1 Description
Fastest & Securest USB 2.0 Flash Disk Controller with dedicated 32-bit
microprocessor
The CBM2091 is the USB 2.0 Flash Disk controller with the fastest transfer speed on the market.
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, Mac OS and Linux OS. With device driver installed, it can support Win 98/98SE as well.
Comprehensive applications, such as PC boot up, disk partitions, password check for security disk, are
available as part of our standard mass production software package.
The CBM2091 is available in 48-pin TQFP and 64-pin LQFP package, which are thinnest and smallest
on the market. The 48-pin CBM2091 supports up to 4 flash chips and the 64-pin CBM2091 supports up
to 8 flash chips. Customers can choose different packages to meet their design requirement.
