ID:CBM3082

  The CBM3082 is the most flexible SD/MMC memory card controller on the market. The proprietary 32 bit processor was specially tailored to handle both SD/MMC protocol and Flash access. Software change can be made easily on site to support new flash or solve potential compatibility issue. 

   CBM3082 support SD2.0 and MMC 4.2 standard. Which are backward compatible to the earlier SD/MMC version, such as SD1.0, SD1.01, SD1.1, and MMC 3.31, MMC4.0, MMC4.1 etc. Up to speed class 6 can be achieved with certain Flash type. CPRM is supported for SD card. It also supports sleep mode, which can cut down power consumption significantly.With dual-channel mode enabled, CBM3082 can reach theoretical flash access speed limit of 24MByte/s for read and 16MByte/s for write. The on-the-fly ECC engine is capable of correcting and detecting up to 8bit errors per 528bytes page. For data security, CBM3082 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 CBM3082 supports all NAND/MLC flash memory available in the market. New flash can be supported by software re-configuration. Card with capacity up to 32GB can be made when configured as SDHC card. Card with capacity up to 128GB can be made when configured as MMCHC card. The CBM3082 runs smoothly with various hosts. Substantial tests have been made to make sure the compatibility with different hosts. 
    The CBM3082 is available in 48-pin TQFP and 48-pin QFN package, which are thinnest and smallest on the market. The 48-pin CBM3082 supports up to 4 flash chips. Customers can choose different packages to meet their design requirement.
