IntellaSys OnSpec xSil269 Memory Controller Chip

IntellaSys’ OnSpec(TM) xSil269 memory controller chip is the industry’s first USB 2.0 NAND Flash controller with 128-bit, hardware-encrypted security. Fully compliant with the Advanced Encryption Standard (AES), the xSil269′s hardware-embedded encryption/decryption function combines with two-level software authentication of passwords to prevent unauthorized access of memory content.

Designed to connect with both USB1.1 and high-speed USB 2.0 host interfaces, the xSil269 supports NAND, NAND MLC and AG-AND Flash media. Up to four chip selects allow extended addressing. Integrating 4-byte Forward Error Correction (FEC) in a real-time, the new OnSpec chip also packs a 16-bit processor along with a serial port, two general purpose timers and a watchdog timer. Internal RAM supports enhancements as ROM stores BIOS and application code. In addition, on-board NAND Flash can be used to store firmware enhancements. The xSil269 also provides programmable R/W widths plus optimally controlled hardware transfer for speed and scalability.

Packaged in a 48-pin 9mm x 9mm LQFP package, the new xSil269 chip is in production and has been sampling with evaluations boards to qualified OEMS. Due to competitive strategies, OEM pricing information is being disclosed only to qualified manufacturers of thumb drives and/or other products using NAND Flash memory.
