312 MB/s data rate with SD 4.0 UHS-II technology


GL3215 is an USB 3.1 Gen 1 to SD4.0/MMC Single LUN Memory Card Reader Controller and support various types of memory cards, such as Secure DigitalTM (SD), SDHC, miniSD, microSD (T-Flash), MultiMediaCardTM, RS-MMC, MMCmicro and MMCmobile. It also supports high density memory cards (Capacity up to 2TB), such as SDXC, ultra high speed memory cards, SD3.0 UHS-I and the latest generation high speed memory cards SD4.0 UHS-II card.
GL3215 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 3.3V to 1.2V regulators and power MOSFETs which can reduce the system BOM cost.
