Description:
SK6222是一個效能加強版的隨身碟控制器,它能符合USB3.0的規格並能以極低功率來滿足USB bus-power的需求。同時向下兼容於USB2.0與USB1.1的規範。
透過先進的電源管理控制方式設計,SK6222能提供非常小的功耗,並且支援從U0到U3的電源分級。
SK6222為支援單通道(Single Channel)的設計,並同時支援大部分的SLC, MLC and TLC。為了展現出USB3.0的高速傳輸,SK6222支援DDR NAND的界面設計,提供了高速傳輸下的儲存產品應用。同時為了保證資料的準確性與完整姓,內建了ECC (Error Collection Module)。
SK6222內部整合了32-bit的微處理器,提供了進階軟體的運\算處理及增加客制化的彈性。加入了Microsoft Password Silo (PS) defined by IEEE 1667,使得使用者可以在微軟的作業系統下,資料加密的安全性,避免與降低了遺失隨身碟而造成資料的損失或個人隱私的損害。
SK6222提供了較少的接角(Pin count),並且可以符合市面上USB2.0的外殼,讓客戶在開發過程中,無痛導入的便利及競爭優勢。 Features: USB3.0 interface
