SuperSpeed USB3.0 Flash Drive Controller
SM3267
The SM3267 is a USB 3.0 single-channel flash drive
controller offering high performance and high
compatibility for SLC, MLC, TLC, and high-speed
Toggle and ONFI DDR NAND. For USB 3.0 Flash
Disk applications, this controller supports high
capacity of up to 4 NAND flash devices.
The SM3267 delivers high data transfer rate, and
ensures data accuracy and reliability with the
powerful ECC engine which can overcome the
read/write disturbances on new generation NAND. By
integrating an embedded crystal and other
components, the controller can reduce customer
overall cost at a system level. The SM3267 is
available in 48-pin QFN green package with
manufacturing-ready turnkey solution.
