Spansion has announced that designers of mainstream mobile phones and portable electronics gained new weapons against hackers, phone thieves and other high-tech criminals with the introduction of the S29PL family of Flash memory products.

The 128-, 64-, and 32Mb devices, claimed by the company as the industry's fastest for 3V wireless systems, use 110nm floating gate technology to provide the price-performance demanded for today's mainstream mobile product designs.

Advanced Sector Protection, available throughout the S29PL family, is claimed by Spansion as the industry's most robust Flash security feature set and the only one to feature password protection for everyday consumer products.

"Software-only security schemes are often not enough to protect our customers' critical program code and sensitive configuration information against sophisticated hardware-based attacks," said CTO Michael Van Buskirk. "Advanced Sector Protection, a hardware-based security system now standard on most Spansion products at the 110nm node, transforms Spansion Flash memory into a 'fortress on a circuit board' that helps prevent unauthorized users from altering or erasing protected program code and configuration information."

"The S29PL family delivers price-performance leadership by combining our strong tradition of cost reduction with the high performance and advanced security features once required by only the most advanced mobile designs," said Amir Mashkoori, group VP and GM of Spansion's Wireless Business Unit. "We have sampled thousands of units to our customers, who can see immediate system-level improvement over existing designs. We expect this trend to continue as future generations of this product family exploit our density-doubling MirrorBit technology."

The S29PL family features a 55ns random read time and a 20ns intra-page read time that provides up to 95MBps read throughput within the eight-word page and 78MBps sustained sequential read throughput across the device.

The devices also include a simultaneous read-write architecture that provides flexibility and streamlines coding for execute-in-place (XIP) applications.

The S29PL product family contains two distinct 128Mb products: the standard S29PL127J and the specialized S29PL129J. The S29PL129J features dual "chip-enable" inputs that enable designers to use a single-chip 128Mb solution on platforms otherwise limited to addressing 64Mb of memory. The product also provides the same performance as the standard S29PL127J while replacing two separate 64Mb devices to save board space and cost.

The S29PL product family is in volume production of 128Mb and 64Mb products, with 32Mb products to follow. The 128Mb, 64Mb, and 32Mb devices are priced at $12, $7, and $4 each, respectively, in quantities of 10,000.
