SuperSpeed USB3.0 Flash Drive Controller
SM3268
The SM3268 is a USB 3.0 single-channel flash drive
controller designed for Type C/Type A dual connector
application. The controller offers 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 8 NAND flash devices.
The SM3268 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 SM3268 is
available in QFN-64 green package and die form with
manufacturing-ready turnkey solution.
