Exar Launches Industry's Fastest (25 Mbps) and Most Integrated Universal Asynchronous Receiver Transmitter (UART) Series with PCIe 2.0 Gen 1 Compliant Bus Interface

Two-, Four-, and Eight-Channel UARTs with On-Chip PCIe PHY and PCIe Digital Controller -- Series Builds On Exar's Market-Leading PCI UART Portfolio

FREMONT, Calif., Nov. 16 -- Exar Corporation (NASDAQ:EXAR) announced the industry's fastest PCIe 2.0 Gen 1 UARTs with up to 25 Mbps serial data rate. The series is composed of three devices: XR17V352/354/358 which offers distinguishing features customers require for next generation applications. These features include an on-chip PCIe PHY and PCIe digital controller, support for large FIFO sizes (256 bytes), optimized software drivers, and a complete single-chip endpoint solution eliminating the requirement for external PCIe-PCI bridge devices. The XR17V352/354/358 series is ideal for remote access servers, storage network management, factory automation, and Point-of-Sales (POS) systems.

"The XR17V352/354/358 series is the industry's most advanced and complete PCIe endpoint solution supporting up to 25 Mbps UART data rates, 16 GPIOs and large FIFO sizes," said Levent Ozcolak, vice president, Interface Product Line. "These highly differentiated single-chip offerings provide system architects PCIe connectivity for their next generation OEM products while presenting a cost optimization opportunity for existing designs using PCIe-PCI bridges with PCI UARTs."

Series Details

The XR17V352, XR17V354, and XR17V358 have a PCIe interface, which is compliant with the PCIe 2.0 specification. The XR17V352, at 9mm x 9mm is the smallest two-channel compliant device in the industry. All the devices share a common set of features including large FIFO sizes of 256-byte TX /RX that optimize overall data throughput, automatic hardware (RTS/CTS or DTR/DSR) flow control, automatic software (Xon/Xoff) flow control, RS-485 half duplex direction control with programmable turn around delay, and Infrared (IrDA 1.1) data encoder/decoder. In addition, the series shares other features including a fractional baud rate generator, 16 GPIO pins, and multi-drop mode with auto half-duplex transceiver control. Software drivers are available for Windows 2000, XP, Vista, and Windows 7, QNX as well as Linux. In order to minimize overall power consumption, these devices operate from a single 3.3V volt power supply with a built-in buck regulator that can be used to power the core operating at 1.2V.

"The availability of complete driver support for a wide range of operating systems further simplifies system design and shortens time-to-market for new OEM product introductions," said Rakesh Bhatia, senior manager, strategic marketing, Interface Product Line. "This marks another step in Exar's continuing effort to extend the reach of its serial communications expertise to offer additional I/O connectivity options for high performance systems."
