    1.產品簡介


    GL3227E   USB 3.2 Gen 1 to e&#8226;MMC HS400 RAID0 Bridge Controller




    GL3227E是一款USB 3.1 Gen 1 eMMC RAID讀卡器,它提供單個LUN(邏輯單元號),可以支持;MMC v5.0、1/4/8bit數據總線、高速SDR/高速DDR/HS200/HS400模式。


    GL3227E集成了高速8051微處理器和高效硬件引擎,可在USB和各種存儲卡接口之間實現的數據傳輸性能。它支持串行外圍接口(SPI),通過USB端口將固件升級到SPI閃存。它還集成了5V至3.3V和3.3V至1.8V/1.2V的穩壓器和功率MOSFET,可以降低系統BOM成本。
