  3. USB UART • XR21V1410IL16-F – single channel USB UART • Industry smallest package, QFN-16 • XR21V1412IL32-F – two channel USB UART • Industry smallest package, QFN-32 • XR21V1414IM48-F – four channel USB UART • Industry smallest package, TQFP48 Company Confidential

  4. USB Basics • What is USB? • USB is a serial bus standard that allows devices to connect to a host computer • Data rates : Low Speed-1.5 Mbps, Full Speed(FS)-12 Mbps, High Speed (HS)- 480 Mbps • Connection (4 Wires) • Vbus - nominally 5V • GND • D+ • D- • A simple, cost effective way to add UARTs to a system Company Confidential

  5. Target CPUs with USB Interface • Most new microcontrollers • Atmel, Microchip, Freescale low end microcontroller have USB ports and few or no UART ports • Almost all microprocessors released in the last five years • Hitachi-Renesas SH series • Motorola-Freescale Coldfire series • IDT RC series • Most Intel CPUs • Most IBM CPUs • Also target FPGAs & custom ASICs with USB/UART ports Company Confidential

  6. Products using processors with USB • Cell phones (especially PDA & pocket PC type) • DVD player, DVR, set-top boxes • Mid to high end PC monitors • Docking stations • PMP, PVP • Health diagnostics meters • PCs, Laptops & Netbooks • Industrial POS systems and handhelds Company Confidential

  8. USB UARTs – Key Features USB 2.0 Compliant Interface 12 Mbps USB full-speed data rate Suspend, resume and remote wakeup operations Capability to support attributes Smallest Package in industry Software drivers support including source code Enhanced Features Data rates up to 12 Mbps on UART Fractional Baud Rate Generator 128 byte TX FIFO, 384 byte RX FIFO 7 or 8 data bits, 1 or 2 stop bits, parity Automatic Hardware and Software Flow Control Multidrop modes Selectable GPIO or Modem I/O Internal 48 MHz clock Company Confidential

  9. Benefits • Why use a USB UART? • High performance at lower supply voltage • 12Mbps (3.3V) • Overall System Cost Reduction • FBRG • No crystal needed • USB is a simpler and easier interface to design (4 wire) • Shorter Time To Market • Easier to add UARTs than to upgrade to new CPU Company Confidential

  10. Exar USB Advantage • Lowest BOM cost • Smallest packages • Complete Software support • Windows, Linux and MAC • Power Management expertise and support • USB suspend mode supported • Fractional Baud Rate Generator • Achieve desired baud rate • NO external crystal needed Exar’sValue proposition is to deliver the lowest cost solution with additional distinguishing features Company Confidential

  11. USB UART Target Markets • Consumer Segment • Cellular Handsets • Portable devices (GPS, PMP, PDAs, etc.) • PC/Laptop add-ons (docking stations, plug-in adapters) • Industrial Segment • Card/Barcode Reader • Gate Access • Add-on Cards • Commercial Segment • Point Of Sales Systems • Security surveillance cameras • Embedded Segment • Health diagnostics meters • Embedded computing applications Company Confidential

  12. USB UART Application Example 1 • Add additional UART port to embedded application • to communicate with serial peripherals or other systems MCU USB Master RS-232 TXCVR USB Interface UART XR21V1410 RS-232 TXCVR UART Company Confidential

  13. Application Example 2 – Medical Equipment XCVR UART UART XCVR Console XCVR UART UART XCVR USB Legacy Bedside Devices Company Confidential

  14. Application Example 3 - Industrial Controls ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) Stand-alone box with USB UART/s (Device Server) RS-485 PLC USB RS-485 PLC PLC PLC Company Confidential Company Confidential 14
