Universal Connectivity: USB

Introduction

The Universal Serial Bus (USB) interface has become the industry standard for connectivity in the world of computing and consumer electronics. Stemming from the PC industry, USB was designed to replace legacy serial and parallel interfaces. More recently, the USB standard has been widely adopted by mobile devices as the high speed interface for multimedia, data transfer and synchronization. The latest USB 2.0 standard supports Hi-Speed with up to 480Mbits/sec throughput. The On-The-Go capability allows two devices to connect to each other without having a computer involved.

QuickLogic USB solutions combine a Hi-Speed USB 2.0 OTG controller with a Hi-Speed USB PHY, making it the most complete USB solution in the market. It also supports the latest UTMI+ Low Pin Interface (ULPI), a low pin-count USB interface between the USB link layer and USB Transceiver Macrocell (PHY). ULPI is designed to drive down a system cost, routing complexity and board space. A “Pseudo-PHY” can be implemented in the low power customizable building blocks to enable a PHY-less interchip ULPI interconnect.

wired LAN Ethernet: PCI

Introduction

Ethernet (10/100) is clearly the prevalent Local Area Networks (LAN) technology in the worlds computer networking market. With the high adoption rate of Ethernet into the networking arena, it is now also making its way into the embedded market. The primary challenges in the embedded world are connectivity and power. Most application processors do not support the PCI interface that is most common in today’s LAN modules. Therefore, a companion device is required to support this in the embedded environment.

QuickLogic has developed a low power connectivity solution to address such challenges and provide a seamless solution to bridge from the application processor to Ethernet LAN controllers over a PCI interface. Many networking semiconductor vendors provide PCI-based Ethernet controllers with integrated PHY, for example, the 82551ER Fast Ethernet Controller from Intel. QuickLogic’s PCI solution supports 32-bit/33-MHz Host/Master/Target controller with built-in DMA engine to interface to these Ethernet controllers.

Highlights

PCI solution supports:

  • Leverage low-cost PCI based peripherals
  • Up to 264 MB/s PCI bus performance with zero wait states
  • Master and target functions for 32-bit at speeds of 33 and 66MHz
  • Fully compliant to PCI specification 2.3 and Compact PCI compatible
  • Hot swap friendly silicon

PCI Solution

Applications

  • Ultra Mobile PC (UMPC) and Mobile Internet Device (MID)
  • Fast LAN data transfer for enterprise PDA, portable Point-of-Sales (ePos) terminals, portable scanners and printers
  • Set-top boxes, home network servers and gateways
  • Mobile device docking stations

USB Hub

Introduction

As USB becomes the universal connectivity interface for mobile devices, more USB ports are required between the host and various peripherals such as keyboards, mice, cameras and printers. The USB specification defines a hub topology to support port expansion. A USB hub has one upstream root port and multiple downstream peripheral ports. All peripherals connected to the downstream ports share the same bandwidth provided by the upstream port.

QuickLogic’s ArcticLink solution platform provides a single Hi-Speed USB OTG port. If a given system requires multiple USB connections, the low power customizable building blocks can be used to implement a multi-port USB hub. The exact number of downstream ports can be configured based customers specific requirements to save resources and power. Each downstream port can support Full-Speed USB peripherals.

Highlights

USB Hub solution supports:

  • Hi-Speed USB upstream port with built-in Hi-Speed USB PHY
  • Each downstream port supports Full-Speed at 12 Mb/s and Low-Speed at 1.5 Mb/s operation
  • The number of downstream ports is customizable
  • Transaction Translator (TT) optimized for maximum bandwidth utilization

USB Hub Solution

Applications

  • Keyboard, mice and other peripheral connections for smartphones, Ultra Mobile PC (UMPC) and Mobile Internet Devices (MID)
  • Smartphones, PDA and mobile PC Docking Stations
  • Set-Top boxes and home network gateway
  • Multiple radio interfaces for data cards and express cards
