Memory controller enables fast data transfers

IntellaSys Corp.'s new OnSpec xSil251 memory controller enables fast memory data transfers for UDMA CompactFlash (CF)/Microdrive or IDE Hard Disk Drive via USB 2.0 interface.

The xSil251 meets the growing OEM demand for a speedy controller on two fronts, first to support new media such as CF Cards in both PIO 6 and UDMA 4 modes, and secondly to provide a low-cost, easy-to-use USB 2.0 option for controlling external IDE Hard Drives singly or two of them as one.

"We believe our new xSil251 chip is the only controller available today with full UDMA 4 and PIO 6 support for the new CF Cards," said Bryan Chin, OnSpec product marketing manager. OnSpec is an operating entity of IntellaSys Corp. Chin added that "the only comparable speed option is to use a Firewire-to-CF solution, which is far more costly than using an xSil251-based controller offered by one of our OEM customers."

Chin noted that the xSil251 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 xSil251 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."

OnSpec 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.

The xSil251 chip, integrated with USB 2.0 PHY and Serial EEPROM port, has begun shipping to OEMs in a 48-pin 9-by-9mm LQFP package. OnSpec expects several OEMs to offer controllers to serve USB-to-CF and USB-to-IDE/ATA applications. Among the OEMs currently planning to bring xSil251-based controllers to market are Dura Micro Inc. and Ma Labs Inc.

The xSil 251 OnSpec Memory controller from Intellasys is now available for the sample price of $5 each. Substantial discounts for OEM quantities are available to qualified OEMs.
