The EZ-USB NX2LP-Flex USB controller from Cypress Semiconductor Corp. is touted to be the industry's first firmware-programmable USB 2.0 high speed NAND flash controller. This device allows manufacturers to add value to commodity USB "thumbdrives," the most common application for NAND flash, by including features such as fingerprint sensors, video-over-USB and others. It also enables consumer electronics products such as DVB/PCTV cards, GPS receivers and wireless presenters to add NAND flash for their storage needs.

The EZ-USB NX2LP-Flex is the newest offering in Cypress's EZ-USB LP family of high speed USB controllers. The LP devices promise to slash dynamic and standby power consumption by nearly 50 percent versus alternative offerings.

"Market acceptance of our EZ-USB LP family of devices has exceeded our high expectations," said Matthew Branda, product marketing manager for USB products. "The NX2LP-Flex device adds to this family a uniquely programmable NAND flash controller that provides the hard-to-pair duo of simplifying design while allowing for increased functionality and integration. It addresses the needs of both thumbdrive and consumer electronics suppliers, and enables the convergence of these important and growing application segments."

Aside from complete programmability, another major benefit of the EZ-USB NX2LP-Flex is the elimination of EEPROM, normally required in a firmware-based design for code storage. According to the company, the elimination of EEPROM results in lower component cost, reduced power, board space savings and a simplified design process.

The EZ-USB NX2LP-Flex (CY7C68033/4) is in full production and is offered in a Pb-free 56-pin QFN package, in die-form for space-conscious applications, and in custom-programmed form for security applications. Depending on quantity and configuration, pricing ranges from $2.50 to $4. The CY3686 development kit is available for $495 each.
