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.
