SM3261
The SM3261 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 SM3261 supports Windows To Go, an enterprise
feature of Windows 8 that enables the creation of a
Windows To Go workspace which can be booted from
a USB flash drive on any PC running Windows 7 or
Windows 8.
The SM3261 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.
The SM3261 controller is available in 48-pin QFN
green package with manufacturing-ready turnkey
solution.
