CBM2091 can reach theoretical flash access speed limit of over 32MByte/s for read and 20MByte/s for write. The on-the-fly ECC engine is capable of correcting up to 4bytes (32bits), detect 5 or more bytes errors per 528bytes page . For data security, CBM2091 is designed with both hardware and software data protection technology to prevent data corruption even if it is powered off or unplugged during data transfer. The CBM2091 supports all 8 bit and 16 bit NAND/MLC/AG-AND flash memory available in the market. New flash can be supported by software re-configuration. It also supports SPI NOR flash without extra components needed. The CBM2091 has both a) 5V to 3.3V LDO and b) power on reset circuits integrated. Thus greatly reduced BOM cost and eased layout burden. The CBM2091 runs smoothly with all available hosts and PC platforms. Complied with USB specification rev. 2.0, the CBM2091 can be supported without additional driver under Win XP, Win 2000, Windows Me,...
