GL3220 is a super speed USB 3.1 Gen 1 compliant Mulit-LUN card reader controller which can support various types of memory cards, such as CompactFlashTM, Secure DigitalTM (SD), SDHC, miniSD, microSD (T-Flash), MultiMediaCardTM (MMC), RS-MMC, MMCmicro, MMCmobile, Memory StickTM (MS), Memory Stick DuoTM (MS Duo), High Speed Memory StickTM (HS MS), Memory Stick PROTM (MS PRO), Memory Stick PROTM Duo (MS PRO Duo), Memory Stick PRO-HGTM (MS PRO-HG), MS PRO Micro and xD-picture card on one chip. It also supports next generation high density memory cards (Capacity up to 2TB), such as SDXC and Memory Stick XC.
The GL3220 integrates a high speed 8051 microprocessor and a high efficiency hardware engine for the best data transfer performance between USB and various memory card interfaces. It supports ISP (In System Programming) for firmware upgrade from the external SPI Flash via USB port. It also integrates 5V to 3.3V and 3.3V to 1.2V regulators and power MOSFETs which can reduce the system BOM cost.
