Cypress Unveils Industry's First Firmware-Programmable USB2.0 NAND Controller

Single-Chip EZ-USB(TM) NX2LP-Flex Controller Enables Value Added Features In NAND Flash-Based Thumbdrives

SAN JOSE, Calif., Sep. 19, 2005 - Cypress Semiconductor Corp. (NYSE: CY), the market leader in USB, today introduced the EZ-USB NX2LP-Flex(TM) USB controller, the industry's first firmware-programmable USB2.0 high speed NAND flash controller.  The new controller 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, announced earlier this year. The LP devices slash dynamic and standby power consumption by nearly 50 percent versus. alternative offerings. Cypress recently announced that it has shipped over 5 million of the new devices in less than five months.

"Market acceptance of our EZ-USB LP family of devices has exceeded our high expectations," said Matthew Branda, product marketing manager for Cypress's 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."

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

Key features of the EZ-USB NX2LP-Flex include:

  • High performance 8-bit NAND controller with enhanced 8051 core and General Programmable Interface (GPIF)
  • Ultra-low power -- typically at 43 mA in active mode
  • 15 KBytes of on-chip code/data RAM
  • 12 fully-programmable GPIO pins
  • Supports write protect switch and LEDs for activity monitoring
  • Four programmable endpoints with double, triple, and quad buffering options
  • 4 KB integrated FIFOs with automatic conversion to and from 16-bit buses
  • The CY3686 EZ-USB NX2LP-Flex Silicon and Development Kit is available to facilitate the design process and speed time-to-market for customers
  • USBE2.0 - USB-IF high speed certified

Pricing and Availability
The EZ-USB NX2LP-Flex (CY7C68033/4) is in full production and is offered in a lead-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 $4.00. The CY3686 Development Kit is available for $495 each and can be purchased from Cypress distributors or our online store at" A high-resolution photo of the EZ-USB NX2LP-Flex can be downloaded at
