Silicon Motion SM3267: USB 3.0 Controller

Silicon Motion Technology Corporation announced that it has begun sampling its single-channel, high performance controller solution for USB 3.0 flash drives, the SM3267.

By integrating an embedded crystal oscillator and all power ICs, SM3267 reduces the customers’ overall system cost. In addition, it delivers data transfer rate of up to 160MB/s read, a 30% to 50% improvement from most single-channel USB 3.0 flash drive controllers in the market.

“We are very excited to introduce SM3267, our first crystal-less USB 3.0 solution with integrated power ICs,” said Wallace Kou, president and CEO, Silicon Motion. “SM3267 offers superior performance with competitive cost when compared to other USB 3.0 controllers in the market, and we believe our solution will help accelerate the market in transitioning from legacy USB 2.0 flash drives to the latest generation USB 3.0 drives. This is another example of Silicon Motion leading the market in bringing new, advanced technology to the mainstream market. We are pleased to announce that SM3267 has received design-ins from most of our current USB controller customers, including many top-tier OEMs, and we expect SM3267-based USB 3.0 flash drives will be commercially available starting in the fourth quarter of 2013.”

This provides a high performance USB 3.0 controller
capabilities and technologies including:

Data transfer rates of up to 160MB/s read and 60MB/s write

Integrated crystal and power ICs, including a 5V to 3.3V LDO and a 5V to 1.2V DC-DC, allows for 25-30% lower USB flash drive device temperature compares with other USB 3.0 flash controller products in the market.

Lower total BOM costs by up to 15 to 20% by eliminating the crystal oscillator and power ICs

Supports the vast majority of NAND flash, including 2y/1x/1y nm TLC, MLC, high speed Toggle, and ONFI DDR NAND manufactured by Samsung, Toshiba, SanDisk, SK Hynix, Micron and Intel

Passed both USB-IF compliance testing and WHCK (Windows Hardware Certification Kit) tests for Windows 7 and Windows 8

Available in Chip-on-Board (COB) and in a 48-pin QFN green package with manufacturing-ready solutions designed to fit mainstream USB 2.0 flash drive modules.
