Wireless Datacard

QuickLogic has multiple CSSP solutions for the USB-based wireless data dongle market. Starting from our highly integrated, low power platforms that contain unique combination of programmable fabric technology and hard-wired logic, QuickLogic then customizes these platforms with a variety of proven system blocks (PSBs) in order to meet specific customer requirements. This breadth of functionality gives us the ability to quickly deliver a customer-specific design with the right combination of functionality, performance, size, and cost without the delays and expense that characterize other custom design approaches.

Trend

• A driving force behind the rapid adoption of 3G HSxPA mobile broadband has been the availability of user-friendly USB modems as a replacement for clunky PCMCIA cards
• Increased speeds have evolved where today’s UMTS HSxPA network, comprised of HSDPA (High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access) is becoming the dominant technology
• With the release 7 of the 3GPP specification, speeds are increased up to 28Mbits/s
• The user and operator requirements to add onboard and/or removable non-volatile flash storage for preloading of applications or for user storage area becoming a must have on next generation USB dongles
• Mobile TV gaining momentum with varying local standards DVB-H, T-DMB, ISDB-T and Media Flow

Challenges

• Integration of multiple radios that required different interfaces due to cost, performance and power constraints
• Non-Volatile memory performance
• Maintaining system performance under USB power specification
• Adopting an architecture that is scalable and flexible to meet the rapid changing demands of the market

Solution

• QuickLogic provides Hi-Speed USB2.0 with integrated PHY, SDHC/eMMC for support for managed NAND and MicroSD, additional SPI ports and its innovative SPIDA (Smart Programmable Integrated Data Aggregator) system block
• SPIDA enhances memory throughput, which greatly increases performance from USB to MicroSD/Managed NAND
• QuickLogic is also working on a number of security blocks which can be used in association with the SPIDA block to offer various levels of data protection to assist in security applications
