Original Press Release:
Exar Introduces Maximum Performance (8Mbps) UART First in a Series Addressing High-Speed Data Transmission Requirements of Cutting-Edge Industrial Applications
Fremont, California, January 30, 2006 - Exar Corporation (Nasdaq: EXAR), a leading provider of high-performance, mixed-signal silicon solutions for the worldwide communications infrastructure, announced today its highest-performance Universal Asynchronous Receiver Transmitter (UART). It will be added to Exar's 8-bit serial communications portfolio one of the industry's broadest UART offerings. The eight-channel XR16V798 is the first in a new generation of 8Mbps devices targeted at supporting faster data transmission speeds required by cutting edge industrial applications including remote access servers, network management, factory automation/process control and multi-port RS-232/RS-422/RS-485 communications cards.
"Exar's technology innovations are based on the Company's unique expertise and understanding of the serial communications markets and customer requirements," said Levent Ozcolak, divisional vice president and general manager, Interface Products Division. "For example, the XR16V798's fractional baud rate generator can accept any external clock to generate the desired baud rate; this eliminates the need for an additional clock source and results in saving on both board space and cost."
The XR16V798 is a 2.25V to 3.6V device with 5V tolerant inputs. The device features 64-byte Transmit (TX) and Receive (RX) FIFOs with fully programmable trigger levels, automatic RTS/CTS or DTR/DSR hardware flow control with programmable hysteresis, automatic software (Xon/Xoff) flow control, RS-485 half-duplex direction control with programmable turn-around delay, Intel or Motorola bus interface and sleep mode with a wake-up indicator. It also has the industry standard 16C550 register set, and is pin-for-pin compatible with Exar's XR16L788 (8-channel, 8-bit data bus) device.
"At 8Mbps, the XR16V798 breaks new ground for Exar and offers customers the best overall solution to quickly react to the rapid time-to-market demands of next generation industrial applications." said Eric Nguyen, senior strategic marketing manager, Interface Products Division.
Tools and Support
The XR16V798 is supported by Exar's UART software drivers for popular operating systems including Windows 2000, XP and Linux. With the availability of software drivers and Exar's application support line, UART customers can accelerate implementation by eliminating driver development, testing and diagnostic procedures.
Packages and Availability
The XR16V798 is available now in 100-pin QFP packages at $20.13 for 1,000 pieces. The device operates over the industrial temperature range of -40oC to +85oC.
