART interface IC device, the latest device to be added to FTDI's range of USB UART interface Integrated Circuit Devices. It is designed to allow for a fast, simple way to connect devices with a TTL level serial interface to USB.

The FT232RQ chip used by the TTL-232R is housed within the USB 'A' connector. A 1.8 (6 foot) meter cable is terminated with a 6 way 0.1" pitch header socket which provides access to the transmit (Tx), receive (Rx), RTS#, and CTS#, as well as VCC (5V out) and GND.

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 interface designs using the FT232R have been further simplifi ed by fully integrating the external EEPROM, clock circuit and USB resistors onto the device.

TTL-232R Features

• TTL-232R Converter Cable provides a USB to TTL Serial header interface (6 way, 0.1" pitch).
• On board FT232RQ provides single chip USB to asynchronous serial data transfer interface.
• Entire USB protocol handled on the FT232RQ chip - No USB-specific firmware programming required.
• Connect directly to a microcontroller UART or I/O pins
• UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity.
• Fully assisted hardware (RTS#/CTS#) or X-On / X-Off software handshaking.
• Data transfer rates from 300 baud to 3 Megabaud at TTL levels.
• 5V CMOS drive outputs and 5V safe TTL inputs makes the TTL-232R easy to interface to 5V MCU's.
• FTDI's royalty-free VCP allow for communication as a standard COM port and D2XX 'direct' drivers provide DLL application programming interface.
• In-built support for event characters and line break condition.
• Support for FT232R FTDIChip-ID™ feature.
• 256 byte receive buffer and 128 byte transmit buffer utilising buffer smoothing technology to allow for high data throughput.
• FIFO receive and transmit buffers for high data throughput.
• Adjustable receive buffer timeout.
• Integrated 1024 bit internal EEPROM for storing custom USB VID, PID, serial number and product description strings.
• Device supplied preprogrammed with unique USB serial number.
• Support for USB suspend and resume.
• Cable supply voltage comes from USB - no external supply required.
• 5V output allow devices to be powered from the USB port.
• 6 way 0.1" header connector (Tx, Rx, RTS#, CTS#, Vcc, and GND)
• Low USB bandwidth consumption.
• UHCI / OHCI / EHCI host controller compatible
• USB 2.0 Full Speed compatible.
• -40 to +85 operating temperature range.
• Connect to a PC via USB 'A' plug on 1.80 meter (6 foot) cable.
• A 3.3V TTL I/O version is also availalable (TTL-232R-3V3)
• Custom versions also available (subject to MOQ).

TTL-232R Typical Application

• USB to Serial TTL Level Converter
• Upgrading Legacy Peripherals to USB
• Interface Microcontroller UART or I/O to USB
• Interface FPGA / PLD to USB
• Replace MAX232 type level shifters allowing for direct connection of products to PC via USB
• USB Instrumentation PC interface
• USB Industrial Control
• USB Software / Hardware Encryption Dongles
