The GL826 is a highly integrated USB 2.0single chip card reader controller that supports all popular form factor memory cards, such as CF, MD, SD/MMC, MS, MS PRO, MS PRO-HG, SM/xD. With booming microSD or MMC Mobile cards in the mobile market, we provide the feature of the two independent SD/MMC card interfaces will be benefit to card venders. In addition to dual SD/MMC card interfaces support, GL826 can support CF PIO/UDMA mode, 8GB Class 6 SDHC and MS PRO-HG 8bit to show their fast read/write performance. 128-pin LQFP package is for multi-slot card reader application and can upgrade firmware with external flash. 48-pin LQFP package is mask ROM type for dual-slot card reader application. Both of them will fulfill your requirement in many kinds of application.
