The SM3282 is a single chip solution equips with embedded USB 3.2 Gen 1 interface and support USB
Attached SCSI Protocol (UASP). With the fully integrated hardware and software, SM3282 enables the ultra
high-speed data transfer between PC and external SSD for next generation applications. Because it can
interface directly to the host without the need for an external bridge chip, it enables manufacturers of external
SSDs to reduce system size and lower their Bill-Of-Materials (BOM) cost.
The SM3282 delivers peak sequential read and write transfer speeds up to 440MB/s and 430MB/s, while
enabling new SSD designs to take full advantage of high-density NAND Flash, including the latest generation
of 9x-layer QLC NAND.
Silicon Motion supplies the SM3282 with a production-ready reference design, providing a complete turnkey
solution which gives customers a fast time-to-market.
