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.
