1 Description

Fastest & Securest USB 2.0/USB1.1 Flash Disk Controller with dedicated 32-bit

microprocessor

The CBM2080 is the fastest, securest USB 2.0 Flash Disk controller on the market. With dual-channel

mode enabled, CBM2080 can reach theoretical flash access speed limit of 22MByte/s for read and

20MByte/s for write. For CBM1180/CBM1183, it can reach 1.0Mbytes/s write and 1.1Mbytes/s read.

The on-the-fly ECC engine is capable of correcting up to 3bytes (24bits), detect 4 or more bytes errors

per 528bytes page . For data security, CBM2080/CBM1180/CBM1183 are 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 CBM2080/CBM1180 supports all NAND/MLC/AG-AND flash memory available in the market,and

the CBM1183 supports all NAND/MLC flash memory available in the market. New flash can be

supported by software re-configuration.

The CBM2080/CBM1180/CBM1183 runs smoothly with all available hosts and PC platforms. Complied

with USB specification rev. 2.0, the CBM2080/CBM1180 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 mass production software package.

The USB2.0 flash disk controller CBM2080 is Pin to pin compatible with USB1.1 flash disk controller

CBM1180/CBM1183, This enables the manufacturers to have the exactly same BOM and PCB layout

for both USB1.1 and USB2.0 flash disk product.

The CBM2080/CBM1180/CBM1183 are available in 48-pin TQFP and 64-pin LQFP package, which are

thinnest and smallest on the market. The 48-pin CBM2080/CBM1180 CBM1183 supports up to 4 flash

chips and the 64-pin CBM2080L/CBM1180L CBM1183L supports up to 8 flash chips. Customers can

choose different packages to meet their design requirement.

The CBM2075 is a cost-effective general purpose USB2.0 device controller with embedded 32-bit

microprocessor. With 16 GPIO ports, it is available in 48-pin TQFP package.
