Success Stories: Mobile Enterprise

Overview

The two figures above outline both the original and modified architecture for an enterprise PDA using the Marvell PXA310 application processor, a Hi-Speed USB 2.0 OTG port and Compact Flash (CF) expansion port.

Challenge

Some PDAs are designed with expansion slots, such as Compact Flash, that allow for aftermarket peripherals to be developed, expanding the functionality beyond what is natively supported by the PDA. Over time, a host of peripherals is available in the market supporting a variety of different functions from GPS modules to card scanners to flash memory drives. As companies bring new and enhanced PDAs to market, they must support the expansion interface these peripheral products were developed to support, or risk alienating the consumers that already own those peripherals. However, emerging application processors typically do not have integrated support for these older expansion interfaces.

QuickLogic Solution

QuickLogic’s CSSP approach enabled this PDA manufacturer to gain the performance, cost and battery life benefits of using the latest application processor technology from Marvell. Furthermore, the integration of QuickLogic’s CSSP reduced three devices down to a single device, saving precious PCB space in the PDA.

Results

As a result of using the QuickLogic CSSP, this PDA manufacturer extended the lifetime of the Compact Flash peripherals developed for their PDA by the numerous third party companies, leveraging their R&D investment in the Compact Flash interface.
