Silicon Motion introduces the First Single Chip Controller for Cost Effective USB Portable SSDs

TAIPEI, Taiwan and MILPITAS, Calif.–(BUSINESS WIRE)–Silicon Motion Technology Corporation (NasdaqGS: SIMO) (“Silicon
Motion”), a global leader in NAND Flash controllers and solid-state
storage devices, today launched an external Solid State Drive (SSD)
controller solution with an on-chip USB 3.2 interface, offering high
performance and low power consumption for the next generation of
cost-effective portable and external SSDs.

Current portable and external SSD designs typically employ a stand-alone
SSD with an USB to SATA or PCIe bridge chip for interface between the
SSD and the host. The new SM3282 with on-chip USB 3.2 Gen 1 interface
provides a complete single-chip hardware and software solution
supporting the USB Attached SCSI Protocol (UASP) and 2 NAND channels
with 4 CE (Chip Enables) per channel, enabling up to two terabytes of
storage with the latest generation of 96-layer QLC NAND. The SM3282 also
enables battery powered small form factor portable SSDs while
significantly reducing Bill of Materials (BOM) cost.

“Professional users often rely on high-speed portable storage to get
access to their data on-the-go. Portable SSDs have been inhibited by
high pricing and limited capacity compared to portable HDDs,” said
Wallace Kou, President and CEO at Silicon Motion. “Our new SM3282
controller solution with its USB 3.2 Gen 1 interface enables the
introduction of a new category of cost-effective portable SSDs as higher
performance alternatives to portable HDDs.”

The key features of the SM3282 include:

  • Peak sequential read and write transfer speeds of over 400MB/sec
  • Supports USB type A and type C
  • Compatible with Windows 10, Mac OS 10.x and Linux kernel v2.4
  • Crystal-less design for bill-of-materials cost savings
  • Built-in 3.3V/2.5V/1.8V/1.2V voltage regulators
  • Supports LED for indicating access status
  • 68-pin QFN package

Silicon Motion is showcasing SM3282 in the company’s Computex 2019
private suite and will be sampling to customers in June 2019. For more
