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 MLC/SLC NAND 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.

• CompactFlash Card
• PATA Solid State Disk
• High-Speed NAND Storage Package
• 144-pin TFBGA package
• Lead-free and RoHS Compliant

Symmetry Electronics is an authorized Silicon Motion distributor.
