N25Q SPI flash memory

Numonyx B.V. has launched a 65nm multiple I/O serial flash memory product line designed for the rigorous code and data reliability needs of the embedded market. The new Numonyx Fort? N25Q serial flash family is designed to deliver the highest performance, flexibility and reliability for popular embedded applications found in PCs, STBs and communications devices.

The Numonyx Fort? N25Q product family is the latest offering from the expanding Fort? portfolio of SPI flash memory, delivering a broad spectrum of performance features and density ranges. Numonyx adds two new products at 128Mbit densities in 3V and 1.8V versions manufactured on 65nm technology. Using advanced technologies provides customers with cost-effective products and long-term architectural continuity.

"Numonyx Fort? N25Q represents another leap forward in our quest to deliver the most advanced memory solutions in the industry," says Glen Hawk, VP and general manager of the embedded business group at Numonyx. "As we expand the Fort? line, we're continuing to demonstrate that Numonyx is committed to the embedded segment and to being the serial flash leader in performance and solutions."

The latest product extends and improves the design flexibility and usability of serial flash memory with the introduction of the Non-Volatile Configuration Register. This new feature optimizes the device configuration by allowing multiple parameter options that are best-suited for the application and maintains the settings after the power on and off cycle. This non-volatile capability greatly enhances the flexibility of execute-in-place memory systems by eliminating the need to reset the device after each power cycle, and improves performance by reducing the number of clock cycles. Designing with the Fort? N25Q family also presents the opportunity to reduce the DRAM in the system by executing the code directly from the flash device, saving cost and board space for customers.

In addition, The N25Q serial flash memory supports multiple I/O SPI protocols (single, dual and quad,) on the same device, which delivers the highest level of design flexibility to customers. Numonyx has significantly improved the read and write speeds over the entire supply voltage range, improving clock speeds from 75MHz to 108MHz and up to four times, or 432MHz, in the Quad I/O mode. At both 3V and 1.8V, the Fort? N25Q is well-suited for a range of applications, including battery-operated devices such as handheld or consumer electronics.

Production quantities of the Fort? N25Q 128Mb in both 3V and1.8V are available now.
