Embedded USB3.0 Flash Controller

EM3260

The EM3260 is the USB3.0/USB2.0 high performance

Flash drive controller focusing on

embedded/industrial application (eUSB) usage. It

combines high compatibility and high performance to

support dual -channel SLC and MLC NAND Flash

memory in a single chip. The EM3260 complies with

USB3.0 power specifications for bus-powered devices.

The EM3260 supports high capacity (up to 16 Flash

devices) with small form factor.

The EM3260 delivers high data transfer rate, and

ensures data accuracy and reliability with the

powerful ECC engine. The EM3260 is available in

88 pin QFN package.
