QuickLogic has released a proven system block for an SDIO client. This block, part of QuickLogic's functional library for its Customer Specific Standard Product (CSSP) platforms, enables a range of accessories for mobile devices utilizing the popular SD memory card and SDIO peripheral interface.
QuickLogic's CSSP approach blends fixed logic blocks with an array of low-power customizable building blocks (CBBs) for implementing additional standards-based or custom functions. This approach offers development teams a customizable platform that addresses the need to meet cost, battery life, and PCB-space requirements, while also maintaining the flexibility to evolve designs as market demands change in the future. Quicklogic's CSSP platforms include the PolarPro and ArcticLink platform families, offering a range of options in size and capacity.
As consumers demand higher levels of integration, more functions are put into single devices such as smartphones, personal media players (PMP) and personal navigation devices (PND). The same trend is also seen in the accessory market. Expansion cards and thumb drives are integrating multiple radios for Wi-Fi, mobile TV, and other wireless technologies, along with flash memory storage for data and multimedia content.
The most commonly used interfaces in mobile devices are high speed SD/SDIO and USB. The new SDIO client system block allows QuickLogic to expand its served available market from host-side applications to the accessory market on the client side.
The SDIO client solution is available immediately as part of QuickLogic's CSSP proven system block library. For more information on QuickLogic's CSSP capabilities and platforms, please visit www.quicklogic.com/cssp.
