1 Description
Most flexible SD/MMC memory card Controller with dedicated 32-bit
microprocessor
The CBM3086 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.
CBM3086 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.
CBM3086 can reach theoretical flash access speed up to 20MByte/s for read and 20MByte/s for
write. The on-the-fly ECC engine is capable of correcting and detecting up to 30bit errors per
512/1024 bytes page. For data security, CBM3086 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 CBM3086 supports all SLC/MLC/TLC 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 CBM3086 runs smoothly with various hosts. Substantial tests have been made to make sure
the compatibility with different hosts.
