Six Device Family Offers System Architects Multiple Design Options

Composed of six different devices, the XR16Mxxx series includes the XR16M570, XR16M580, XR16M670, XR16M680, XR16M770 and XR16M780. All these devices share a common set of features including Auto RTS/CTS Hardware Flow Control, Auto XON/XOFF Software Flow Control, TX/RX FIFO counters, different TX and RX baud rates, Fractional Baud Rate Generator, Auto RS-485 Half-Duplex Direction Control, Multidrop mode with address detect, and Infrared mode. All the devices have a PowerSave mode which reduces the sleep current to a minimum during sleep modes. The XR16M570/580 series are 16-byte FIFO devices; the XR16M670/680 series are 32-byte FIFO devices and the XR16M770/780 are 64-byte FIFO devices. The XR16M570/670/770 series is compliant with the Intel bus interface, while the XR16M580/680/780 is compatible with both the Intel and Motorola bus interface.

 

Interface Products

Exar has one of the broadest portfolios of high performance interface solutions including UARTs, serial transceivers – RS-232, RS-485, and multi-protocol – and integrated UART/transceiver combinations. For chip-to-chip or system-to-system connections, Exar’s single and multi-channel interface ICs provide immediate competitive advantages to designers: low power, reduction in board space requirements, increased bandwidth capacity and enhanced product features. Interface devices are found practically everywhere including point-of-sale (POS) terminals, digital televisions, industrial automation equipment, handheld devices and networking environments.

 

Tools and Support

Evaluation boards, reference designs, software drivers and Exar’s proprietary firmware for the wireless UART chipset are available. With the availability of these tools and Exar’s application support line, UART customers can accelerate implementation by eliminating driver development, testing and diagnostic procedures.
