| IntellaSys Adds Two Memory Reader Controller Chips to OnSpec Line IntellaSys has expanded its OnSpec line of memory controllers with the addition of the xSil267 and xSil268, both of which enable secure and rapid USB data transfer from popular Flash and Hard Disk Drive media. While the xSil267 controls serial-only, multi-slot applications such as those where Secure Digital, Multimedia Card, and Memory Stick media interface with a PC Express Card adapter or USB Host, the xSil268 controls both serial and parallel interfaces for multi-slot applications enabling it to read from a wide range of media formats including UDMA CompactFlash, MMC 4.1, SD 2.0 and IDE/ATAPI HDD as well as their variants. Both new entries feature a 128-bit, hardware-embedded, encryption/decryption function that can be enabled via firmware. This is ideal for applications where a specific media is exclusively used and partitioned to store encrypted information. Fully compliant with the Advanced Encryption Standard, this security feature is augmented by two-level software authentication of passwords. According to Bryan Chin, OnSpec product marketing manager, any unauthorized attempts to decipher the 3.4x1038 keys embedded in each chip at rate of one key per second would take 149 trillion years to determine all possibilities. Designed with integrated USB 2.0 PHY, both xSil267 and xSil268 pack a 16-bit processor along with a serial EEPROM port, two general purpose timers and a watchdog timer. Moreover, each device supports both Reads and Writes for SD-HS compliant media with sustained transfer rates exceeding 20MB/s as well as MS PRO media with sustained transfer rates of up to 18MB/s and MMC cards that have 4-bit and 8-bit buses with sustained transfer rates of up to 20MB/s. Both devices also provide programmable R/W widths plus optimally controlled hardware transfer for speed and scalability. The xSil267 is packaged in a 48-pin 16mm x 16mm QFP while the xSil268 comes in a 100-pin 16mm x 16mm QFP. Both devices are in production and now sampling along with evaluation boards to qualified OEMS. write your comments about the article :: © 2007 Computing News :: home page |
