Fremont, California " Exar Corporation (Nasdaq: EXAR), a leading provider of high-performance, mixed-signal silicon solutions for the worldwide communications infrastructure, today announced the industry's first multi-channel 66MHz PCI 3.0 compliant Universal Asynchronous Receiver Transmitter (UART) product family.
Recognizing the growing market adoption of higher speed interconnects, Exar leveraged its already extensive product portfolio and seasoned understanding of, and connections to, customer design requirements to develop the XR17V25x family [where "x" stands for the number of channels]. Targeting the computer and telecom server market, the 66MHz PCI provides an ideal solution for system management and administration of applications where continuous redundancy and Quality of Service at higher bus clock speeds are critical. The 66MHz portfolio is ideal for remote access servers, storage, instrumentation, serial port expansion, embedded systems, factory automation and process control.
"The serial port is still the easiest and most reliable connection used for system configuration, diagnostics and alarm functions," said Levent Ozcolak, acting general manager, Interface Products Division. "While much attention is devoted to faster bus technologies such as PCI Express, there remains a large installed base of conventional PCI interface users. Here, Exar continues to demonstrate its product innovation and commitment as a leading supplier of interface products enabling designers to develop current and future generations of communication product solutions."
Optimized for both higher performance and lower power, the XR17V25x products provide a direct interface to the PCI bus eliminating the need for a PCI-Local bus bridge, reducing system cost and board space requirements.
"As demand for bandwidth and speed continues to grow, the XR17V25x family enables customers to respond to rapidly changing market conditions, while minimizing risk and uncertainty," said Rita Horner, strategic marketing manager, Interface Products Division. "The XR17V25x provides a seamless migration path for the existing 33MHz PCI interface product users."
First in the series of single chip multi-channel 66MHz devices is the eight-channel XR17V258. The device features 3.3V supply, fractional Baud Rate Generator, PCI Bus Power Management 1.1 support, 16-bit programmable timer/counter, and 32-bit of data loading and unloading. It is register-set, package and pin compatible with Exar's existing 33MHz XR17C158 (5V) and XR17D158 (Universal) PCI UART devices.
The XR17V258 consists of eight independent UART channels with 64 bytes of Transmit (TX) and Receive (RX) FIFOs and a global interrupt source register for faster interrupt parsing of all the channels within the device. In addition to the fifth generation set of configuration registers, the 66MHz device has new enhanced registers, and meets the high bandwidth and power management requirements of communication systems. Each UART channel includes a fully programmable TX and RX FIFO level triggers, FIFO level counters, an automatic hardware and software flow control, wireless infrared (IrDA) encoder/decoder, and an automatic RS-485 half-duplex direction control output for hardware and software design simplification. The XR17V258 also offers sleep mode with wake-up indicator feature that allows for lower power consumption.
Tools and Support
The XR17V25x series is supported by Exar's market proven PCI software drivers that support leading operating systems. With the availability of software drivers and Exar's application support line, PCI UART customers can accelerate their time to market by eliminating driver development, testing and diagnostic procedures.
Prices, Packages and Availability
The eight-channel device, XR17V258 is offered in a 144-pin TQFP package, and is priced at $26 in 1,000 pieces quantities. The device is available for sampling now. Additional multi-channel devices in this product family will be offered later this year.
