Embedded USB2.0 Flash Controller

EM3255

The EM3255 is a USB Flash controller focusing on

embedded/industrial application (eUSB) usage. It

combines high compatibility and performance to

support single-channel SLC and MLC NAND Flash

memory in a single chip. The EM3255 complies with

USB2.0 power specifications for bus-powered devices.

The EM3255 controller delivers an extremely reliable,

high data transfer rate through the BCH ECC engine

to reduce read/write disturbance errors. Combining

a 5-3.3V regulator and power-on-rest feature, the

EM3255 maximize efficiency and reduces overall

BOM costs. The EM3255 is available in 48-pin

LQFP packages.
