描述 Description

Fastest & Securest USB 2.0 Flash Disk Controller with dedicated 32-bit

microprocessor

The CBM2093 is the USB 2.0 Flash Disk controller with the fastest transfer speed on the market.

CBM2093 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 8/15bits per 512 bytes page . For data

security, CBM2093 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 CBM2093 supports all 8 /16 bit BUS wide NAND flash memory available in the market. New

flash can be supported by software re-configuration.

The CBM2093 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 CBM2093 runs smoothly with all available hosts and PC platforms. Complied with USB

specification rev. 2.0, the CBM2093 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 CBM2093 is available in 48-pin TQFP and 64-pin LQFP package, which are thinnest and

smallest on the market. The 48-pin CBM2093 supports up to 4 flash chips and the 64-pin

CBM2093 supports up to 8 flash chips. Customers can choose different packages to meet their

design requirement.
