Super Speed USB3.0 Flash Memory Controller

SM3260

The SM3260 is the USB3.0/USB2.0 Flash drive

controller that combines high compatibility and high

performance to support dual -channel SLC, MLC and

TLC NAND-type Flash memory in one chip. The

controller also supports high speed Toggle mode and

ONFI 2.x DDR NAND Flash. Based on 0.11

μm

fabrication technology and low-power consumption

considerations, the SM3260 complies with USB3.0

power specifications for bus-powered devices. In

conjunction with USB3.0 Flash drive applications, the

SM3260 supports high capacity (up to 16 Flash

devices) with small form factors

, “write protection”

functionality, PC boot-up from USB Flash drive,

password protection, IEEE 1667 password silo

function, and secured partitioning functions.

The SM3260 delivers high data transfer rate, and

ensures data accuracy and reliability with the

powerful ECC engine which can overcome the

read/write disturbances in 3xnm and 2xnm MLC / TLC

flash. The SM3260 is available for QFN 64 pin(4CE

per channel) / 88 pin(8CE per channel)

– package

with a manufacturing-ready turnkey solution.
