The Highest SATA 6Gb/s performance
with the Best BOM Cost Competitiveness


GL3321G(-11) is a high performance USB 3.1 Gen 1 to SATA 6Gb/s storage controller for personal storage (external HDD/SSD enclosure), ODD player, media player, and set-top-box applications. It integrates Genesys Logic owned design USB 3.1 Gen 1/2.0 PHY and SATA PHY which provides more design flexibility and quality. From system point of view, GL3321G(-11) can meet EU Eup regulation on standby power consumption (0.5W) and it also passes Microsoft WHQL1.6 verification program, which can reduce time-to-market efforts for system manufacturers. GL3321G(-11) also integrates the voltage regulators to provide minimal active components on RBOM.
