In addition, asynchronous and synchronous bit bang interface modes are available. The FTR adds two new functions compared with its predecessors, effectively making a "3-in-1" chip for some application areas. The internally generated clock 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-IDTM 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. In-built support for event characters and line break condition. Auto transmit buffer control for RS applications.

Integrated 3. Integrated USB resistors. Integrated power-on-reset circuit. Fully integrated clock - no external crystal, oscillator, or resonator required. UART signal inversion option. USB bulk transfer mode. Low operating and USB suspend current. Low USB bandwidth consumption. Windows CE. The drivers listed above are all available to download for free from the FTDI website.

This section summarises the enhancements and the key features of the FTR device. For further details, consult the device pin-out description and functional description sections. The clock circuit has now been integrated onto the device meaning that no crystal or ceramic resonator is required.

However, if required, an external 12MHz crystal can be used as the clock source. These three resistors have now been integrated onto the device. This pin required an external R-C filter. Transmit and Receive Buffer Smoothing - The FTR's byte receive buffer and byte transmit buffer utilise new buffer smoothing technology to allow for high data throughput. There is also the option to bring out bit bang mode read and write strobes see below. The device is supplied with the most commonly used pin definitions preprogrammed - see Section 10 for details.

Data packets can be sent to the device and they will be sequentially sent to the interface at a rate controlled by an internal timer equivalent to the baud rate prescaler. This option will be described more fully in a separate application note. Synchronous Bit Bang Mode - Synchronous bit bang mode differs from asynchronous bit bang mode in that the interface pins are only read when the device is written to.

Thus making it easier for the controlling program to measure the response to an output stimulus as the data returned is synchronous to the output data. An application note describing this feature is available separately from the FTDI website. Search Circuit. Section Supplier Datasheet. Toggle navigation Digchip. Contact FTDI for availability.
