IntellaSys Announces Embedded 128-Bit, Hardware-Encrypted Controller Chip for Use With CompactFlash Memory or Hard Disk Drives

CUPERTINO, Calif.—(BUSINESS WIRE)—February 12, 2007— IntellaSys today announced its new OnSpec(TM) xSil261 controller chip with 128-bit, hardware-encrypted security for use with UDMA CompactFlash (CF) memory or IDE/ATAPI Hard Disk Drives using a USB 2.0 interface. The xSil261's hardware-embedded encryption/decryption function, fully compliant with the Advanced Encryption Standard (AES), combines with two-level software authentication of passwords to prevent unauthorized access of memory content.

"Our new xSil261 offers all the same attributes as our high-speed xSil251 - but with improved performance with PIO mode 6 and embedded security," said Bryan Chin, OnSpec product marketing manager. He noted that independent test results proved the xSil251 to be faster than any other options for enabling memory data transfers for a UDMA CF/Microdrive or IDE Hard Disk Drive using a USB 2.0 interface. "Like its industry-acclaimed predecessor, the xSil261 supports CF Cards along with the faster PIO 6 and UDMA 4 modes, while also providing a low-cost, easy-to-use USB 2.0 option for controlling external IDE Hard Drives singly or two of them as one."

Commenting on the xSil261's embedded security, Chin noted that any unauthorized attempt to decipher the xSil261's keys is virtually impossible as it would take 149 trillion years to determine all possibilities at an attempted recovery rate of one key per second. He attributed this extraordinary level of security to the 3.4x1038 possible options the xSil261 offers to code keys.

The xSil261 can be configured to manage either a USB-to-CF or USB-to-IDE/ATA interface, but not both simultaneously. Configured for the IDE/ATA interface, the xSil261 allows two hard drives to operate as one, providing a low-cost solution for data backup. "This feature can handle up to 2 terabytes capacity, making it far more attractive when you consider the alternative of using a single high-capacity Hard Drive at a premium price," added Chin.

IntellaSys supports its new chip with additional software that provides the end user with convenient features. OEMs opting to include this software with their xSil-based controllers can enable users to backup data with a simple one-touch pushbutton. For OEMs offering a portable USB to Hard Drive solution, OnSpec software also enables use of the drive independent of the PC system being used.


Packaged in a 48-pin 9mm x 9mm LQFP package, the new xSil261 chip is now in production and has begun sampling along with evaluation boards to qualified OEMS. Due to competitive strategies, OEM pricing information is being disclosed only to qualified manufacturers of CF/Microdrive and Hard Disk Drive products.
