4-channel CompactFlash Card Controller

SM2236

The SM2236 is the world’s highest performance and

the lowest power consumption CompactFlash card

controller. Fully compliant with CFA 6.0, the controller

supports UDMA transfer on True-IDE and PCMCIA

modes, especially designed for professional DSLR.

The SM2236’s ECC can support most major NAND

flash vendor’s new generation SLC/MLC/TLC and

perform global wear-leveling to evenly distribute the

write and erase counts to each block. Incorporating

the advanced ECC and global wear-leveling algorithm,

the SM2236 can operate with various NAND flash

memories/process geometries and maximize the life

expectancy of CompactFlash card.
