SM3267 Datasheet
Revision 1.0 5 Overview
1. Overview
1.1 Product Description
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 QFN-48 and E-LQFP-48 green packages with manufacturing-ready
turnkey solution.
